+<h1>Form testing documentation</h1>
+<div class="content">
+ <p>
+<a class="target" name="submit">
+<h2>Submitting a simple form</h2>
+</a>
+</p>
+ <p>
+ When a page is fetched by the <span class="new_code">WebTestCase</span>
+ using <span class="new_code">get()</span> or
+ <span class="new_code">post()</span> the page content is
+ automatically parsed.
+ This results in any form controls that are inside <form> tags
+ being available from within the test case.
+ For example, if we have this snippet of HTML...
+<pre>
+<form>
+ <input type="text" name="a" value="A default" />
+ <input type="submit" value="Go" />
+</form>
+</pre>
+ Which looks like this...
+ </p>
+ <p>
+ <form class="demo">
+ <input type="text" name="a" value="A default">
+ <input type="submit" value="Go">
+ </form>
+ </p>
+ <p>
+ We can navigate to this code, via the
+ <a href="http://www.lastcraft.com/form_testing_documentation.php">LastCraft</a>
+ site, with the following test...
+<pre>
+class SimpleFormTests extends WebTestCase {
+ <strong>
+ function testDefaultValue() {
+ $this->get('http://www.lastcraft.com/form_testing_documentation.php');
+ $this->assertField('a', 'A default');
+ }</strong>
+}
+</pre>
+ Immediately after loading the page all of the HTML controls are set at
+ their default values just as they would appear in the web browser.
+ The assertion tests that a HTML widget exists in the page with the
+ name "a" and that it is currently set to the value
+ "A default"
+ </p>
+ <p>
+ We could submit the form straight away, but first we'll change
+ the value of the text field and only then submit it...
+<pre>
+class SimpleFormTests extends WebTestCase {
+
+ function testDefaultValue() {
+ $this->get('http://www.my-site.com/');
+ $this->assertField('a', 'A default');<strong>
+ $this->setField('a', 'New value');
+ $this->clickSubmit('Go');</strong>
+ }
+}
+</pre>
+ Because we didn't specify a method attribute on the form tag, and
+ didn't specify an action either, the test case will follow
+ the usual browser behaviour of submitting the form data as a <em>GET</em>
+ request back to the same location.
+ SimpleTest tries to emulate typical browser behaviour as much as possible,
+ rather than attempting to catch missing attributes on tags.
+ This is because the target of the testing framework is the PHP application
+ logic, not syntax or other errors in the HTML code.
+ For HTML errors, other tools such as
+ <a href="http://www.w3.org/People/Raggett/tidy/">HTMLTidy</a> should be used.
+ </p>
+ <p>
+ If a field is not present in any form, or if an option is unavailable,
+ then <span class="new_code">WebTestCase::setField()</span> will return
+ <span class="new_code">false</span>.
+ For example, suppose we wish to verify that a "Superuser"
+ option is not present in this form...
+<pre>
+<strong>Select type of user to add:</strong>
+<select name="type">
+ <option>Subscriber</option>
+ <option>Author</option>
+ <option>Administrator</option>
+</select>
+</pre>
+ Which looks like...
+ </p>
+ <p>
+ <form class="demo">
+ <strong>Select type of user to add:</strong>
+ <select name="type">
+ <option>Subscriber</option>
+ <option>Author</option>
+ <option>Administrator</option>
+ </select>
+ </form>
+ </p>
+ <p>
+ The following test will confirm it...
+<pre>
+class SimpleFormTests extends WebTestCase {
+ ...
+ function testNoSuperuserChoiceAvailable() {<strong>
+ $this->get('http://www.lastcraft.com/form_testing_documentation.php');
+ $this->assertFalse($this->setField('type', 'Superuser'));</strong>
+ }
+}
+</pre>
+ The selection will not be changed on a failure to set
+ a widget value.
+ </p>
+ <p>
+ Here is the full list of widgets currently supported...
+ <ul>
+ <li>Text fields, including hidden and password fields.</li>
+ <li>Submit buttons including the button tag, although not yet reset buttons</li>
+ <li>Text area. This includes text wrapping behaviour.</li>
+ <li>Checkboxes, including multiple checkboxes in the same form.</li>
+ <li>Drop down selections, including multiple selects.</li>
+ <li>Radio buttons.</li>
+ <li>Images.</li>
+ </ul>
+ </p>
+ <p>
+ Although most standard HTML widgets are catered for by <em>SimpleTest</em>'s
+ built in parser, it is unlikely that JavaScript will be implemented
+ anytime soon.
+ </p>
+
+ <p>
+<a class="target" name="multiple">
+<h2>Fields with multiple values</h2>
+</a>
+</p>
+ <p>
+ SimpleTest can cope with two types of multivalue controls: Multiple
+ selection drop downs, and multiple checkboxes with the same name
+ within a form.
+ The multivalue nature of these means that setting and testing
+ are slightly different.
+ Using checkboxes as an example...
+<pre>
+<form class="demo">
+ <strong>Create privileges allowed:</strong>
+ <input type="checkbox" name="crud" value="c" checked><br>
+ <strong>Retrieve privileges allowed:</strong>
+ <input type="checkbox" name="crud" value="r" checked><br>
+ <strong>Update privileges allowed:</strong>
+ <input type="checkbox" name="crud" value="u" checked><br>
+ <strong>Destroy privileges allowed:</strong>
+ <input type="checkbox" name="crud" value="d" checked><br>
+ <input type="submit" value="Enable Privileges">
+</form>
+</pre>
+ Which renders as...
+ </p>
+ <p>
+ <form class="demo">
+ <strong>Create privileges allowed:</strong>
+ <input type="checkbox" name="crud" value="c" checked>
+<br>
+ <strong>Retrieve privileges allowed:</strong>
+ <input type="checkbox" name="crud" value="r" checked>
+<br>
+ <strong>Update privileges allowed:</strong>
+ <input type="checkbox" name="crud" value="u" checked>
+<br>
+ <strong>Destroy privileges allowed:</strong>
+ <input type="checkbox" name="crud" value="d" checked>
+<br>
+ <input type="submit" value="Enable Privileges">
+ </form>
+ </p>
+ <p>
+ If we wish to disable all but the retrieval privileges and
+ submit this information we can do it like this...
+<pre>
+class SimpleFormTests extends WebTestCase {
+ ...<strong>
+ function testDisableNastyPrivileges() {
+ $this->get('http://www.lastcraft.com/form_testing_documentation.php');
+ $this->assertField('crud', array('c', 'r', 'u', 'd'));
+ $this->setField('crud', array('r'));
+ $this->clickSubmit('Enable Privileges');
+ }</strong>
+}
+</pre>
+ Instead of setting the field to a single value, we give it a list
+ of values.
+ We do the same when testing expected values.
+ We can then write other test code to confirm the effect of this, perhaps
+ by logging in as that user and attempting an update.
+ </p>
+ <p>
+ <a class="target" name="raw">
+<h2>Raw posting</h2>
+</a>
+ </p>
+ <p>
+ If you want to test a form handler, but have not yet written
+ or do not have access to the form itself, you can create a
+ form submission by hand.
+<pre>
+class SimpleFormTests extends WebTestCase {
+ ...<strong>
+ function testAttemptedHack() {
+ $this->post(
+ 'http://www.my-site.com/add_user.php',
+ array('type' => 'superuser'));
+ $this->assertNoUnwantedPattern('/user created/i');
+ }</strong>
+}
+</pre>
+ By adding data to the <span class="new_code">WebTestCase::post()</span>
+ method, we are attempting to fetch the page as a form submission.
