The most +dramatic changes are in the alpha releases. Here is a list of possible +problems... + +No HTML when matching page elements +----------------------------------- +This behaviour has been switched to using plain text as if it +were seen by the user of the browser. This means that HTML tags +are suppressed, entities are converted and whitespace is +normalised. This should make it easier to match items in forms. +Also images are replaced with their "alt" text so that they +can be matched as well. + +No method SimpleRunner::_getTestCase() +-------------------------------------- +This was made public as getTestCase() in 1.0RC2. + +No method restartSession() +-------------------------- +This was renamed to restart() in the WebTestCase, SimpleBrowser +and the underlying SimpleUserAgent in 1.0RC2. Because it was +undocumented anyway, no attempt was made at backward +compatibility. + +My custom test case ignored by tally() +-------------------------------------- +The _assertTrue method has had it's signature changed due to a bug +in the PHP 5.0.1 release. You must now use getTest() from within +that method to get the test case. + +Broken code extending SimpleRunner +---------------------------------- +This was replaced with SimpleScorer so that I could use the runner +name in another class. This happened in RC1 development and there +is no easy backward compatibility fix. The solution is simply to +extend SimpleScorer instead. + +Missing method getBaseCookieValue() +----------------------------------- +This was renamed getCurrentCookieValue() in RC1. + +Missing files from the SimpleTest suite +--------------------------------------- +Versions of SimpleTest prior to Beta6 required a SIMPLE_TEST constant +to point at the SimpleTest folder location before any of the toolset +was loaded. This is no longer documented as it is now unnecessary +for later versions. If you are using an earlier version you may +need this constant. Consult the documentation that was bundled with +the release that you are using or upgrade to Beta6 or later. + +No method SimpleBrowser::getCurrentUrl() +-------------------------------------- +This is replaced with the more versatile showRequest() for +debugging. It only existed in this context for version Beta5. +Later versions will have SimpleBrowser::getHistory() for tracking +paths through pages. It is renamed as getUrl() since 1.0RC1. + +No method Stub::setStubBaseClass() +---------------------------------- +This method has finally been removed in 1.0RC1. Use +SimpleTestOptions::setStubBaseClass() instead. + +No class CommandLineReporter +---------------------------- +This was renamed to TextReporter in Beta3 and the deprecated version +was removed in 1.0RC1. + +No method requireReturn() +------------------------- +This was deprecated in Beta3 and is now removed. + +No method expectCookie() +------------------------ +This method was abruptly removed in Beta4 so as to simplify the internals +until another mechanism can replace it. As a workaround it is necessary +to assert that the cookie has changed by setting it before the page +fetch and then assert the desired value. + +No method clickSubmitByFormId() +------------------------------- +This method had an incorrect name as no button was involved. It was +renamed to submitByFormId() in Beta4 and the old version deprecated. +Now removed. + +No method paintStart() or paintEnd() +------------------------------------ +You should only get this error if you have subclassed the lower level +reporting and test runner machinery. These methods have been broken +down into events for test methods, events for test cases and events +for group tests. The new methods are... + +paintStart() --> paintMethodStart(), paintCaseStart(), paintGroupStart() +paintEnd() --> paintMethodEnd(), paintCaseEnd(), paintGroupEnd() + +This change was made in Beta3, ironically to make it easier to subclass +the inner machinery. Simply duplicating the code you had in the previous +methods should provide a temporary fix. + +No class TestDisplay +-------------------- +This has been folded into SimpleReporter in Beta3 and is now deprecated. +It was removed in RC1. + +No method WebTestCase::fetch() +------------------------------ +This was renamed get() in Alpha8. It is removed in Beta3. + +No method submit() +------------------ +This has been renamed clickSubmit() in Beta1. The old method was +removed in Beta2. + +No method clearHistory() +------------------------ +This method is deprecated in Beta2 and removed in RC1. + +No method getCallCount() +------------------------ +This method has been deprecated since Beta1 and has now been +removed. There are now more ways to set expectations on counts +and so this method should be unecessery. Removed in RC1. + +Cannot find file * +------------------ +The following public name changes have occoured... + +simple_html_test.php --> reporter.php +simple_mock.php --> mock_objects.php +simple_unit.php --> unit_tester.php +simple_web.php --> web_tester.php + +The old names were deprecated in Alpha8 and removed in Beta1. + +No method attachObserver() +-------------------------- +Prior to the Alpha8 release the old internal observer pattern was +gutted and replaced with a visitor. This is to trade flexibility of +test case expansion against the ease of writing user interfaces. + +Code such as... + +$test = &new MyTestCase(); +$test->attachObserver(new TestHtmlDisplay()); +$test->run(); + +...should be rewritten as... + +$test = &new MyTestCase(); +$test->run(new HtmlReporter()); + +If you previously attached multiple observers then the workaround +is to run the tests twice, once with each, until they can be combined. +For one observer the old method is simulated in Alpha 8, but is +removed in Beta1. + +No class TestHtmlDisplay +------------------------ +This class has been renamed to HtmlReporter in Alpha8. It is supported, +but deprecated in Beta1 and removed in Beta2. If you have subclassed +the display for your own design, then you will have to extend this +class (HtmlReporter) instead. + +If you have accessed the event queue by overriding the notify() method +then I am afraid you are in big trouble :(. The reporter is now +carried around the test suite by the runner classes and the methods +called directly. In the unlikely event that this is a problem and +you don't want to upgrade the test tool then simplest is to write your +own runner class and invoke the tests with... + +$test->accept(new MyRunner(new MyReporter())); + +...rather than the run method. This should be easier to extend +anyway and gives much more control. Even this method is overhauled +in Beta3 where the runner class can be set within the test case. Really +the best thing to do is to upgrade to this version as whatever you were +trying to achieve before should now be very much easier. + +Missing set options method +-------------------------- +All test suite options are now in one class called SimpleTestOptions. +This means that options are set differently... + +GroupTest::ignore() --> SimpleTestOptions::ignore() +Mock::setMockBaseClass() --> SimpleTestOptions::setMockBaseClass() + +These changed in Alpha8 and the old versions are now removed in RC1. + +No method setExpected*() +------------------------ +The mock expectations changed their names in Alpha4 and the old names +ceased to be supported in Alpha8. The changes are... + +setExpectedArguments() --> expectArguments() +setExpectedArgumentsSequence() --> expectArgumentsAt() +setExpectedCallCount() --> expectCallCount() +setMaximumCallCount() --> expectMaximumCallCount() + +The parameters remained the same. diff --git a/tests/test_tools/simpletest/HtmlReporterWithCoverage.php b/tests/test_tools/simpletest/HtmlReporterWithCoverage.php new file mode 100644 index 00000000..abd10076 --- /dev/null +++ b/tests/test_tools/simpletest/HtmlReporterWithCoverage.php @@ -0,0 +1,268 @@ +<?php + +if (!defined('T_ML_COMMENT')) + define('T_ML_COMMENT', T_COMMENT); +else + define('T_DOC_COMMENT', T_ML_COMMENT); + +class HtmlReporterWithCoverage extends HtmlReporter +{ + protected $coverage = array(); + + protected $painter; + + protected $base_dir; + + function __construct($painter = 'index.php', $base_dir) + { + $this->painter = $painter; + $this->base_dir = $base_dir; + } + + function paintHeader($test_name, $charset="UTF-8") + { + $this->sendNoCacheHeaders(); + header('Content-Type: text/html; Charset='.$charset); + print "<html>\n<head>\n<title>$test_name</title>\n"; + print "<meta http-equiv=\"Content-Type\" content=\"text/html; charset={$charset}\"/>"; + print "<style type=\"text/css\">\n"; + print $this->_getCss() .

It's a framework for unit testing, web site testing and +mock objects for PHP 4.2.0+. + +If you have used JUnit you will find this PHP unit testing version very +similar. Also included is a mock objects and server stubs generator. +The stubs can have return values set for different arguments, can have +sequences set also by arguments and can return items by reference. +The mocks inherit all of this functionality and can also have +expectations set, again in sequences and for different arguments. + +A web tester similar in concept to JWebUnit is also included. There is no +JavaScript or tables support, but forms, authentication, cookies and +frames are handled. + +You are not tied to just using SimpleTest, though. The mocks and stubs +will work with other test frameworks and SimpleTest can use other +framework's (PHPUnit, PEAR::PhpUnit) test cases as it's own. The +web browser part of the web tester can also be used independently either +in other testers or as part of a scripting solution. + +You can see a release schedule at http://www.lastcraft.com/overview.php +which is also copied to the documentation folder with this release. +A full PHPDocumenter API documentation exists at +http://simpletest.sourceforge.net/. + +The user interface is minimal +in the extreme, but a lot of information flows from the test suite. +After version 1.0 we will release a better web UI, but we are leaving XUL +and GTk versions to volunteers as everybody has their own opinion +on a good GUI, and we don't want to discourage development by shipping +one with the toolkit. + +You are looking at a first full release. The unit tests for SimpleTest +itself can be run here... + +simpletest/test/unit_tests.php + +And tests involving live network connections as well are here... + +simpletest/test/all_tests.php + +The full tests will typically overrun the 8Mb limit usually allowed +to a PHP process. A workaround is to run the tests on the command +with a custom php.ini file if you do not have access to your server +version. + +You will have to edit the all_tests.php file if you are accesssing +the internet through a proxy server. See the comments in all_tests.php +for instructions. + +The full tests read some test data from the LastCraft site. If the site +is down or has been modified for a later version then you will get +spurious errors. A unit_tests.php failure on the other hand would be +very serious.

It also points out +deprecated interfaces so you should read this even if all of +your current tests appear to run. + +There is a documentation folder which contains the core reference information +in English and French, although this information is fairly basic. +You can find a tutorial on http://www.lastcraft.com/first_test_tutorial.php +to get you started and this material will eventually become included +with the project documentation.

You can visit the +release notes to see the completed TODO list after each cycle and also the +status of any bugs, but if the bug is recent then it will be fixed in CVS only. +The CVS check-ins always have all the tests passing and so CVS snapshots should +be pretty usable, although the code may not look so good internally. + +Oh, yes. It is called "Simple" because it should be simple to +use. We intend to add a complete set of tools for a test first +and "test as you code" type of development.

a very rapid solution. + </p> + <p> + All of the navigation methods used in the + <a href="web_tester_documentation.html">WebTestCase</a> + are present in the <span

helpful error + message when something goes wrong. + You want to test that the correct error was sent, but the actual + text may be rather long. + If you test for the text exactly, then every time the exact wording + of the message changes, you will have to go back and edit the test suite. + </p> + <p> + For example, suppose we have a news service that has failed + to connect to its remote source.

approaches to creating mocks including the one + that SimpleTest employs. + Coding them by hand using a base class, generating them to + a file and dynamically generating them on the fly. + </p> + <p> + Mock objects generated with <a href="simple_test.html">SimpleTest</a> + are dynamic. + They are created at run time in memory, using + <span class="new_code">eval()</span>, rather than written + out to a file. + This makes the mocks easy to create, a one liner, + especially compared with hand + crafting them in a parallel class hierarchy. + The problem is that the behaviour is usually set up in the tests + themselves. + If the original objects change the mock versions + that the tests rely on can get out of sync. + This can happen with the parallel hierarchy approach as well, + but is far more quickly detected. + </p> + <p> + The solution, of course, is to add some real integration + tests. + You don't need very many and the convenience gained + from the mocks more than outweighs the small amount of + extra testing. + You cannot trust code that was only tested with mocks. + </p> + <p> + If you are still determined to build static libraries of mocks + because you want to simulate very specific behaviour, you can + achieve the same effect using the SimpleTest class generator. + In your library file, say <em>mocks/connection.php</em> for a + database connection, create a mock and inherit to override + special methods or add presets... +<pre> +<?php + require_once('simpletest/mock_objects.php'); + require_once('../classes/connection.php'); +<strong> + Mock::generate('Connection', 'BasicMockConnection'); + class MockConnection extends BasicMockConnection { + function MockConnection(&$test, $wildcard = '*') { + $this->BasicMockConnection($test, $wildcard); + $this->setReturn('query', false); + } + }</strong> +?> +</pre> + The generate call tells the class generator to create + a class called <span class="new_code">BasicMockConnection</span> + rather than the usual <span class="new_code">MockConnection</span>. + We then inherit from this to get our version of + <span class="new_code">MockConnection</span>. + By intercepting in this way we can add behaviour, here setting + the default value of <span class="new_code">query()</span> to be false. + By using the default name we make sure that the mock class + generator will not recreate a different one when invoked elsewhere in the + tests. + It never creates a class if it already exists. + As long as the above file is included first then all tests + that generated <span class="new_code">MockConnection</span> should + now be using our one instead. + If we don't get the order right and the mock library + creates one first then the class creation will simply fail. + </p> + <p> + Use this trick if you find you have a lot of common mock behaviour + or you are getting frequent integration problems at later + stages of testing. + </p> + + <p> +<a class="target" name="other_testers"> +<h2>I think SimpleTest stinks!</h2> +</a> +</p> + <p> + But at the time of writing it is the only one with mock objects, + so are you stuck with it? + </p> + <p> + No, not at all. + <a href="simple_test.html">SimpleTest</a> is a toolkit and one of those + tools is the mock objects which can be employed independently. + Suppose you have your own favourite unit tester and all your current + test cases are written using it. + Pretend that you have called your unit tester PHPUnit (everyone else has) + and the core test class looks like this... +<pre> +class PHPUnit { + function PHPUnit() { + } + + function assertion($message, $assertion) { + } + ... +} +</pre> + All the <span class="new_code">assertion()</span> method does + is print some fancy output and the

exists', file_exists('my_file')); +</pre> + How do you use mocks with this? + </p> + <p> + There is a protected method on the base mock class + <span class="new_code">SimpleMock</span> called + <span class="new_code">_assertTrue()</span> and + by overriding this method we can use our own assertion format. + We start with a subclass, in say <em>my_mock.php</em>... +<pre> +<strong><?php +

SimpleTestOptions::setMockBaseClass('MyMock');</strong> +?> +</pre> + From now on you just include <em>my_mock.php</em> instead of the + default <em>mock_objects.php</em> version and you can introduce

SimpleTest</h1> +<div class="content"> + <p> +<a class="target" name="summary"> +<h2>What is SimpleTest?</h2> +</a> +</p> + <p> + The heart of SimpleTest is a testing framework built around + test case classes. + These are written as extensions of base test case classes, + each extended with methods that actually contain test code. + Top level test scripts then invoke the <span class="new_code">run()</span> + methods on every one of these test cases in order. + Each test method is written to invoke various assertions that + the developer expects to be true such as + <span class="new_code">assertEqual()</span>. + If the expectation is correct, then a successful result is dispatched to the + observing test reporter, but any failure triggers an alert + and a description of the mismatch. + </p> + <p> + A <a href="unit_test_documentation.html">test case</a> looks like this... +<pre> +<?php +class <strong>MyTestCase</strong> extends UnitTestCase { + <strong> + function testLog() { + $log = &new Log('my.log'); + $log->message('Hello'); + $this->assertTrue(file_exists('my.log')); + }</strong> +} +?> +</pre> + </p> + <p> + These tools are designed for the developer. + Tests are written in the PHP language itself more or less + as the application itself is built. + The advantage of using PHP itself as the testing language is that + there are no new languages to learn, testing can start straight away, + and the developer can test any part of the code. + Basically, all parts that can be accessed by the application code can also be + accessed by the test code if they are in the same language. + </p> + <p> + The simplest type of test case is the + <a href="unit_tester_documentation.html">UnitTestCase</a>. + This class of test case includes standard tests for equality, + references and pattern matching. + All these test the typical expectations of what you would + expect the result of a function or method to be. + This is by far the most common type of test in the daily + routine of development, making up about 95% of test cases. + </p> + <p> + The top level task of a web application though is not to + produce correct output from its methods and objects, but + to generate web pages. + The <a href="web_tester_documentation.html">WebTestCase</a> class tests web + pages. + It simulates a web browser requesting a page, complete with + cookies, proxies, secure connections, authentication, forms, frames and most + navigation elements. + With this type of test case, the developer can assert that + information is present in the page and that forms and + sessions are handled correctly. + </p> + <p> + A <a href="web_tester_documentation.html">WebTestCase</a> looks like this... +<pre> +<?php +class <strong>MySiteTest</strong> extends WebTestCase { + <strong> + function testHomePage() { + $this->get('http://www.my-site.com/index.php'); + $this->assertTitle('My Home Page'); + $this->clickLink('Contact'); +

+ + class Telnet { + ... + <strong>function &connect(&$socket, $username, $password) { + $socket->read( ... ); + ... + }</strong> + } +?> +</pre> + This means that the test code is typical for a test involving + mock objects. +<pre> +class TelnetTest extends UnitTestCase { + ... + function testConnection() {<strong> + $socket = &new MockSocket($this);

+</pre> + ...it will return "admin". + It finds this by attempting to match the calling arguments + to its list of returns one after another until + a complete match is found. + </p> + <p> + You can set a default argument argument like so... +<pre> +<strong> +$config->setReturnValue('getValue', false, array('*'));</strong> +</pre> + This is not the same as setting the return value without + any argument requirements like this... +<pre> +<strong> +$config->setReturnValue('getValue', false);</strong> +</pre> + In the first case it will accept any single argument, + but exactly one is required. + In the second case any number of arguments will do and + it acts as a catchall after all other matches. + Note that if we add further single parameter options after + the wildcard in the first case, they will be ignored as the wildcard + will match first. + With complex parameter lists the ordering could be important + or else desired matches could be masked by earlier wildcard + ones. + Declare the most specific matches first if you are not sure. + </p> + <p> + There are times when you want a specific object to be + dished out by the stub rather than just a copy. + The PHP copy semantics force us to use a different method + for this. + You might be simulating a container for example... +<pre> +class Thing { +} + +class Vector { + function Vector() { + } + + function get($index) { + } +} +</pre> + In this case you can set a reference into the stub's + return list... +<pre> +Stub::generate('Vector');

frame then it cannot + be clicked. + </p> + <p> + Testing navigation on fixed pages only tells you when you + have broken an entire script. + For highly dynamic pages, such as for bulletin boards,

SimpleTest essaie d'émuler le comportement typique d'un navigateur autant que possible, plutôt que d'essayer d'attraper des attributs manquants sur les balises. La raison est simple : la cible d'un framework de test est la logique d'une application PHP, pas les erreurs -- de syntaxe ou autres -- du code HTML.

Supposons que la classe <span class="new_code">Log</span> prenne le nom du fichier à écrire dans le constructeur et que nous ayons un répertoire temporaire dans lequel placer ce fichier... +<pre> +<?php +require_once('simpletest/unit_tester.php'); +require_once('simpletest/reporter.php'); +require_once('../classes/log.php'); + +class TestOfLogging extends UnitTestCase { + <strong> + function testCreatingNewFile() { + @unlink('/temp/test.log'); + $log = new Log('/temp/test.log'); + $this->assertFalse(file_exists('/temp/test.log')); + $log->message('Should write this to a file'); + $this->assertTrue(file_exists('/temp/test.log')); + }</strong> +} +?> +</pre> + Au lancement du scénario de test, toutes les méthodes qui commencent avec la chaîne <span class="new_code">test</span> sont identifiées puis exécutées. D'ordinaire nous avons bien plusieurs méthodes de tests. Les assertions dans les méthodes de test envoient des messages vers le framework de test qui affiche immédiatement le résultat. Cette réponse immédiate est importante, non seulement lors d'un crash causé par le code, mais aussi de manière à rapprocher l'affichage de l'erreur au plus près du scénario de test concerné. + </p> + <p> + Pour voir ces résultats lançons effectivement les tests. S'il s'agit de l'unique scénario de test à lancer, on peut y arriver avec... +<pre> +<?php +require_once('simpletest/unit_tester.php'); +require_once('simpletest/reporter.php'); +require_once('../classes/log.php'); + +class TestOfLogging extends UnitTestCase { + + function testCreatingNewFile() { + @unlink('/temp/test.log'); + $log = new Log('/temp/test.log'); + $this->assertFalse(file_exists('/temp/test.log')); + $log->message('Should write this to a file'); + $this->assertTrue(file_exists('/temp/test.log')); + } +} +<strong> +$test = &new TestOfLogging(); +$test->run(new HtmlReporter());</strong> +?> +</pre> + </p> + <p> + En cas échec, l'affichage ressemble à... + <div class="demo"> + <h1>testoflogging</h1> + <span class="fail">Fail</span>: testcreatingnewfile->True assertion failed.<br> + <div style="padding: 8px; margin-top: 1em; background-color: red; color: white;">1/1 test cases complete. + <strong>1</strong> passes and <strong>1</strong> fails.</div> + </div> + ...et si ça passe, on obtient... + <div class="demo"> + <h1>testoflogging</h1> + <div style="padding: 8px; margin-top: 1em; background-color: green; color: white;">1/1 test cases complete. + <strong>2</strong> passes and <strong>0</strong> fails.</div> + </div> + Et si vous obtenez ça... + <div class="demo"> + <b>Fatal error</b>: Failed opening required '../classes/log.php' (include_path='') in <b>/home/marcus/projects/lastcraft/tutorial_tests/Log/tests/log_test.php</b> on line <b>7</b> + </div> + c'est qu'il vous manque le fichier <em>classes/Log.php</em> qui pourrait ressembler à : +<pre> +<?php +class Log { + + function Log($file_path) { + } +} +?>; +</pre> + </p> + + <p> +<a class="target" name="group"> +<h2>Construire des groupes de tests</h2> +</a> +</p> + <p> + Il est peu probable que dans une véritable application on ait uniquement besoin de passer un seul scénario de test. Cela veut dire que nous avons besoin de grouper les scénarios dans un script de test qui peut, si nécessaire, lancer tous les tests de l'application. + </p> + <p> + Notre première étape est de supprimer les includes et de défaire notre hack précédent... +<pre> +<?php<strong> +require_once('../classes/log.php');</strong> + +class TestOfLogging extends UnitTestCase { + + function testCreatingNewFile() { + @unlink('/temp/test.log'); + $log = new Log('/temp/test.log'); + $this->assertFalse(file_exists('/temp/test.log')); + $log->message('Should write this to a file'); + $this->assertTrue(file_exists('/temp/test.log'));<strong> + } +} +?></strong> +</pre> + Ensuite nous créons un nouveau fichier appelé <em>tests/all_tests.php</em>. On y insert le code suivant... +<pre> +<strong><?php +require_once('simpletest/unit_tester.php'); +require_once('simpletest/reporter.php'); + +$test = &new GroupTest('All tests'); +$test->addTestFile('log_test.php'); +$test->run(new HtmlReporter()); +?></strong> +</pre> + Cette méthode <span class="new_code">GroupTest::addTestFile()</span> va inclure le fichier de scénarios de test et lire parmi toutes les nouvelles classes créées celles qui sont issues de <span class="new_code">TestCase</span>. Dans un premier temps, seuls les noms sont stockés, de la sorte le lanceur de test peut instancier la classe au fur et à mesure qu'il exécute votre suite de tests. + </p> + <p> + Pour que ça puisse marcher proprement le fichier de suite de tests ne devrait pas inclure aveuglement d'autres extensions de scénarios de test qui n'exécuteraient pas effectivement de test. Le résultat pourrait être que des tests supplémentaires soient alors être comptabilisés pendant l'exécution des tests. Ce n'est pas un problème grave mais pour éviter ce désagrément, il suffit d'ajouter la commande <span class="new_code">SimpleTestOptions::ignore()</span> quelque part dans le fichier de scénario de test. Par ailleurs le scénario de test ne devrait pas avoir été inclus ailleurs ou alors aucun scénario ne sera ajouté aux groupes de test. Il s'agirait là d'une erreur autrement sérieuse : si tous les classes de scénario de test sont chargées par PHP, alors la méthode <span class="new_code">GroupTest::addTestFile()</span> ne pourra pas les détecter. + </p> + <p> + Pour afficher les résultats, il est seulement nécessaire d'invoquer <em>tests/all_tests.php</em> à partir du serveur web. + </p> + + <p> +<a class="target" name="mock"> +<h2>Utiliser les objets fantaisie</h2> +</a> +</p> + <p> + Avançons un peu plus dans le futur. + </p> + <p> + Supposons que notre class logging soit testée et terminée. Supposons aussi que nous testons une autre classe qui ait besoin d'écrire des messages de log, disons <span class="new_code">SessionPool</span>. Nous voulons tester une méthode qui ressemblera probablement à quelque chose comme... +<pre> +<strong> +class SessionPool { + ... + function logIn($username) { + ... + $this->_log->message('User $username logged in.'); + ... + } + ... +} +</strong> +</pre> + Avec le concept de "réutilisation de code" comme fil conducteur, nous utilisons notre class <span class="new_code">Log</span>.

Nous passons du temps à tripoter les fichiers de log qui ne font pas partie de notre test. Pire, nous avons créé des liens de proximité entre la classe <span class="new_code">Log</span> et ce test. Que se passerait-il si nous n'utilisions plus de fichiers, mais la bibliothèque <em>syslog</em> à la place ? Avez-vous remarqué le retour chariot supplémentaire à la fin du message ? A-t-il été ajouté par le loggueur ? Et si il ajoutait aussi un timestamp ou d'autres données ? + </p> + <p> + L'unique partie à tester réellement est l'envoi d'un message précis au loggueur. Nous réduisons le couplage en créant une fausse classe de logging : elle ne fait qu'enregistrer le message pour le test, mais ne produit aucun résultat. Sauf qu'elle doit ressembler exactement à l'original. + </p> + <p> + Si l'objet fantaisie n'écrit pas dans un fichier alors nous nous épargnons la suppression du fichier avant et après le test. Nous pourrions même nous épargner quelques lignes de code supplémentaires si l'objet fantaisie pouvait exécuter l'assertion. + <p> + </p> + Trop beau pour être vrai ? Par chance on peut créer un tel objet très facilement... +<pre> +<?php +require_once('../classes/log.php'); +require_once('../classes/session_pool.php');<strong> +Mock::generate('Log');</strong> + +class TestOfSessionLogging extends UnitTestCase { + + function testLogInIsLogged() {<strong> + $log = &new MockLog($this); + $log->expectOnce('message', array('User fred logged in.'));</strong> + $session_pool = &new SessionPool($log); + $session_pool->logIn('fred');<strong> + $log->tally();</strong> + } +} +?> +</pre> + L'appel <span class="new_code">tally()</span> est nécessaire pour annoncer à l'objet fantaisie qu'il n'y aura plus d'appels ultérieurs. Sans ça l'objet fantaisie pourrait attendre pendant une éternité l'appel de la méthode sans jamais prévenir le scénario de test. Les autres tests sont déclenchés automatiquement quand l'appel à <span class="new_code">message()</span> est invoqué sur l'objet <span class="new_code">MockLog</span>. L'appel <span class="new_code">mock</span> va déclencher une comparaison des paramètres et ensuite envoyer le message "pass" ou "fail" au test pour l'affichage. Des jokers peuvent être inclus ici aussi afin d'empêcher que les tests ne deviennent trop spécifiques. + </p> + <p> + Les objets fantaisie dans la suite SimpleTest peuvent avoir un ensemble de valeurs de sortie arbitraires, des séquences de sorties, des valeurs de sortie sélectionnées à partir des arguments d'entrée, des séquences de paramètres attendus et des limites sur le nombre de fois qu'une méthode peut être invoquée. + </p> + <p> + Pour que ce test fonctionne la librairie avec les objets fantaisie doit être incluse dans la suite de tests, par exemple dans <em>all_tests.php</em>. + </p> + + <p> +<a class="target" name="web"> +<h2>Tester une page web</h2> +</a> +</p> + <p> + Une des exigences des sites web, c'est qu'ils produisent des pages web.

Le cas classique est celui de la connexion à une base de données. Mettre sur pied une base de données de test au lancement de chaque test ralentirait considérablement les tests et en plus exigerait l'installation d'un moteur de base de données ainsi que des données sur la machine de test. Si nous pouvons simuler la connexion et renvoyer des données à notre guise alors non seulement nous gagnons en pragmatisme sur les tests mais en sus nous pouvons nourrir notre base avec des données falsifiées et voir comment il répond. Nous pouvons simuler une base de données en suspens ou d'autres cas extrêmes sans avoir à créer une véritable panne de base de données. En d'autres termes nous pouvons gagner en contrôle sur l'environnement de test. + </p> + <p> + Si les objets fantaisie ne se comportaient que comme des acteurs alors on les connaîtrait sous le nom de <a href="server_stubs_documentation.html">bouchons serveur</a>. + </p> + <p> + Cependant non seulement les objets fantaisie jouent un rôle (en fournissant à la demande les valeurs requises) mais en plus ils sont aussi sensibles aux messages qui leur sont envoyés (par le biais d'attentes). En posant les paramètres attendus d'une méthode ils agissent comme des gardiens : un appel sur eux doit être réalisé correctement. Si les attentes ne sont pas atteintes ils nous épargnent l'effort de l'écriture d'une assertion de test avec échec en réalisant cette tâche à notre place. Dans le cas d'une connexion à une base de données imaginaire ils peuvent tester si la requête, disons SQL, a bien été formé par l'objet qui utilise cette connexion. Mettez-les sur pied avec des attentes assez précises et vous verrez que vous n'aurez presque plus d'assertion à écrire manuellement. + </p> + + <p> +<a class="target" name="creation"> +<h2>Créer des objets fantaisie</h2> +</a> +</p> + <p> + Comme pour la création des bouchons serveur, tout ce dont nous avons besoin c'est d'un classe existante. La fameuse connexion à une base de données qui ressemblerait à... +<pre> +<strong>class DatabaseConnection { + function DatabaseConnection() { + } + + function query() { + } + + function selectQuery() { + } +}</strong> +</pre> + Cette classe n'a pas encore besoin d'être implémentée. Pour en créer sa version fantaisie nous devons juste inclure la librairie d'objet fantaisie puis lancer le générateur... +<pre> +<strong>require_once('simpletest/unit_tester.php'); +require_once('simpletest/mock_objects.php'); +require_once('database_connection.php'); + +Mock::generate('DatabaseConnection');</strong> +</pre> + Ceci génère une classe clone appelée <span class="new_code">MockDatabaseConnection</span>. Nous pouvons désormais créer des instances de cette nouvelle classe à l'intérieur même de notre scénario de test... +<pre> +require_once('simpletest/unit_tester.php'); +require_once('simpletest/mock_objects.php'); +require_once('database_connection.php'); + +Mock::generate('DatabaseConnection'); +<strong> +class MyTestCase extends UnitTestCase { + + function testSomething() { + $connection = &new MockDatabaseConnection($this); + } +}</strong> +</pre> + Contrairement aux bouchons, le constructeur d'une classe fantaisie a besoin d'une référence au scénario de test pour pouvoir transmettre les succès et les échecs pendant qu'il vérifie les attentes. Concrètement ça veut dire que les objets fantaisie ne peuvent être utilisés qu'au sein d'un scénario de test. Malgré tout, cette puissance supplémentaire implique que les bouchons ne sont que rarement utilisés si des objets fantaisie sont disponibles. + </p> + <p> + <a class="target" name="bouchon"> +<h2>Objets fantaisie en action</h2> +</a> + </p> + <p> + La version fantaisie d'une classe contient toutes les méthodes de l'originale. De la sorte une opération comme <span class="new_code">$connection->query()</span> est encore possible. Tout comme avec les bouchons, nous pouvons remplacer la valeur nulle renvoyée par défaut... +<pre> +<strong>$connection->setReturnValue('query', 37);</strong> +</pre> + Désormais à chaque appel de <span class="new_code">$connection->query()</span> nous recevons comme résultat 37. Tout comme avec les bouchons nous pouvons utiliser des jokers et surcharger le paramètre joker. Nous pouvons aussi ajouter des méthodes supplémentaires à l'objet fantaisie lors de sa génération et lui choisir un nom de classe qui lui soit propre... +<pre> +<strong>Mock::generate('DatabaseConnection', 'MyMockDatabaseConnection', array('setOptions'));</strong> +</pre> + Ici l'objet fantaisie se comportera comme si <span class="new_code">setOptions()</span> existait dans la classe originale. C'est pratique si une classe a utilisé le mécanisme <span class="new_code">overload()</span> de PHP pour ajouter des méthodes dynamiques. Vous pouvez créer des fantaisies spéciales pour simuler cette situation. + </p> + <p> + Tous les modèles disponibles avec les bouchons serveur le sont également avec les objets fantaisie... +<pre> +class Iterator { + function Iterator() { + } + + function next() { + } +} +</pre> + Une nouvelle fois, supposons que cet itérateur ne retourne que du texte jusqu'au moment où il atteint son terme, quand il renvoie <span class="new_code">false</span>. Nous pouvons le simuler avec... +<pre> +Mock::generate('Iterator'); + +class IteratorTest extends UnitTestCase() { + + function testASequence() {<strong> + $iterator = &new MockIterator($this); + $iterator->setReturnValue('next', false); + $iterator->setReturnValueAt(0, 'next', 'First string'); + $iterator->setReturnValueAt(1, 'next', 'Second string');</strong> + ... + } +} +</pre> + Au moment du premier appel à <span class="new_code">next()</span> sur l'itérateur fantaisie il renverra tout d'abord "First string", puis ce sera au tour de "Second string" au deuxième appel et ensuite pour tout appel suivant <span class="new_code">false</span> sera renvoyé. Ces valeurs renvoyées successivement sont prioritaires sur la valeur constante retournée. Cette dernière est un genre de valeur par défaut si vous voulez. + </p> + <p> + Reprenons aussi le conteneur d'information bouchonné avec des pairs clef / valeur... +<pre> +class Configuration { + function Configuration() { + } + + function getValue($key) { + } +} +</pre> + Il s'agit là d'une situation classique d'utilisation d'objets fantaisie étant donné que la configuration peut varier grandement de machine à machine : ça contraint fortement la fiabilité de nos tests si nous l'utilisons directement. Le problème est que toutes les données nous parviennent à travers la méthode <span class="new_code">getValue()</span> et que nous voulons des résultats différents pour des clefs différentes. Heureusement les objets fantaisie ont un système de filtrage... +<pre> +<strong>$config = &new MockConfiguration($this); +$config->setReturnValue('getValue', 'primary', array('db_host')); +$config->setReturnValue('getValue', 'admin', array('db_user')); +$config->setReturnValue('getValue', 'secret', array('db_password'));</strong> +</pre> + Le paramètre en plus est une liste d'arguments à faire correspondre. Dans ce cas nous essayons de faire correspondre un unique argument : en l'occurrence la clef recherchée. Maintenant que la méthode <span class="new_code">getValue()</span> est invoquée sur l'objet fantaisie... +<pre> +$config->getValue('db_user') +</pre> + ...elle renverra "admin". Elle le trouve en essayant de faire correspondre les arguments entrants dans sa liste d'arguments sortants les uns après les autres jusqu'au moment où une correspondance exacte est atteinte. + </p> + <p> + Il y a des fois où vous souhaitez qu'un objet spécifique soit servi par la fantaisie plutôt qu'une copie. De nouveau c'est identique au mécanisme des bouchons serveur... +<pre> +class Thing { +} + +class Vector { + function Vector() { + } + + function get($index) { + } +} +</pre> + Dans ce cas vous pouvez placer une référence dans la liste renvoyée par l'objet fantaisie... +<pre> +$thing = new Thing();<strong> +$vector = &new MockVector($this); +$vector->setReturnReference('get', $thing, array(12));</strong> +</pre> + Avec cet arrangement vous savez qu'à chaque appel de <span class="new_code">$vector->get(12)</span> le même <span class="new_code">$thing</span> sera renvoyé. + </p> + + <p> +<a class="target" name="attentes"> +<h2>Objets fantaisie en critique</h2> +</a> +</p> + <p> + Même si les bouchons serveur vous isolent du désordre du monde réel, il ne s'agit là que de la moitié du bénéfice potentiel. Vous pouvez avoir une classe de test recevant les messages ad hoc, mais est-ce que votre nouvelle classe renvoie bien les bons ? Le tester peut devenir cafouillis sans une librairie d'objets fantaisie. + </p> + <p> + Pour l'exemple, prenons une classe <span class="new_code">SessionPool</span> à laquelle nous allons ajouter une fonction de log. Plutôt que de complexifier la classe originale, nous souhaitons ajouter ce comportement avec un décorateur (GOF). Pour l'instant le code de <span class="new_code">SessionPool</span> ressemble à... +<pre> +<strong>class SessionPool { + function SessionPool() { + ... + } + + function &findSession($cookie) { + ... + } + ... +} + +class Session { + ... +}</strong> + +</pre> + Alors que pour notre code de log, nous avons... +<pre> +<strong> +class Log { + function Log() { + ... + } + + function message() { + ... + } +} + +class LoggingSessionPool { + function LoggingSessionPool(&$session_pool, &$log) { + ... + } + + function &findSession(\$cookie) { + ... + } + ... +}</strong> +</pre> + Dans tout ceci, la seule classe à tester est <span class="new_code">LoggingSessionPool</span>. En particulier, nous voulons vérifier que la méthode <span class="new_code">findSession()</span> est appelée avec le bon identifiant de session au sein du cookie et qu'elle renvoie bien le message "Starting session $cookie" au loggueur. + </p> + <p> + Bien que nous ne testions que quelques lignes de code de production, voici la liste des choses à faire dans un scénario de test conventionnel : + <ol> + <li>Créer un objet de log.</li> + <li>Indiquer le répertoire d'écriture du fichier de log.</li> + <li>Modifier les droits sur le répertoire pour pouvoir y écrire le fichier.</li> + <li>Créer un objet <span class="new_code">SessionPool</span>.</li> + <li>Lancer une session, ce qui demande probablement pas mal de choses.</li> + <li>Invoquer <span class="new_code">findSession()</span>.</li> + <li>Lire le nouvel identifiant de sessions (en espérant qu'il existe un accesseur !).</li> + <li>Lever une assertion de test pour vérifier que cet identifiant correspond bien au cookie.</li> + <li>Lire la dernière ligne du fichier de log.</li> + <li>Supprimer avec une (ou plusieurs) expression rationnelle les timestamps de log en trop, etc.</li> + <li>Vérifier que le message de session est bien dans le texte.</li> + </ol> + Pas étonnant que les développeurs détestent écrire des tests quand ils sont aussi ingrats. Pour rendre les choses encore pire, à chaque fois que le format de log change ou bien que la méthode de création des sessions change, nous devons réécrire une partie des tests alors même qu'ils ne testent pas ces parties du système. Nous sommes en train de préparer le cauchemar pour les développeurs de ces autres classes. + </p> + <p> + A la place, voici la méthode complète pour le test avec un peu de magie via les objets fantaisie... +<pre> +Mock::generate('Session'); +Mock::generate('SessionPool'); +Mock::generate('Log'); + +class LoggingSessionPoolTest extends UnitTestCase { + ... + function testFindSessionLogging() {<strong> + $session = &new MockSession($this); + $pool = &new MockSessionPool($this); + $pool->setReturnReference('findSession', $session); + $pool->expectOnce('findSession', array('abc')); + + $log = &new MockLog($this); + $log->expectOnce('message', array('Starting session abc')); + + $logging_pool = &new LoggingSessionPool($pool, $log); + $this->assertReference($logging_pool->findSession('abc'), $session); + $pool->tally(); + $log->tally();</strong> + } +} +</pre> + Commençons par écrire une session simulacre. Pas la peine d'être trop pointilleux avec celle-ci puisque la vérification de la session désirée est effectuée ailleurs. Nous avons juste besoin de vérifier qu'il s'agit de la même que celle qui vient du groupe commun des sessions. + </p> + <p> + <span class="new_code">findSession()</span> est un méthode fabrique dont la simulation est décrite <a href="#stub">plus haut</a>. Le point de départ vient avec le premier appel <span class="new_code">expectOnce()</span>. Cette ligne indique qu'à chaque fois que <span class="new_code">findSession()</span> est invoqué sur l'objet fantaisie, il vérifiera les arguments entrant. S'il ne reçoit que la chaîne "abc" en tant qu'argument alors un succès est envoyé au testeur unitaire, sinon c'est un échec qui est généré. Il s'agit là de la partie qui teste si nous avons bien la bonne session. La liste des arguments suit une format identique à celui qui précise les valeurs renvoyées. Vous pouvez avoir des jokers et des séquences et l'ordre de l'évaluation restera le même. + </p> + <p> + Si l'appel n'est jamais effectué alors n'est généré ni le succès, ni l'échec. Pour contourner cette limitation, nous devons dire à l'objet fantaisie que le test est terminé : il pourra alors décider si les attentes ont été répondues. L'assertion du testeur unitaire de ceci est déclenchée par l'appel <span class="new_code">tally()</span> à la fin du test. + </p> + <p> + Nous utilisons le même modèle pour mettre sur pied le loggueur fantaisie. Nous lui indiquons que <span class="new_code">message()</span> devrait être invoqué une fois et une fois seulement avec l'argument "Starting session abc". En testant les arguments d'appel, plutôt que ceux de sorite du loggueur, nous isolons le test de tout modification dans le loggueur. + </p> + <p> + Nous commençons le lancement nos tests à la création du nouveau <span class="new_code">LoggingSessionPool</span> et nous l'alimentons avec nos objets fantaisie juste créés. Désormais tout est sous contrôle. Au final nous confirmons que le <span class="new_code">$session</span> donné au décorateur est bien celui reçu et prions les objets fantaisie de lancer leurs tests de comptage d'appel interne avec les appels <span class="new_code">tally()</span>. + </p> + <p> + Il y a encore pas mal de code de test, mais ce code est très strict. S'il vous semble encore terrifiant il l'est bien moins que si nous avions essayé sans les objets fantaisie et ce test en particulier, interactions plutôt que résultat, est toujours plus difficile à mettre en place. Le plus souvent vous aurez besoin de tester des situations plus complexes sans ce niveau ni cette précision. En outre une partie peut être remaniée avec la méthode de scénario de test <span class="new_code">setUp()</span>. + </p> + <p> + Voici la liste complète des attentes que vous pouvez placer sur un objet fantaisie avec <a href="http://www.lastcraft.com/simple_test.php">SimpleTest</a>... + <table> +<thead> + <tr> +<th>Attente</th><th>Nécessite <span class="new_code">tally()</span></th> +</tr> + </thead> +<tbody> +<tr> + <td><span class="new_code">expectArguments($method, $args)</span></td> + <td style="text-align: center">Non</td> + </tr> + <tr> + <td><span class="new_code">expectArgumentsAt($timing, $method, $args)</span></td> + <td style="text-align: center">Non</td> + </tr> + <tr> + <td><span class="new_code">expectCallCount($method, $count)</span></td> + <td style="text-align: center">Oui</td> + </tr> + <tr> + <td><span class="new_code">expectMaximumCallCount($method, $count)</span></td> + <td style="text-align: center">Non</td> + </tr> + <tr> + <td><span class="new_code">expectMinimumCallCount($method, $count)</span></td> + <td style="text-align: center">Oui</td> + </tr> + <tr> + <td><span class="new_code">expectNever($method)</span></td> + <td style="text-align: center">Non</td> + </tr> + <tr> + <td><span class="new_code">expectOnce($method, $args)</span></td> + <td style="text-align: center">Oui</td> + </tr> + <tr> + <td><span class="new_code">expectAtLeastOnce($method, $args)</span></td> + <td style="text-align: center">Oui</td> + </tr> + </tbody> +</table> + Où les paramètres sont... + <dl> + <dt class="new_code">$method</dt> + <dd>Le nom de la méthode, sous la forme d'une chaîne, à laquelle la condition doit être appliquée.</dd> + <dt class="new_code">$args</dt> + <dd> + Les arguments sous la forme d'une liste.

Elle reste silencieuse si la limite n'est jamais atteinte. + </p> + <p> + Comme avec les assertions dans les scénarios de test, toutes ces attentes peuvent accepter une surcharge de message sous la forme d'un paramètre supplémentaire. Par ailleurs le message d'échec original peut être inclus dans le résultat avec "%s". + </p> + + <p> +<a class="target" name="approches"> +<h2>D'autres approches</h2> +</a> +</p> + <p> + Il existe trois approches pour créer des objets fantaisie en comprenant celle utiliser par SimpleTest. Les coder à la main en utilisant une classe de base, les générer dans un fichier ou les générer dynamiquement à la volée. + </p> + <p> + Les objets fantaisie générés avec <a href="simple_test.html">SimpleTest</a> sont dynamiques. Ils sont créés à l'exécution dans la mémoire, grâce à <span class="new_code">eval()</span>, plutôt qu'écrit dans un fichier. Cette opération les rend facile à créer, en une seule ligne, surtout par rapport à leur création à la main dans une hiérarchie de classe parallèle. Le problème avec ce comportement tient généralement dans la mise en place des tests proprement dits. Si les objets originaux changent les versions fantaisie sur lesquels reposent les tests, une désynchronisation peut subvenir. Cela peut aussi arriver avec l'approche en hiérarchie parallèle, mais c'est détecté beaucoup plus vite. + </p> + <p> + Bien sûr, la solution est d'ajouter de véritables tests d'intégration. Vous n'en avez pas besoin de beaucoup et le côté pratique des objets fantaisie fait plus que compenser la petite dose de test supplémentaire. Vous ne pouvez pas avoir confiance dans du code qui ne serait testé que par des objets fantaisie. + </p> + <p> + Si vous restez déterminé de construire des librairies statiques d'objets fantaisie parce que vous souhaitez émuler un comportement très spécifique, vous pouvez y parvenir grâce au générateur de classe de SimpleTest. Dans votre fichier librairie, par exemple <em>mocks/connection.php</em> pour une connexion à une base de données, créer un objet fantaisie et provoquer m'héritage pour hériter pour surcharger des méthodes spéciales ou ajouter des préréglages... +<pre> +<?php + require_once('simpletest/mock_objects.php'); + require_once('../classes/connection.php'); +<strong> + Mock::generate('Connection', 'BasicMockConnection'); + class MockConnection extends BasicMockConnection { + function MockConnection(&$test, $wildcard = '*') { + $this->BasicMockConnection($test, $wildcard); + $this->setReturn('query', false); + } + }</strong> +?> +</pre> + L'appel <span class="new_code">generate</span> dit au générateur de classe d'en créer une appelée <span class="new_code">BasicMockConnection</span> plutôt que la plus courante <span class="new_code">MockConnection</span>. Ensuite nous héritons à partir de celle-ci pour obtenir notre version de <span class="new_code">MockConnection</span>. En interceptant de cette manière nous pouvons ajouter un comportement, ici transformer la valeur par défaut de <span class="new_code">query()</span> en "false". + En utilisant le nom par défaut nous garantissons que le générateur de classe fantaisie n'en recréera pas une autre différente si il est invoqué ailleurs dans les tests. Il ne créera jamais de classe si elle existe déjà. Aussi longtemps que le fichier ci-dessus est inclus avant alors tous les tests qui généraient <span class="new_code">MockConnection</span> devraient utiliser notre version à présent. Par contre si nous avons une erreur dans l'ordre et que la librairie de fantaisie en crée une d'abord alors la création de la classe échouera tout simplement. + </p> + <p> + Utiliser cette astuce si vous vous trouvez avec beaucoup de comportement en commun sur les objets fantaisie ou si vous avez de fréquents problèmes d'intégration plus tard dans les étapes de test. + </p> + + <p> +<a class="target" name="autres_testeurs"> +<h2>Je pense que SimpleTest pue !</h2> +</a> +</p> + <p> + Mais au moment d'écrire ces lignes c'est le seul à gérer les objets fantaisie, donc vous êtes bloqué avec lui ? + </p> + <p> + Non, pas du tout. + <a href="simple_test.html">SimpleTest</a> est une boîte à outils et parmi ceux-ci on trouve les objets fantaisie qui peuvent être utilisés indépendamment. Supposons que vous avez votre propre testeur unitaire favori et que tous vos tests actuels l'utilisent. Prétendez que vous avez appelé votre tester unitaire PHPUnit (c'est ce que tout le monde a fait) et que la classe principale de test ressemble à... +<pre> +class PHPUnit { + function PHPUnit() { + } + + function assertion($message, $assertion) { + } + ... +} +</pre> + La seule chose que la méthode <span class="new_code">assertion()</span> réalise, c'est de préparer une sortie embellie alors le paramètre boolien de l'assertion sert à déterminer s'il s'agit d'une erreur ou d'un succès. Supposons qu'elle est utilisée de la manière suivante... +<pre> +$unit_test = new PHPUnit(); +$unit_test>assertion('I hope this file exists', file_exists('my_file')); +</pre> + Comment utiliser les objets fantaisie avec ceci ? + </p> + <p> + Il y a une méthode protégée sur la classe de base des objets fantaisie : elle s'appelle <span class="new_code">_assertTrue()</span>. En surchargeant cette méthode nous pouvons utiliser notre propre format d'assertion. Nous commençons avec une sous-classe, dans <em>my_mock.php</em>... +<pre> +<strong><?php + require_once('simpletest/mock_objects.php'); + + class MyMock extends SimpleMock() { + function MyMock(&$test, $wildcard) { + $this->SimpleMock($test, $wildcard); + } + + function _assertTrue($assertion, $message) { + $test = &$this->getTest(); + $test->assertion($message, $assertion); + } + } +?></strong> +</pre> + Maintenant une instance de <span class="new_code">MyMock</span> créera un objet qui parle le même langage que votre testeur. Bien sûr le truc c'est que nous créons jamais un tel objet : le générateur s'en chargera. Nous avons juste besoin d'une ligne de code supplémentaire pour dire au générateur d'utiliser vos nouveaux objets fantaisie... +<pre> +<?php + require_once('simpletst/mock_objects.php'); + + class MyMock extends SimpleMock() { + function MyMock($test, $wildcard) { + $this->SimpleMock(&$test, $wildcard); + } + + function _assertTrue($assertion, $message , &$test) { + $test->assertion($message, $assertion); + } + }<strong> + SimpleTestOptions::setMockBaseClass('MyMock');</strong> +?> +</pre> + A partir de maintenant vous avez juste à inclure <em>my_mock.php</em> à la place de la version par défaut <em>simple_mock.php</em> et vous pouvez introduire des objets fantaisie dans votre suite de tests existants. + </p> + + </div> +<div class="copyright"> + Copyright<br>Marcus Baker, Jason Sweat, Perrick Penet 2004 + </div> +</body> +</html> diff --git a/tests/test_tools/simpletest/docs/fr/overview.html b/tests/test_tools/simpletest/docs/fr/overview.html new file mode 100755 index 00000000..b6965753 --- /dev/null +++ b/tests/test_tools/simpletest/docs/fr/overview.html @@ -0,0 +1,294 @@ +<html> +<head> +<META http-equiv="Content-Type" content="text/html; charset=UTF-8"> +<title> + Aperçu et liste des fonctionnalités des testeurs unitaires PHP et web de SimpleTest PHP + </title> +<link rel="stylesheet" type="text/css" href="docs.css" title="Styles"> +</head> +<body> +<div class="menu_back"> +<div class="menu"> +<h2> +<a href="index.html">SimpleTest</a> +</h2> +<ul> +<li> +<a href="overview.html">Overview</a> +</li> +<li> +<a href="unit_test_documentation.html">Unit tester</a> +</li> +<li> +<a href="group_test_documentation.html">Group tests</a> +</li> +<li> +<a href="server_stubs_documentation.html">Server stubs</a> +</li> +<li> +<a href="mock_objects_documentation.html">Mock objects</a> +</li> +<li> +<a href="partial_mocks_documentation.html">Partial mocks</a> +</li> +<li> +<a href="reporter_documentation.html">Reporting</a> +</li> +<li> +<a href="expectation_documentation.html">Expectations</a> +</li> +<li> +<a href="web_tester_documentation.html">Web tester</a> +</li> +<li> +<a href="form_testing_documentation.html">Testing forms</a> +</li> +<li> +<a href="authentication_documentation.html">Authentication</a> +</li> +<li> +<a href="browser_documentation.html">Scriptable browser</a> +</li> +</ul> +</div> +</div> +<h1>Apercu de SimpleTest</h1> +<div class="content"> + <p> +<a class="target" name="resume"> +<h2>Qu'est-ce que SimpleTest ?</h2> +</a> +</p> + <p> + Le coeur de SimpleTest est un framework de test construit autour de classes de scénarios de test. Celles-ci sont écrites comme des extensions des classes premières de scénarios de test, chacune élargie avec des méthodes qui contiennent le code de test effectif. Les scripts de test de haut niveau invoque la méthode <span class="new_code">run()</span> à chaque scénario de test successivement. Chaque méthode de test est écrite pour appeler des assertions diverses que le développeur suppose être vraies, <span class="new_code">assertEqual()</span> par exemple. Si l'assertion est correcte, alors un succès est expédié au rapporteur observant le test, mais toute erreur déclenche une alerte et une description de la dissension. + </p> + <p> + Un <a href="unit_test_documentation.html">scénario de test</a> ressemble à... +<pre> +class <strong>MyTestCase</strong> extends UnitTestCase { + <strong> + function testLog() { + $log = &new Log('my.log'); + $log->message('Hello'); + $this->assertTrue(file_exists('my.log')); + }</strong> +} +</pre> + </p> + <p> + Ces outils sont conçus pour le développeur. Les tests sont écrits en PHP directement, plus ou moins simultanément avec la construction de l'application elle-même. L'avantage d'utiliser PHP lui-même comme langage de test est qu'il n'y a pas de nouveau langage à apprendre, les tests peuvent commencer directement et le développeur peut tester n'importe quelle partie du code. Plus simplement, toutes les parties qui peuvent être accédées par le code de l'application peuvent aussi être accédées par le code de test si ils sont tous les deux dans le même langage. + </p> + <p> + Le type de scénario de test le plus simple est le <span class="new_code">UnitTestCase</span>. Cette classe de scénario de test inclut les tests standards pour l'égalité, les références et l'appariement de motifs (via les expressions rationnelles). Ceux-ci testent ce que vous seriez en droit d'attendre du résultat d'une fonction ou d'une méthode. Il s'agit du type de test le plus commun pendant le quotidien du développeur, peut-être 95% des scénarios de test. + </p> + <p> + La tâche ultime d'une application web n'est cependant pas de produire une sortie correcte à partir de méthodes ou d'objets, mais plutôt de produire des pages web. La classe <span class="new_code">WebTestCase</span> teste des pages web. Elle simule un navigateur web demandant une page, de façon exhaustive : cookies, proxies, connexions sécurisées, authentification, formulaires, cadres et la plupart des éléments de navigation. Avec ce type de scénario de test, le développeur peut garantir que telle ou telle information est présente dans la page et que les formulaires ainsi que les sessions sont gérés comme il faut. + </p> + <p> + Un <a href="web_tester_documentation.html">scénario de test web</a> ressemble à... +<pre> +class <strong>MySiteTest</strong> extends WebTestCase { + <strong> + function testHomePage() { + $this->get('http://www.my-site.com/index.php'); + $this->assertTitle('My Home Page'); + $this->clickLink('Contact'); + $this->assertTitle('Contact me'); + $this->assertWantedPattern('/Email me at/'); + }</strong> +} +</pre> + </p> + + <p> +<a class="target" name="fonctionnalites"> +<h2>Liste des fonctionnalites</h2> +</a> +</p> + <p> + Ci-dessous vous trouverez un canevas assez brut des fonctionnalités à aujourd'hui et pour demain, sans oublier leur date approximative de publication.

Le type de procédure que fait un usage le plus intensif des outils de test pour développeur est bien sûr l'<a href="http://www.extremeprogramming.org/">Extreme Programming</a>. Il s'agit là d'une des <a href="http://www.agilealliance.com/articles/index">méthodes agiles</a> qui combinent plusieurs pratiques pour "lisser la courbe de coût" du développement logiciel. La plus extrème reste le <a href="http://www.testdriven.com/modules/news/">développement piloté par les tests</a>, où vous devez adhérer à la règle du <cite>pas de code avant d'avoir un test</cite>. Si vous êtes plutôt du genre planninficateur ou que vous estimez que l'expérience compte plus que l'évolution, vous préférerez peut-être l'approche <a href="http://www.therationaledge.com/content/dec_01/f_spiritOfTheRUP_pk.html">RUP</a>. Je ne l'ai pas testé mais je peux voir où vous aurez besoin d'outils de test (cf. illustration 9). + </p> + <p> + La plupart des testeurs unitaires sont dans une certaine mesure un clone de <a href="http://www.junit.org/">JUnit</a>, au moins dans l'interface. Il y a énormément d'information sur le site de JUnit, à commencer par la <a href="http://junit.sourceforge.net/doc/faq/faq.htm">FAQ</a> quie contient pas mal de conseils généraux sur les tests. Une fois mordu par le bogue vous apprécierez sûrement la phrase <a href="http://junit.sourceforge.net/doc/testinfected/testing.htm">infecté par les tests</a> trouvée par Eric Gamma. Si vous êtes encore en train de tergiverser sur un testeur unitaire, sachez que les choix principaux sont <a href="http://phpunit.sourceforge.net/">PHPUnit</a> et <a href="http://pear.php.net/manual/en/package.php.phpunit.php">Pear PHP::PHPUnit</a>. De nombreuses fonctionnalités de SimpleTest leurs font défaut, mais la version PEAR a d'ores et déjà été mise à jour pour PHP5. Elle est aussi recommandée si vous portez des scénarios de test existant depuis <a href="http://www.junit.org/">JUnit</a>. + </p> + <p> + Les développeurs de bibliothèque n'ont pas l'air de livrer très souvent des tests avec leur code : c'est bien dommage. Le code d'une bibliothèque qui inclut des tests peut être remanié avec plus de sécurité et le code de test sert de documentation additionnelle dans un format assez standard. Ceci peut épargner la pêche aux indices dans le code source lorsque qu'un problème survient, en particulier lors de la mise à jour d'une telle bibliothèque. Parmi les bibliothèques utilisant SimpleTest comme testeur unitaire on retrouve <a href="http://wact.sourceforge.net/">WACT</a> et <a href="http://sourceforge.net/projects/htmlsax">PEAR::XML_HTMLSax</a>. + </p> + <p> + Au jour d'aujourd'hui il manque tristement beaucoup de matière sur les objets fantaisie : dommage, surtout que tester unitairement sans eux représente pas mal de travail en plus. L'<a href="http://www.sidewize.com/company/mockobjects.pdf">article original sur les objets fantaisie</a> est très orienté Java, mais reste intéressant à lire. Etant donné qu'il s'agit d'une nouvelle technologie il y a beaucoup de discussions et de débats sur comment les utiliser, souvent sur des wikis comme <a href="http://xpdeveloper.com/cgi-bin/oldwiki.cgi?MockObjects">Extreme Tuesday</a> ou <a href="http://www.mockobjects.com/wiki/MocksObjectsPaper">www.mockobjects.com</a>ou <a href="http://c2.com/cgi/wiki?MockObject">the original C2 Wiki</a>. Injecter des objets fantaisie dans une classe est un des champs principaux du débat : cet <a href="http://www-106.ibm.com/developerworks/java/library/j-mocktest.html">article chez IBM</a> en est un bon point de départ. + </p> + <p> + Il y a énormement d'outils de test web mais la plupart sont écrits en Java. De plus les tutoriels et autres conseils sont plutôt rares. Votre seul espoir est de regarder directement la documentation pour <a href="http://httpunit.sourceforge.net/">HTTPUnit</a>, <a href="http://htmlunit.sourceforge.net/">HTMLUnit</a> ou <a href="http://jwebunit.sourceforge.net/">JWebUnit</a> et d'espérer y trouver pour des indices. Il y a aussi des frameworks basés sur XML, mais de nouveau la plupart ont besoin de Java pour tourner. + </p> + + </div> +<div class="copyright"> + Copyright<br>Marcus Baker, Jason Sweat, Perrick Penet 2004 + </div> +</body> +</html> diff --git a/tests/test_tools/simpletest/docs/fr/partial_mocks_documentation.html b/tests/test_tools/simpletest/docs/fr/partial_mocks_documentation.html new file mode 100755 index 00000000..4098ab45 --- /dev/null +++ b/tests/test_tools/simpletest/docs/fr/partial_mocks_documentation.html @@ -0,0 +1,333 @@ +<html> +<head> +<META http-equiv="Content-Type" content="text/html; charset=UTF-8"> +<title>Documentation SimpleTest : les objets fantaisie partiels</title> +<link rel="stylesheet" type="text/css" href="docs.css" title="Styles"> +</head> +<body> +<div class="menu_back"> +<div class="menu"> +<h2> +<a href="index.html">SimpleTest</a> +</h2> +<ul> +<li> +<a href="overview.html">Overview</a> +</li> +<li> +<a href="unit_test_documentation.html">Unit tester</a> +</li> +<li> +<a href="group_test_documentation.html">Group tests</a> +</li> +<li> +<a href="server_stubs_documentation.html">Server stubs</a> +</li> +<li> +<a href="mock_objects_documentation.html">Mock objects</a> +</li> +<li> +<a href="partial_mocks_documentation.html">Partial mocks</a> +</li> +<li> +<a href="reporter_documentation.html">Reporting</a> +</li> +<li> +<a href="expectation_documentation.html">Expectations</a> +</li> +<li> +<a href="web_tester_documentation.html">Web tester</a> +</li> +<li> +<a href="form_testing_documentation.html">Testing forms</a> +</li> +<li> +<a href="authentication_documentation.html">Authentication</a> +</li> +<li> +<a href="browser_documentation.html">Scriptable browser</a> +</li> +</ul> +</div> +</div> +<h1>Documentation sur les objets fantaisie partiels</h1> +<div class="content"> + + <p> + Un objet fantaisie partiel n'est ni plus ni moins qu'un modèle de conception pour soulager un problème spécifique du test avec des objets fantaisie, celui de placer des objets fantaisie dans des coins serrés. Il s'agit d'un outil assez limité et peut-être même une idée pas si bonne que ça. Elle est incluse dans SimpleTest pour la simple raison que je l'ai trouvée utile à plus d'une occasion et qu'elle m'a épargnée pas mal de travail dans ces moments-là. + </p> + + <p> +<a class="target" name="injection"> +<h2>Le problème de l'injection dans un objet fantaisie</h2> +</a> +</p> + <p> + Quand un objet en utilise un autre il est très simple d'y faire circuler une version fantaisie déjà prête avec ses attentes. Les choses deviennent un peu plus délicates si un objet en crée un autre et que le créateur est celui que l'on souhaite tester. Cela revient à dire que l'objet créé devrait être une fantaisie, mais nous pouvons difficilement dire à notre classe sous test de créer un objet fantaisie plutôt qu'un "vrai" objet. La classe testée ne sait même pas qu'elle travaille dans un environnement de test. + </p> + <p> + Par exemple, supposons que nous sommes en train de construire un client telnet et qu'il a besoin de créer une socket réseau pour envoyer ses messages. La méthode de connexion pourrait ressemble à quelque chose comme... +<pre> +<strong><?php + require_once('socket.php'); + + class Telnet { + ... + function &connect($ip, $port, $username, $password) { + $socket = &new Socket($ip, $port); + $socket->read( ... ); + ... + } + } +?></strong> +</pre> + Nous voudrions vraiment avoir une version fantaisie de l'objet socket, que pouvons nous faire ? + </p> + <p> + La première solution est de passer la socket en tant que paramètre, ce qui force la création au niveau inférieur. Charger le client de cette tâche est effectivement une bonne approche si c'est possible et devrait conduire à un remaniement -- de la création à partir de l'action. En fait, c'est là une des manières avec lesquels tester en s'appuyant sur des objets fantaisie vous force à coder des solutions plus resserrées sur leur objectif. Ils améliorent votre programmation. + </p> + <p> + Voici ce que ça devrait être... +<pre> +<?php + require_once('socket.php'); + + class Telnet { + ... + <strong>function &connect(&$socket, $username, $password) { + $socket->read( ... ); + ... + }</strong> + } +?> +</pre> + Sous-entendu, votre code de test est typique d'un cas de test avec un objet fantaisie. +<pre> +class TelnetTest extends UnitTestCase { + ... + function testConnection() {<strong> + $socket = &new MockSocket($this); + ... + $telnet = &new Telnet(); + $telnet->connect($socket, 'Me', 'Secret'); + ...</strong> + } +} +</pre> + C'est assez évident que vous ne pouvez descendre que d'un niveau. Vous ne voudriez pas que votre application de haut niveau crée tous les fichiers de bas niveau, sockets et autres connexions à la base de données dont elle aurait besoin. Elle ne connaîtrait pas les paramètres du constructeur de toute façon. + </p> + <p> + La solution suivante est de passer l'objet créé sous la forme d'un paramètre optionnel... +<pre> +<?php + require_once('socket.php'); + + class Telnet { + ...<strong> + function &connect($ip, $port, $username, $password, $socket = false) { + if (!$socket) { + $socket = &new Socket($ip, $port); + } + $socket->read( ... );</strong> + ... + return $socket; + } + } +?> +</pre> + Pour une solution rapide, c'est généralement suffisant. Ensuite le test est très similaire : comme si le paramètre était transmis formellement... +<pre> +class TelnetTest extends UnitTestCase { + ... + function testConnection() {<strong> + $socket = &new MockSocket($this); + ... + $telnet = &new Telnet(); + $telnet->connect('127.0.0.1', 21, 'Me', 'Secret', &$socket); + ...</strong> + } +} +</pre> + Le problème de cette approche tient dans son manque de netteté. Il y a du code de test dans la classe principale et aussi des paramètres transmis dans le scénario de test qui ne sont jamais utilisés. Il s'agit là d'une approche rapide et sale, mais qui ne reste pas moins efficace dans la plupart des situations. + </p> + <p> + Une autre solution encore est de laisser un objet fabrique s'occuper de la création... +<pre> +<?php + require_once('socket.php'); + + class Telnet {<strong> + function Telnet(&$network) { + $this->_network = &$network; + }</strong> + ... + function &connect($ip, $port, $username, $password) {<strong> + $socket = &$this->_network->createSocket($ip, $port); + $socket->read( ... );</strong> + ... + return $socket; + } + } +?> +</pre> + Il s'agit là probablement de la réponse la plus travaillée étant donné que la création est maintenant située dans une petite classe spécialisée. La fabrique réseau peut être testée séparément et utilisée en tant que fantaisie quand nous testons la classe telnet... +<pre> +class TelnetTest extends UnitTestCase { + ... + function testConnection() {<strong> + $socket = &new MockSocket($this); + ... + $network = &new MockNetwork($this); + $network->setReturnReference('createSocket', $socket); + $telnet = &new Telnet($network); + $telnet->connect('127.0.0.1', 21, 'Me', 'Secret'); + ...</strong> + } +} +</pre> + Le problème reste que nous ajoutons beaucoup de classes à la bibliothèque. Et aussi que nous utilisons beaucoup de fabriques ce qui rend notre code un peu moins intuitif. La solution la plus flexible, mais aussi la plus complexe. + </p> + <p> + Peut-on trouver un juste milieu ? + </p> + + <p> +<a class="target" name="creation"> +<h2>Méthode fabrique protégée</h2> +</a> +</p> + <p> + Il existe une technique pour palier à ce problème sans créer de nouvelle classe dans l'application; par contre elle induit la création d'une sous-classe au moment du test. Premièrement nous déplaçons la création de la socket dans sa propre méthode... +<pre> +<?php + require_once('socket.php'); + + class Telnet { + ... + function &connect($ip, $port, $username, $password) {<strong> + $socket = &$this->_createSocket($ip, $port);</strong> + $socket->read( ... ); + ... + }<strong> + + function &_createSocket($ip, $port) { + return new Socket($ip, $port); + }</strong> + } +?> +</pre> + Il s'agit là de la seule modification dans le code de l'application. + </p> + <p> + Pour le scénario de test, nous devons créer une sous-classe de manière à intercepter la création de la socket... +<pre> +<strong>class TelnetTestVersion extends Telnet { + var $_mock; + + function TelnetTestVersion(&$mock) { + $this->_mock = &$mock; + $this->Telnet(); + } + + function &_createSocket() { + return $this->_mock; + } +}</strong> +</pre> + Ici j'ai déplacé la fantaisie dans le constructeur, mais un setter aurait fonctionné tout aussi bien. Notez bien que la fantaisie est placée dans une variable d'objet avant que le constructeur ne soit attaché. C'est nécessaire dans le cas où le constructeur appelle <span class="new_code">connect()</span>. Autrement il pourrait donner un valeur nulle à partir de <span class="new_code">_createSocket()</span>. + </p> + <p> + Après la réalisation de tout ce travail supplémentaire le scénario de test est assez simple. Nous avons juste besoin de tester notre nouvelle classe à la place... +<pre> +class TelnetTest extends UnitTestCase { + ... + function testConnection() {<strong> + $socket = &new MockSocket($this); + ... + $telnet = &new TelnetTestVersion($socket); + $telnet->connect('127.0.0.1', 21, 'Me', 'Secret'); + ...</strong> + } +} +</pre> + Cette nouvelle classe est très simple bien sûr. Elle ne fait qu'initier une valeur renvoyée, à la manière d'une fantaisie. Ce serait pas mal non plus si elle pouvait vérifier les paramètres entrants. Exactement comme un objet fantaisie. Il se pourrait bien que nous ayons à réaliser cette astuce régulièrement : serait-il possible d'automatiser la création de cette sous-classe ? + </p> + + <p> +<a class="target" name="partiel"> +<h2>Un objet fantaisie partiel</h2> +</a> +</p> + <p> + Bien sûr la réponse est "oui" ou alors j'aurais arrêté d'écrire depuis quelques temps déjà ! Le test précédent a représenté beaucoup de travail, mais nous pouvons générer la sous-classe en utilisant une approche à celle des objets fantaisie. + </p> + <p> + Voici donc une version avec objet fantaisie partiel du test... +<pre> +<strong>Mock::generatePartial( + 'Telnet', + 'TelnetTestVersion', + array('_createSocket'));</strong> + +class TelnetTest extends UnitTestCase { + ... + function testConnection() {<strong> + $socket = &new MockSocket($this); + ... + $telnet = &new TelnetTestVersion($this); + $telnet->setReturnReference('_createSocket', $socket); + $telnet->Telnet(); + $telnet->connect('127.0.0.1', 21, 'Me', 'Secret'); + ...</strong> + } +} +</pre> + La fantaisie partielle est une sous-classe de l'original dont on aurait "remplacé" les méthodes sélectionnées avec des versions de test. L'appel à <span class="new_code">generatePartial()</span> nécessite trois paramètres : la classe à sous classer, le nom de la nouvelle classe et une liste des méthodes à simuler. + </p> + <p> + Instancier les objets qui en résultent est plutôt délicat. L'unique paramètre du constructeur d'un objet fantaisie partiel est la référence du testeur unitaire. Comme avec les objets fantaisie classiques c'est nécessaire pour l'envoi des résultats de test en réponse à la vérification des attentes. + </p> + <p> + Une nouvelle fois le constructeur original n'est pas lancé. Indispensable dans le cas où le constructeur aurait besoin des méthodes fantaisie : elles n'ont pas encore été initiées ! Nous initions les valeurs retournées à cet instant et ensuite lançons le constructeur avec ses paramètres normaux. Cette construction en trois étapes de "new", suivie par la mise en place des méthodes et ensuite par la lancement du constructeur proprement dit est ce qui distingue le code d'un objet fantaisie partiel. + </p> + <p> + A part pour leur construction, toutes ces méthodes fantaisie ont les mêmes fonctionnalités que dans le cas des objets fantaisie et toutes les méthodes non fantaisie se comportent comme avant. Nous pouvons mettre en place des attentes très facilement... +<pre> +class TelnetTest extends UnitTestCase { + ... + function testConnection() { + $socket = &new MockSocket($this); + ... + $telnet = &new TelnetTestVersion($this); + $telnet->setReturnReference('_createSocket', $socket);<strong> + $telnet->expectOnce('_createSocket', array('127.0.0.1', 21));</strong> + $telnet->Telnet(); + $telnet->connect('127.0.0.1', 21, 'Me', 'Secret'); + ...<strong> + $telnet->tally();</strong> + } +} +</pre> + </p> + + <p> +<a class="target" name="moins"> +<h2>Tester moins qu'une classe</h2> +</a> +</p> + <p> + Les méthodes issues d'un objet fantaisie n'ont pas besoin d'être des méthodes fabrique, Il peut s'agir de n'importe quelle sorte de méthode. Ainsi les objets fantaisie partiels nous permettent de prendre le contrôle de n'importe quelle partie d'une classe, le constructeur excepté. Nous pourrions même aller jusqu'à créer des fantaisies sur toutes les méthode à part celle que nous voulons effectivement tester. + </p> + <p> + Cette situation est assez hypothétique, étant donné que je ne l'ai jamais essayée. Je suis ouvert à cette possibilité, mais je crains qu'en forçant la granularité d'un objet on n'obtienne pas forcément un code de meilleur qualité. Personnellement j'utilise les objets fantaisie partiels comme moyen de passer outre la création ou alors de temps en temps pour tester le modèle de conception TemplateMethod. + </p> + <p> + Pour choisir le mécanisme à utiliser, on en revient toujours aux standards de code de votre projet. + </p> + + </div> +<div class="copyright"> + Copyright<br>Marcus Baker, Jason Sweat, Perrick Penet 2004 + </div> +</body> +</html> diff --git a/tests/test_tools/simpletest/docs/fr/reporter_documentation.html b/tests/test_tools/simpletest/docs/fr/reporter_documentation.html new file mode 100755 index 00000000..4f927781 --- /dev/null +++ b/tests/test_tools/simpletest/docs/fr/reporter_documentation.html @@ -0,0 +1,386 @@ +<html> +<head> +<META http-equiv="Content-Type" content="text/html; charset=UTF-8"> +<title>Documentation SimpleTest : le rapporteur de test</title> +<link rel="stylesheet" type="text/css" href="docs.css" title="Styles"> +</head> +<body> +<div class="menu_back"> +<div class="menu"> +<h2> +<a href="index.html">SimpleTest</a> +</h2> +<ul> +<li> +<a href="overview.html">Overview</a> +</li> +<li> +<a href="unit_test_documentation.html">Unit tester</a> +</li> +<li> +<a href="group_test_documentation.html">Group tests</a> +</li> +<li> +<a href="server_stubs_documentation.html">Server stubs</a> +</li> +<li> +<a href="mock_objects_documentation.html">Mock objects</a> +</li> +<li> +<a href="partial_mocks_documentation.html">Partial mocks</a> +</li> +<li> +<a href="reporter_documentation.html">Reporting</a> +</li> +<li> +<a href="expectation_documentation.html">Expectations</a> +</li> +<li> +<a href="web_tester_documentation.html">Web tester</a> +</li> +<li> +<a href="form_testing_documentation.html">Testing forms</a> +</li> +<li> +<a href="authentication_documentation.html">Authentication</a> +</li> +<li> +<a href="browser_documentation.html">Scriptable browser</a> +</li> +</ul> +</div> +</div> +<h1>Documentation sur le rapporteur de test</h1> +<div class="content"> + + <p> + SimpleTest suit plutôt plus que moins le modèle MVC (Modèle-Vue-Contrôleur).

Premièrement les méthodes d'affichage que vous voudrez probablement surcharger... + <ul class="api"> + <li> + <span class="new_code">HtmlReporter(string $encoding)</span> +<br> + est le constructeur. Notez que le test unitaire initie le lien à l'affichage plutôt que l'opposé. L'affichage est principalement un receveur passif des évènements de tests. Cela permet d'adapter facilement l'affichage pour d'autres systèmes en dehors des tests unitaires, tel le suivi de la charge de serveurs. L'"encoding" est le type d'encodage que vous souhaitez utiliser pour l'affichage du test. Pour pouvoir effectuer un rendu correct de la sortie de débogage quand on utilise le testeur web, il doit correspondre à l'encodage du site testé. Les chaînes de caractères disponibles sont indiquées dans la fonction PHP <a href="http://www.php.net/manual/fr/function.htmlentities.php">html_entities()</a>. + </li> + <li> + <span class="new_code">void paintHeader(string $test_name)</span> +<br> + est appelé une fois, au début du test quand l'évènement de démarrage survient. Le premier évènement de démarrage est souvent délivré par le groupe de test du niveau le plus haut et donc c'est de là que le <span class="new_code">$test_name</span> arrive. Il peint les titres de la page, CSS, la balise "body", etc. Il ne renvoie rien du tout (<span class="new_code">void</span>). + </li> + <li> + <span class="new_code">void paintFooter(string $test_name)</span> +<br> + est appelé à la toute fin du test pour fermer les balises ouvertes par l'entête de la page. Par défaut il affiche aussi la barre rouge ou verte et le décompte final des résultats. En fait la fin des tests arrive quand l'évènement de fin de test arrive avec le même nom que celui qui l'a initié au même niveau. Le nid des tests en quelque sorte. Fermer le dernier test finit l'affichage. + </li> + <li> + <span class="new_code">void paintMethodStart(string $test_name)</span> +<br> + est appelé au début de chaque méthode de test. Normalement le nom vient de celui de la méthode. Les autres évènements de départ de test se comportent de la même manière sauf que celui du groupe de test indique au rapporteur le nombre de scénarios de test qu'il contient. De la sorte le rapporteur peut afficher une barre de progrès au fur et à mesure que l'exécuteur passe en revue les scénarios de test. + </li> + <li> + <span class="new_code">void paintMethodEnd(string $test_name)</span> +<br> + clôt le test lancé avec le même nom. + </li> + <li> + <span class="new_code">void paintFail(string $message)</span> +<br> + peint un échec. Par défait il ne fait qu'afficher le mot "fail", une trace d'arborescence affichant la position du test en cours et le message transmis par l'assertion. + </li> + <li> + <span class="new_code">void paintPass(string $message)</span> +<br> + ne fait rien, par défaut. + </li> + <li> + <span class="new_code">string _getCss()</span> +<br> + renvoie les styles CSS sous la forme d'une chaîne à l'attention de la méthode d'entêtes d'une page. Des styles additionnels peuvent être ajoutés ici si vous ne surchargez pas les entêtes de la page. Vous ne voudrez pas utiliser cette méthode dans des entêtes d'une page surchargée si vous souhaitez inclure le feuille de style CSS d'origine. + </li> + </ul> + Il y a aussi des accesseurs pour aller chercher l'information sur l'état courant de la suite de test. Vous les utiliserez pour enrichir l'affichage... + <ul class="api"> + <li> + <span class="new_code">array getTestList()</span> +<br> + est la première méthode très commode pour les sous-classes. Elle liste l'arborescence courante des tests sous la forme d'une liste de noms de tests. Le premier test -- celui le plus proche du coeur -- sera le premier dans la liste et la méthode de test en cours sera la dernière. + </li> + <li> + <span class="new_code">integer getPassCount()</span> +<br> + renvoie le nombre de succès atteint. Il est nécessaire pour l'affichage à la fin. + </li> + <li> + <span class="new_code">integer getFailCount()</span> +<br> + renvoie de la même manière le nombre d'échecs. + </li> + <li> + <span class="new_code">integer getExceptionCount()</span> +<br> + renvoie quant à lui le nombre d'erreurs. + </li> + <li> + <span class="new_code">integer getTestCaseCount()</span> +<br> + est le nombre total de scénarios lors de l'exécution des tests. Il comprend aussi les tests groupés. + </li> + <li> + <span class="new_code">integer getTestCaseProgress()</span> +<br> + est le nombre de scénarios réalisés jusqu'à présent. + </li> + </ul> + Une modification simple : demander à l'HtmlReporter d'afficher aussi bien les succès que les échecs et les erreurs... +<pre> +<strong>class ShowPasses extends HtmlReporter { + + function paintPass($message) { + parent::paintPass($message); + print "&<span class=\"pass\">Pass</span>: "; + $breadcrumb = $this->getTestList(); + array_shift($breadcrumb); + print implode("-&gt;", $breadcrumb); + print "-&gt;$message<br />\n"; + } + + function _getCss() { + return parent::_getCss() . ' .pass { color: green; }'; + } +}</strong> +</pre> + </p> + <p> + Une méthode qui a beaucoup fait jaser reste la méthode <span class="new_code">makeDry()</span>. Si vous lancez cette méthode, sans paramètre, sur le rapporteur avant que la suite de test ne soit exécutée alors aucune méthode de test ne sera appelée. Vous continuerez à avoir les évènements entrants et sortants des méthodes et scénarios de test, mais aucun succès ni échec ou erreur, parce que le code de test ne sera pas exécuté. + </p> + <p> + La raison ? Pour permettre un affichage complexe d'une IHM (ou GUI) qui permettrait la sélection de scénarios de test individuels. Afin de construire une liste de tests possibles, ils ont besoin d'un rapport sur la structure du test pour, par exemple, l'affichage un vue en arbre de la suite de test. Avec un rapporteur lancé sur une exécution sèche qui ne renverrait que les évènements d'affichage, cela devient facilement réalisable. + </p> + + <p> +<a class="target" name="autre"> +<h2>Etendre le rapporteur</h2> +</a> +</p> + <p> + Plutôt que de modifier l'affichage existant, vous voudrez peut-être produire une présentation HTML complètement différente, ou même générer une version texte ou XML. Plutôt que de surcharger chaque méthode dans <span class="new_code">HtmlReporter</span> nous pouvons nous rendre une étape plus haut dans la hiérarchie de classe vers <span class="new_code">SimpleReporter</span> dans le fichier source <em>simple_test.php</em>. + </p> + <p> + Un affichage sans rien, un canvas vierge pour votre propre création, serait... +<pre> +<strong>require_once('simpletest/simple_test.php');</strong> + +class MyDisplay extends SimpleReporter {<strong> + </strong> + function paintHeader($test_name) { + } + + function paintFooter($test_name) { + } + + function paintStart($test_name, $size) {<strong> + parent::paintStart($test_name, $size);</strong> + } + + function paintEnd($test_name, $size) {<strong> + parent::paintEnd($test_name, $size);</strong> + } + + function paintPass($message) {<strong> + parent::paintPass($message);</strong> + } + + function paintFail($message) {<strong> + parent::paintFail($message);</strong> + } +} +</pre> + Aucune sortie ne viendrait de cette classe jusqu'à un ajout de votre part. + </p> + + <p> +<a class="target" name="cli"> +<h2>Le rapporteur en ligne de commande</h2> +</a> +</p> + <p> + SimpleTest est aussi livré avec un rapporteur en ligne de commande, minime lui aussi. L'interface imite celle de JUnit, sauf qu'elle envoie les messages d'erreur au fur et à mesure de leur arrivée.

Pour fonctionner comme il faut dans des scripts shell le script de test devrait renvoyer un code de sortie non-nul suite à un échec. Si une suite de test échoue la valeur <span class="new_code">false</span> est renvoyée par la méthode <span class="new_code">SimpleTest::run()</span>. Nous pouvons utiliser ce résultat pour terminer le script avec la bonne valeur renvoyée... +<pre> +<?php + require_once('simpletest/unit_tester.php'); + require_once('simpletest/reporter.php'); + + $test = &new GroupTest('File test'); + $test->addTestFile('tests/file_test.php'); + <strong>exit ($test->run(new TextReporter()) ? 0 : 1);</strong> +?> +</pre> + Bien sûr l'objectif n'est pas de créer deux scripts de test, l'un en ligne de commande et l'autre pour un navigateur web, pour chaque suite de test.

Un bouchon serveur est une simulation d'un objet ou d'un composant. Il doit remplacer exactement un composant dans un système pour des raisons de testabilité ou de prototypage, tout en restant léger. Il permet aux tests de tourner plus rapidement ou alors, si la classe simulée n'a pas été écrite, juste de fonctionner. + </p> + + <p> +<a class="target" name="creation"> +<h2>Créer des bouchons serveur</h2> +</a> +</p> + <p> + Nous avons juste besoin d'une classe préexistante, par exemple une connexion vers une base de données qui ressemblerait à... +<pre> +<strong>class DatabaseConnection { + function DatabaseConnection() { + } + + function query() { + } + + function selectQuery() { + } +}</strong> +</pre> + La classe n'a même pas encore besoin d'avoir été implémentée. Pour créer la version bouchonnée de cette classe, nous incluons la librairie de bouchon serveur et exécutons le générateur... +<pre> +<strong>require_once('simpletest/mock_objects.php'); +require_once('database_connection.php'); +Stub::generate('DatabaseConnection');</strong> +</pre> + Est généré un clone de la classe appelé <span class="new_code">StubDatabaseConnection</span>. Nous pouvons alors créer des instances de cette nouvelle classe à l'intérieur de notre prototype de script... +<pre> +require_once('simpletest/mock_objects.php'); +require_once('database_connection.php'); +Stub::generate('DatabaseConnection'); +<strong> +$connection = new StubDatabaseConnection(); +</strong> +</pre> + La version bouchonnée de la classe contient toutes les méthodes de l'original de telle sorte qu'une opération comme <span class="new_code">$connection->query()</span> soit encore légale. La valeur retournée sera <span class="new_code">null</span>, Mais nous pouvons y remédier avec... +<pre> +<strong>$connection->setReturnValue('query', 37)</strong> +</pre> + Désormais à chaque appel de <span class="new_code">$connection->query()</span> nous obtenons un résultat de 37. Nous pouvons choisir n'importe quelle valeur pour le résultat, par exemple un hash de résultats provenant d'un base de données imaginaire ou alors une liste d'objets persistants. Peu importe les paramètres, nous obtenons systématiquement les même valeurs chaque fois qu'ils ont été initialisés de la sorte : ça ne ressemble peut-être pas à une réponse convaincante venant d'une connexion vers une base de données. Mais pour la demi-douzaine de lignes d'une méthode de test c'est souvent largement suffisant. + </p> + + <p> +<a class="target" name="mod%C3%A8les"> +<h2>Modèles de simulation</h2> +</a> +</p> + <p> + Sauf que les choses ne sont que rarement aussi simples. Parmi les problèmes les plus courants on trouve les itérateurs : le renvoi d'une valeur constante peut causer une boucle infini dans l'objet testé. Pour ceux-ci nous avons besoin de mettre sur pied une suite de valeurs. Prenons par exemple un itérateur simple qui ressemble à... +<pre> +class Iterator { + function Iterator() { + } + + function next() { + } +} +</pre> + C'est probablement le plus simple des itérateurs possibles. Supposons que cet itérateur ne retourne que du texte, jusqu'à la fin - quand il retourne <span class="new_code">false</span>. Une simulation est possible avec... +<pre> +<strong>Stub::generate('Iterator'); + +$iterator = new StubIterator(); +$iterator->setReturnValue('next', false); +$iterator->setReturnValueAt(0, 'next', 'First string'); +$iterator->setReturnValueAt(1, 'next', 'Second string');</strong> +</pre> + A l'appel de <span class="new_code">next()</span> sur l'itérateur bouchonné il va d'abord renvoyer "First string", puis au second appel c'est "Second string" qui sera renvoyé. Finalement pour tous les autres appels, il s'agira d'un <span class="new_code">false</span>. Les valeurs renvoyées successivement ont priorité sur la valeur constante renvoyé. Cette dernière est un genre de valeur par défaut. + </p> + <p> + Une autre situation délicate est une opération <span class="new_code">get()</span> surchargée. Un exemple ? Un porteur d'information avec des pairs de clef / valeur. Prenons une classe de configuration... +<pre> +class Configuration { + function Configuration() { + } + + function getValue($key) { + } +} +</pre> + Il s'agit d'une situation propice à l'utilisation d'objets bouchon, surtout que la configuration en production dépend invariablement de la machine : l'utiliser directement ne va pas nous aider à maintenir notre confiance dans nos tests. Sauf que le problème tient de ce que toutes les données proviennent de la méthode <span class="new_code">getValue()</span> et que nous voulons des résultats différents suivant la clef. Par chance les bouchons ont un système de filtre... +<pre> +<strong>Stub::generate('Configuration'); + +$config = &new StubConfiguration(); +$config->setReturnValue('getValue', 'primary', array('db_host')); +$config->setReturnValue('getValue', 'admin', array('db_user')); +$config->setReturnValue('getValue', 'secret', array('db_password'));</strong> +</pre> + Ce paramètre supplémentaire est une liste d'arguments que l'on peut utiliser. Dans ce cas nous essayons d'utiliser un unique argument, à savoir la clef recherchée. Maintenant quand on invoque le bouchon serveur via la méthode <span class="new_code">getValue()</span> avec... +<pre> +$config->getValue('db_user'); +</pre> + ...il renvoie "admin". Il le trouve en essayant d'assortir successivement les arguments d'entrée avec sa liste de ceux de sortie jusqu'au moment où une correspondance exacte est trouvée. + </p> + <p> + Vous pouvez définir un argument par défaut avec... +<pre> +<strong> +$config->setReturnValue('getValue', false, array('*'));</strong> +</pre> + Attention ce n'est pas équivalent à initialiser la valeur retournée sans aucun argument. +<pre> +<strong> +$config->setReturnValue('getValue', false);</strong> +</pre> + Dans le premier cas il acceptera n'importe quel argument, mais exactement un -- pas plus -- est nécessaire. Dans le second cas n'importe quel nombre d'arguments fera l'affaire : il agit comme un <cite>catchall</cite> après tous les correspondances. Prenez garde à l'ordre : si nous ajoutons un autre paramètre après le joker ('*') il sera ignoré puisque le joker aura été trouvé auparavant. Avec des listes de paramètres complexes l'ordre peut devenir crucial, au risque de perdre des correspondances souhaitées, masquées par un joker antérieur. Pensez à mettre d'abord les cas les plus spécifiques si vous n'êtes pas sûr. + </p> + <p> + Il y a des fois où l'on souhaite qu'un objet spécifique soit servi par le bouchon plutôt qu'une simple copie. La sémantique de la copie en PHP nous force à utiliser une autre méthode pour cela. Vous êtes peut-être en train de simuler un conteneur par exemple... +<pre> +class Thing { +} + +class Vector { + function Vector() { + } + + function get($index) { + } +} +</pre> + Dans ce cas vous pouvez mettre une référence dans la liste renvoyée par le bouchon... +<pre> +Stub::generate('Vector'); + +$thing = new Thing();<strong> +$vector = &new StubVector(); +$vector->setReturnReference('get', $thing, array(12));</strong> +</pre> + Avec ce petit arrangement vous vous assurez qu'à chaque fois que <span class="new_code">$vector->get(12)</span> est appelé il renverra le même <span class="new_code">$thing</span>. + </p> + <p> + Ces trois facteurs, ordre, paramètres et copie (ou référence), peuvent être combinés orthogonalement. Par exemple... +<pre> +$complex = &new StubComplexThing(); +$stuff = new Stuff();<strong> +$complex->setReturnReferenceAt(3, 'get', $stuff, array('*', 1));</strong> +</pre> + Le <span class="new_code">$stuff</span> ne sera renvoyé qu'au troisième appel et seulement si deux paramètres étaient indiqués, avec la contrainte que le second de ceux-ci soit l'entier 1. N'est-ce pas suffisant pour des situations de prototypage simple ? + </p> + <p> + Un dernier cas critique reste celle d'un objet en créant un autre, connu sous le nom du modèle factory - fabrique. Supposons qu'après une requête réussie à notre base de données imaginaire, un ensemble de résultats est retourné sous la forme d'un itérateur, chaque appel à <span class="new_code">next()</span> donnant un ligne et à la fin un <span class="new_code">false</span>. + Au premier abord, ça donne l'impression d'être cauchemardesque à simuler. Alors qu'en fait tout peut être bouchonné en utilisant les mécanismes ci-dessus. + </p> + <p> + Voici comment... +<pre> +Stub::generate('DatabaseConnection'); +Stub::generate('ResultIterator'); + +class DatabaseTest extends UnitTestCase { + + function testUserFinder() {<strong> + $result = &new StubResultIterator(); + $result->setReturnValue('next', false); + $result->setReturnValueAt(0, 'next', array(1, 'tom')); + $result->setReturnValueAt(1, 'next', array(3, 'dick')); + $result->setReturnValueAt(2, 'next', array(6, 'harry')); + + $connection = &new StubDatabaseConnection(); + $connection->setReturnValue('query', false); + $connection->setReturnReference( + 'query', + $result, + array('select id, name from users'));</strong> + + $finder = &new UserFinder($connection); + $this->assertIdentical( + $finder->findNames(), + array('tom', 'dick', 'harry')); + } +} +</pre> + Désormais ce n'est que si notre <span class="new_code">$connection</span> est appelé avec la bonne <span class="new_code">query()</span> que le <span class="new_code">$result</span> sera renvoyé après le troisième appel à <span class="new_code">next()</span>. Cela devrait être suffisant pour que notre classe <span class="new_code">UserFinder</span>, la classe effectivement testée à ce niveau, puisse s'exécuter comme il faut. Un test très précis et pas une seule base de données à l'horizon. + </p> + + <p> +<a class="target" name="options"> +<h2>Options de création pour les bouchons</h2> +</a> +</p> + <p> + Il y a d'autres options additionnelles à la création d'un bouchon. Au moment de la génération nous pouvons changer le nom de la classe... +<pre> +<strong>Stub::generate('Iterator', 'MyStubIterator'); +$iterator = &new MyStubIterator(); +</strong> +</pre> + Pris tout seul ce n'est pas très utile étant donné qu'il n'y aurait pas de différence entre cette classe et celle par défaut -- à part le nom bien entendu. Par contre nous pouvons aussi lui ajouter d'autres méthodes qui ne se trouveraient pas dans l'interface originale... +<pre> +class Iterator { +} +<strong>Stub::generate('Iterator', 'PrototypeIterator', array('next', 'isError')); +$iterator = &new PrototypeIterator(); +$iterator->setReturnValue('next', 0); +</strong> +</pre> + Les méthodes <span class="new_code">next()</span> et <span class="new_code">isError()</span> peuvent maintenant renvoyer des ensembles de valeurs exactement comme si elles existaient dans la classe originale. + </p> + <p> + Un moyen encore plus ésotérique de modifier les bouchons est de changer le joker utiliser par défaut pour la correspondance des paramètres. +<pre> +<strong>Stub::generate('Connection'); +$iterator = &new StubConnection('wild'); +$iterator->setReturnValue('query', array('id' => 33), array('wild')); +</strong> +</pre> + L'unique raison valable pour effectuer cette opération, c'est quand vous souhaitez tester la chaîne "*" sans pour autant l'interpréter comme un "n'importe lequel". + </p> + + </div> +<div class="copyright"> + Copyright<br>Marcus Baker, Jason Sweat, Perrick Penet 2004 + </div> +</body> +</html> diff --git a/tests/test_tools/simpletest/docs/fr/unit_test_documentation.html b/tests/test_tools/simpletest/docs/fr/unit_test_documentation.html new file mode 100755 index 00000000..3dcfeca5 --- /dev/null +++ b/tests/test_tools/simpletest/docs/fr/unit_test_documentation.html @@ -0,0 +1,306 @@ +<html> +<head> +<META http-equiv="Content-Type" content="text/html; charset=UTF-8"> +<title>Documenation SimpleTest pour les tests de régression en PHP</title> +<link rel="stylesheet" type="text/css" href="docs.css" title="Styles"> +</head> +<body> +<div class="menu_back"> +<div class="menu"> +<h2> +<a href="index.html">SimpleTest</a> +</h2> +<ul> +<li> +<a href="overview.html">Overview</a> +</li> +<li> +<a href="unit_test_documentation.html">Unit tester</a> +</li> +<li> +<a href="group_test_documentation.html">Group tests</a> +</li> +<li> +<a href="server_stubs_documentation.html">Server stubs</a> +</li> +<li> +<a href="mock_objects_documentation.html">Mock objects</a> +</li> +<li> +<a href="partial_mocks_documentation.html">Partial mocks</a> +</li> +<li> +<a href="reporter_documentation.html">Reporting</a> +</li> +<li> +<a href="expectation_documentation.html">Expectations</a> +</li> +<li> +<a href="web_tester_documentation.html">Web tester</a> +</li> +<li> +<a href="form_testing_documentation.html">Testing forms</a> +</li> +<li> +<a href="authentication_documentation.html">Authentication</a> +</li> +<li> +<a href="browser_documentation.html">Scriptable browser</a> +</li> +</ul> +</div> +</div> +<h1>Documentation sur les tests unitaires en PHP</h1> +<div class="content"> + <p> +<a class="target" name="unitaire"> +<h2>Scénarios de tests unitaires</h2> +</a> +</p> + <p> + Le coeur du système est un framework de test de régression construit autour des scénarios de test.

Peuvent être ajoutées autant de méthodes de test que nécessaires. Par exemple... +<pre> +require_once('../classes/writer.php'); + +class FileTestCase extends UnitTestCase { + function FileTestCase() { + $this->UnitTestCase('File test'); + }<strong> + + function setUp() { + @unlink('../temp/test.txt'); + } + + function tearDown() { + @unlink('../temp/test.txt'); + } + + function testCreation() { + $writer = &new FileWriter('../temp/test.txt'); + $writer->write('Hello'); + $this->assertTrue(file_exists('../temp/test.txt'), 'File created'); + }</strong> +} +</pre> + Le constructeur est optionnel et souvent omis. Sans nom, le nom de la classe est utilisé comme nom pour le scénario de test. + </p> + <p> + Notre unique méthode de test pour le moment est <span class="new_code">testCreation()</span> où nous vérifions qu'un fichier a bien été créé par notre objet <span class="new_code">Writer</span>. Nous pourrions avoir mis le code <span class="new_code">unlink()</span> dans cette méthode, mais en la plaçant dans <span class="new_code">setUp()</span> et <span class="new_code">tearDown()</span> nous pouvons l'utiliser pour nos autres méthodes de test que nous ajouterons. + </p> + <p> + La méthode <span class="new_code">setUp()</span> est lancé juste avant chaque méthode de test. <span class="new_code">tearDown()</span> est lancé après chaque méthode de test. + </p> + <p> + Vous pouvez placer une initialisation de scénario de test dans le constructeur afin qu'elle soit lancée pour toutes les méthodes dans le scénario de test mais dans un tel cas vous vous exposeriez à des interférences. Cette façon de faire est légèrement moins rapide, mais elle est plus sûre. Notez que si vous arrivez avec des notions de JUnit, il ne s'agit pas du comportement auquel vous êtes habitués. Bizarrement JUnit re-instancie le scénario de test pour chaque méthode de test pour se prévenir d'une telle interférence. SimpleTest demande à l'utilisateur final d'utiliser <span class="new_code">setUp()</span>, mais fournit aux codeurs de bibliothèque d'autres crochets. + </p> + <p> + Pour rapporter les résultats de test, le passage par une classe d'affichage - notifiée par les différentes méthodes de type <span class="new_code">assert...()</span> - est utilisée. En voici la liste complète pour la classe <span class="new_code">UnitTestCase</span>, celle par défaut dans SimpleTest... + <table> +<tbody> + <tr> +<td><span class="new_code">assertTrue($x)</span></td><td>Echoue si $x est faux</td> +</tr> + <tr> +<td><span class="new_code">assertFalse($x)</span></td><td>Echoue si $x est vrai</td> +</tr> + <tr> +<td><span class="new_code">assertNull($x)</span></td><td>Echoue si $x est initialisé</td> +</tr> + <tr> +<td><span class="new_code">assertNotNull($x)</span></td><td>Echoue si $x n'est pas initialisé</td> +</tr> + <tr> +<td><span class="new_code">assertIsA($x, $t)</span></td><td>Echoue si $x n'est pas de la classe ou du type $t</td> +</tr> + <tr> +<td><span class="new_code">assertEqual($x, $y)</span></td><td>Echoue si $x == $y est faux</td> +</tr> + <tr> +<td><span class="new_code">assertNotEqual($x, $y)</span></td><td>Echoue si $x == $y est vrai</td> +</tr> + <tr> +<td><span class="new_code">assertIdentical($x, $y)</span></td><td>Echoue si $x === $y est faux</td> +</tr> + <tr> +<td><span class="new_code">assertNotIdentical($x, $y)</span></td><td>Echoue si $x === $y est vrai</td> +</tr> + <tr> +<td><span class="new_code">assertReference($x, $y)</span></td><td>Echoue sauf si $x et $y sont la même variable</td> +</tr> + <tr> +<td><span class="new_code">assertCopy($x, $y)</span></td><td>Echoue si $x et $y sont la même variable</td> +</tr> + <tr> +<td><span class="new_code">assertWantedPattern($p, $x)</span></td><td>Echoue sauf si l'expression rationnelle $p capture $x</td> +</tr> + <tr> +<td><span class="new_code">assertNoUnwantedPattern($p, $x)</span></td><td>Echoue si l'expression rationnelle $p capture $x</td> +</tr> + <tr> +<td><span class="new_code">assertNoErrors()</span></td><td>Echoue si une erreur PHP arrive</td> +</tr> + <tr> +<td><span class="new_code">assertError($x)</span></td><td>Echoue si aucune erreur ou message incorrect de PHP n'arrive</td> +</tr> + </tbody> +</table> + Toutes les méthodes d'assertion peuvent recevoir une description optionnelle : cette description sert pour étiqueter le résultat. + Sans elle, une message par défaut est envoyée à la place : il est généralement suffisant.

La partie "%s" est remplacée par le message d'erreur par défaut qui aurait été affiché si nous n'avions pas fourni le nôtre. Cela nous permet d'emboîter les messages de test. +<pre> +<strong>$a = 1; +$b = $a; +$this->assertReference($a, $b);</strong> +</pre> + Échouera étant donné que la variable <span class="new_code">$b</span> est une copie de <span class="new_code">$a</span>. +<pre> +<strong>$this->assertWantedPattern('/hello/i', 'Hello world');</strong> +</pre> + Là, ça passe puisque la recherche est insensible à la casse et que donc <span class="new_code">hello</span> est bien repérable dans <span class="new_code">Hello world</span>. +<pre> +<strong>trigger_error('Disaster'); +trigger_error('Catastrophe'); +$this->assertError(); +$this->assertError('Catastrophe'); +$this->assertNoErrors();</strong> +</pre> + Ici, il y a besoin d'une petite explication : toutes passent ! + </p> + <p> + Les erreurs PHP dans SimpleTest sont piégées et placées dans une queue. Ici la première vérification d'erreur attrape le message "Disaster" sans vérifier le texte et passe. Résultat : l'erreur est supprimée de la queue. La vérification suivante teste non seulement l'existence de l'erreur mais aussi le texte qui correspond : un autre succès. Désormais la queue est vide et le dernier test passe aussi. Si une autre erreur non vérifiée est encore dans la queue à la fin de notre méthode de test alors une exception sera rapportée dans le test. Notez que SimpleTest ne peut pas attraper les erreurs PHP à la compilation. + </p> + <p> + Les scénarios de test peuvent utiliser des méthodes bien pratiques pour déboguer le code ou pour étendre la suite... + <table> +<tbody> + <tr> +<td><span class="new_code">setUp()</span></td><td>Est lancée avant chaque méthode de test</td> +</tr> + <tr> +<td><span class="new_code">tearDown()</span></td><td>Est lancée après chaque méthode de test</td> +</tr> + <tr> +<td><span class="new_code">pass()</span></td><td>Envoie un succès</td> +</tr> + <tr> +<td><span class="new_code">fail()</span></td><td>Envoie un échec</td> +</tr> + <tr> +<td><span class="new_code">error()</span></td><td>Envoi un évènement exception</td> +</tr> + <tr> +<td><span class="new_code">sendMessage()</span></td><td>Envoie un message d'état aux systèmes d'affichage qui le supporte</td> +</tr> + <tr> +<td><span class="new_code">signal($type, $payload)</span></td><td>Envoie un message défini par l'utilisateur au rapporteur du test</td> +</tr> + <tr> +<td><span class="new_code">dump($var)</span></td><td>Effectue un <span class="new_code">print_r()</span> formaté pour du déboguage rapide et grossier</td> +</tr> + <tr> +<td><span class="new_code">swallowErrors()</span></td><td>Vide les erreurs de la queue</td> +</tr> + </tbody> +</table> + </p> + + <p> +<a class="target" name="extension_unitaire"> +<h2>Etendre les scénarios de test</h2> +</a> +</p> + <p> + Bien sûr des méthodes supplémentaires de test peuvent être ajoutées pour créer d'autres types de scénario de test afin d'étendre le framework... +<pre> +require_once('simpletest/unit_tester.php'); +<strong> +class FileTester extends UnitTestCase { + function FileTester($name = false) { + $this->UnitTestCase($name); + } + + function assertFileExists($filename, $message = '%s') { + $this->assertTrue( + file_exists($filename), + sprintf($message, 'File [$filename] existence check')); + }</strong> +} +</pre> + Ici la bibliothèque SimpleTest est localisée dans un répertoire local appelé <em>simpletest</em>.

Reste que PHP est avant tout un langage pour créer des fonctionnalités à l'intérieur de pages web. Comment pouvons tester la partie de devant -- celle de l'interface -- dans nos applications en PHP ? Etant donné qu'une page web n'est constituée que de texte, nous devrions pouvoir les examiner exactement comme n'importe quelle autre donnée de test. + </p> + <p> + Cela nous amène à une situation délicate. Si nous testons dans un niveau trop bas, vérifier des balises avec un motif ad hoc par exemple, nos tests seront trop fragiles. Le moindre changement dans la présentation pourrait casser un grand nombre de test. Si nos tests sont situés trop haut, en utilisant une version fantaisie du moteur de template pour donner un cas précis, alors nous perdons complètement la capacité à automatiser certaines classes de test. Par exemple, l'interaction entre des formulaires et la navigation devra être testé manuellement. Ces types de test sont extrêmement fastidieux et plutôt sensibles aux erreurs. + </p> + <p> + SimpleTest comprend une forme spéciale de scénario de test pour tester les actions d'une page web. <span class="new_code">WebTestCase</span> inclut des facilités pour la navigation, des vérifications sur le contenu et les cookies ainsi que la gestion des formulaires. Utiliser ces scénarios de test ressemble fortement à <span class="new_code">UnitTestCase</span>... +<pre> +<strong>class TestOfLastcraft extends WebTestCase { +}</strong> +</pre> + Ici nous sommes sur le point de tester le site de <a href="http://www/lastcraft.com/">Last Craft</a>.

C'est un moyen simple, mais efficace pour vérifier qu'une page web a bien été délivré par le serveur web. Cependant le contenu peut révéler être une erreur 404 et dans ce cas notre méthode <span class="new_code">get()</span> renverrait encore un succès. + </p> + <p> + En supposant que le serveur web pour le site Last Craft soit opérationnel (malheureusement ce n'est pas toujours le cas), nous devrions voir... +<pre class="shell"> +Web site tests +OK +Test cases run: 1/1, Failures: 0, Exceptions: 0 +</pre> + Nous avons vérifié qu'une page, de n'importe quel type, a bien été renvoyée.

Ce test passera, mais ce n'est pas la meilleure façon de procéder. Il n'existe aucune page sur <em>http://simpletest.sourceforge.net/</em>, à la place le serveur renverra une redirection vers <em>http://www.lastcraft.com/simple_test.php</em>. <span class="new_code">WebTestCase</span> suit automatiquement trois de ces redirections.

Le téléchargement via HTTP HEAD ne modifie pas le contexte du navigateur, il se limite au chargement des cookies. Cela peut être utilise lorsqu'une image ou une feuille de style initie un cookie pour bloquer un robot trop entreprenant. + </p> + <p> + Les commandes <span class="new_code">retry()</span>, <span class="new_code">back()</span> et <span class="new_code">forward()</span> fonctionnent exactement comme dans un navigateur. Elles utilisent l'historique pour relancer les pages. Une technique bien pratique pour vérifier les effets d'un bouton retour sur vos formulaires. + </p> + <p> + Les méthodes sur les fenêtres méritent une petite explication. Par défaut, une page avec des fenêtres est traitée comme toutes les autres. Le contenu sera vérifié à travers l'ensemble de la "frameset", par conséquent un lien fonctionnera, peu importe la fenêtre qui contient la balise ancre. Vous pouvez outrepassé ce comportement en exigeant le focus sur une unique fenêtre. Si vous réalisez cela, toutes les recherches et toutes les actions se limiteront à cette unique fenêtre, y compris les demandes d'authentification. Si un lien ou un bouton n'est pas dans la fenêtre en focus alors il ne peut pas être cliqué. + </p> + <p> + Tester la navigation sur des pages fixes ne vous alerte que quand vous avez cassé un script entier. Pour des pages fortement dynamiques, un forum de discussion par exemple, ça peut être crucial pour vérifier l'état de l'application. Pour la plupart des applications cependant, la logique vraiment délicate se situe dans la gestion des formulaires et des sessions.
