+<h1>PHP Scriptable Web Browser</h1>

+
+ <p>
+ SimpleTest's web browser component can be used not just
+ outside of the <span class="new_code">WebTestCase</span> class, but also
+ independently of the SimpleTest framework itself.
+ </p>
+
+ <p>
+<a class="target" name="scripting">
+<h2>The Scriptable Browser</h2>
+</a>
+</p>
+ <p>
+ You can use the web browser in PHP scripts to confirm
+ services are up and running, or to extract information
+ from them at a regular basis.
+ For example, here is a small script to extract the current number of
+ open PHP 5 bugs from the <a href="http://www.php.net/">PHP web site</a>...
+<pre>
+<strong><?php
+ require_once('simpletest/browser.php');
+
+ $browser = &new SimpleBrowser();
+ $browser->get('http://php.net/');
+ $browser->clickLink('reporting bugs');
+ $browser->clickLink('statistics');
+ $page = $browser->clickLink('PHP 5 bugs only');
+ preg_match('/status=Open.*?by=Any.*?(\d+)<\/a>/', $page, $matches);
+ print $matches[1];
+?></strong>
+</pre>
+ There are simpler methods to do this particular example in PHP
+ of course.
+ For example you can just use the PHP <span class="new_code">file()</span>
+ command against what here is a pretty fixed page.
+ However, using the web browser for scripts allows authentication,
+ correct handling of cookies, automatic loading of frames, redirects,
+ form submission and the ability to examine the page headers.
+ Such methods are fragile against a site that is constantly
+ evolving and you would want a more direct way of accessing
+ data in a permanent set up, but for simple tasks this can provide
+ a very rapid solution.
+ </p>
+ <p>
+ All of the navigation methods used in the
+ <a href="web_tester_documentation.html">WebTestCase</a>
+ are present in the <span class="new_code">SimpleBrowser</span> class, but
+ the assertions are replaced with simpler accessors.
+ Here is a full list of the page navigation methods...
+ <table>
+<tbody>
+ <tr>
+<td><span class="new_code">addHeader($header)</span></td><td>Adds a header to every fetch</td>
+</tr>
+ <tr>
+<td><span class="new_code">useProxy($proxy, $username, $password)</span></td><td>Use this proxy from now on</td>
+</tr>
+ <tr>
+<td><span class="new_code">head($url, $parameters)</span></td><td>Perform a HEAD request</td>
+</tr>
+ <tr>
+<td><span class="new_code">get($url, $parameters)</span></td><td>Fetch a page with GET</td>
+</tr>
+ <tr>
+<td><span class="new_code">post($url, $parameters)</span></td><td>Fetch a page with POST</td>
+</tr>
+ <tr>
+<td><span class="new_code">clickLink($label)</span></td><td>Follows a link by label</td>
+</tr>
+ <tr>
+<td><span class="new_code">isLink($label)</span></td><td>See if a link is present by label</td>
+</tr>
+ <tr>
+<td><span class="new_code">clickLinkById($id)</span></td><td>Follows a link by attribute</td>
+</tr>
+ <tr>
+<td><span class="new_code">isLinkById($id)</span></td><td>See if a link is present by attribut</td>
+</tr>
+ <tr>
+<td><span class="new_code">getUrl()</span></td><td>Current URL of page or frame</td>
+</tr>
+ <tr>
+<td><span class="new_code">getTitle()</span></td><td>Page title</td>
+</tr>
+ <tr>
+<td><span class="new_code">getContent()</span></td><td>Raw page or frame</td>
+</tr>
+ <tr>
+<td><span class="new_code">getContentAsText()</span></td><td>HTML removed except for alt text</td>
+</tr>
+ <tr>
+<td><span class="new_code">retry()</span></td><td>Repeat the last request</td>
+</tr>
+ <tr>
+<td><span class="new_code">back()</span></td><td>Use the browser back button</td>
+</tr>
+ <tr>
+<td><span class="new_code">forward()</span></td><td>Use the browser forward button</td>
+</tr>
+ <tr>
+<td><span class="new_code">authenticate($username, $password)</span></td><td>Retry page or frame after a 401 response</td>
+</tr>
+ <tr>
+<td><span class="new_code">restart($date)</span></td><td>Restarts the browser for a new session</td>
+</tr>
+ <tr>
+<td><span class="new_code">ageCookies($interval)</span></td><td>Ages the cookies by the specified time</td>
+</tr>
+ <tr>
+<td><span class="new_code">setCookie($name, $value)</span></td><td>Sets an additional cookie</td>
+</tr>
+ <tr>
+<td><span class="new_code">getCookieValue($host, $path, $name)</span></td><td>Reads the most specific cookie</td>
+</tr>
+ <tr>
+<td><span class="new_code">getCurrentCookieValue($name)</span></td><td>Reads cookie for the current context</td>
+</tr>
+ </tbody>
+</table>
+ The methods <span class="new_code">SimpleBrowser::useProxy()</span> and
+ <span class="new_code">SimpleBrowser::addHeader()</span> are special.
+ Once called they continue to apply to all subsequent fetches.
+ </p>
+ <p>
+ Navigating forms is similar to the
+ <a href="form_testing_documentation.html">WebTestCase form navigation</a>...
+ <table>
+<tbody>
+ <tr>
+<td><span class="new_code">setField($name, $value)</span></td><td>Sets all form fields with that name</td>
+</tr>
+ <tr>
+<td><span class="new_code">setFieldById($id, $value)</span></td><td>Sets all form fields with that id</td>
+</tr>
+ <tr>
+<td><span class="new_code">getField($name)</span></td><td>Accessor for a form element value</td>
+</tr>
+ <tr>
+<td><span class="new_code">getFieldById($id)</span></td><td>Accessor for a form element value</td>
+</tr>
+ <tr>
+<td><span class="new_code">clickSubmit($label)</span></td><td>Submits form by button label</td>
+</tr>
+ <tr>
+<td><span class="new_code">clickSubmitByName($name)</span></td><td>Submits form by button attribute</td>
+</tr>
+ <tr>
+<td><span class="new_code">clickSubmitById($id)</span></td><td>Submits form by button attribute</td>
+</tr>
+ <tr>
+<td><span class="new_code">clickImage($label, $x, $y)</span></td><td>Clicks the image by alt text</td>
+</tr>
+ <tr>
+<td><span class="new_code">clickImageByName($name, $x, $y)</span></td><td>Clicks the image by attribute</td>
+</tr>
+ <tr>
+<td><span class="new_code">clickImageById($id, $x, $y)</span></td><td>Clicks the image by attribute</td>
+</tr>
+ <tr>
+<td><span class="new_code">submitFormById($id)</span></td><td>Submits by the form tag attribute</td>
+</tr>
+ </tbody>
+</table>
+ At the moment there aren't any methods to list available forms
+ and fields.
+ This will probably be added to later versions of SimpleTest.
+ </p>
+ <p>
+ Within a page, individual frames can be selected.
+ If no selection is made then all the frames are merged together
+ in one large conceptual page.
+ The content of the current page will be a concatenation of all of the
+ frames in the order that they were specified in the "frameset"
+ tags.
+ <table>
+<tbody>
+ <tr>
+<td><span class="new_code">getFrames()</span></td><td>A dump of the current frame structure</td>
+</tr>
+ <tr>
+<td><span class="new_code">getFrameFocus()</span></td><td>Current frame label or index</td>
+</tr>
+ <tr>
+<td><span class="new_code">setFrameFocusByIndex($choice)</span></td><td>Select a frame numbered from 1</td>
+</tr>
+ <tr>
+<td><span class="new_code">setFrameFocus($name)</span></td><td>Select frame by label</td>
+</tr>
+ <tr>
+<td><span class="new_code">clearFrameFocus()</span></td><td>Treat all the frames as a single page</td>
+</tr>
+ </tbody>
+</table>
+ When focused on a single frame, the content will come from
+ that frame only.
+ This includes links to click and forms to submit.
+ </p>
+
+ <p>
+<a class="target" name="debug">
+<h2>What went wrong?</h2>
+</a>
+</p>
+ <p>
+ All of this functionality is great when we actually manage to fetch pages,
+ but that doesn't always happen.
+ To help figure out what went wrong, the browser has some methods to
+ aid in debugging...
+ <table>
+<tbody>
+ <tr>
+<td><span class="new_code">setConnectionTimeout($timeout)</span></td><td>Close the socket on overrun</td>
+</tr>
+ <tr>
+<td><span class="new_code">getRequest()</span></td><td>Raw request header of page or frame</td>
+</tr>
+ <tr>
+<td><span class="new_code">getHeaders()</span></td><td>Raw response header of page or frame</td>
+</tr>
+ <tr>
+<td><span class="new_code">getTransportError()</span></td><td>Any socket level errors in the last fetch</td>
+</tr>
+ <tr>
+<td><span class="new_code">getResponseCode()</span></td><td>HTTP response of page or frame</td>
+</tr>
+ <tr>
+<td><span class="new_code">getMimeType()</span></td><td>Mime type of page or frame</td>
+</tr>
+ <tr>
+<td><span class="new_code">getAuthentication()</span></td><td>Authentication type in 401 challenge header</td>
+</tr>
+ <tr>
+<td><span class="new_code">getRealm()</span></td><td>Authentication realm in 401 challenge header</td>
+</tr>
+ <tr>
+<td><span class="new_code">setMaximumRedirects($max)</span></td><td>Number of redirects before page is loaded anyway</td>
+</tr>
+ <tr>
+<td><span class="new_code">setMaximumNestedFrames($max)</span></td><td>Protection against recursive framesets</td>
+</tr>
+ <tr>
+<td><span class="new_code">ignoreFrames()</span></td><td>Disables frames support</td>
+</tr>
+ <tr>
+<td><span class="new_code">useFrames()</span></td><td>Enables frames support</td>
+</tr>
+ </tbody>
+</table>
+ The methods <span class="new_code">SimpleBrowser::setConnectionTimeout()</span>
+ <span class="new_code">SimpleBrowser::setMaximumRedirects()</span>,
+ <span class="new_code">SimpleBrowser::setMaximumNestedFrames()</span>,
+ <span class="new_code">SimpleBrowser::ignoreFrames()</span> and
+ <span class="new_code">SimpleBrowser::useFrames()</span> continue to apply
+ to every subsequent request.
+ The other methods are frames aware.
+ This means that if you have an individual frame that is not
+ loading, navigate to it using <span class="new_code">SimpleBrowser::setFrameFocus()</span>
+ and you can then use <span class="new_code">SimpleBrowser::getRequest()</span>, etc to
+ see what happened.

+<h2>Complex unit tests with multiple browsers</h2>
+</a>
+</p>
+ <p>
+ Anything that could be done in a
+ <a href="web_tester_documentation.html">WebTestCase</a> can
+ now be done in a <a href="unit_tester_documentation.html">UnitTestCase</a>.
+ This means that we can freely mix domain object testing with the
+ web interface...
+<pre>
+<strong>
+class TestOfRegistration extends UnitTestCase {
+ function testNewUserAddedToAuthenticator() {</strong>
+ $browser = &new SimpleBrowser();
+ $browser->get('http://my-site.com/register.php');
+ $browser->setField('email', 'me@here');
+ $browser->setField('password', 'Secret');
+ $browser->clickSubmit('Register');
+ <strong>
+ $authenticator = &new Authenticator();
+ $member = &$authenticator->findByEmail('me@here');
+ $this->assertEqual($member->getPassword(), 'Secret');
+ }
+}</strong>
+</pre>
+ While this may be a useful temporary expediency, I am not a fan
+ of this type of testing.
+ The testing has cut across application layers, make it twice as
+ likely it will need refactoring when the code changes.
+ </p>
+ <p>
+ A more useful case of where using the browser directly can be helpful
+ is where the <span class="new_code">WebTestCase</span> cannot cope.
+ An example is where two browsers are needed at the same time.
+ </p>
+ <p>
+ For example, say we want to disallow multiple simultaneous
+ usage of a site with the same username.
+ This test case will do the job...
+<pre>
+class TestOfSecurity extends UnitTestCase {
+ function testNoMultipleLoginsFromSameUser() {<strong>
+ $first = &new SimpleBrowser();
+ $first->get('http://my-site.com/login.php');
+ $first->setField('name', 'Me');
+ $first->setField('password', 'Secret');
+ $first->clickSubmit('Enter');
+ $this->assertEqual($first->getTitle(), 'Welcome');
+
+ $second = &new SimpleBrowser();
+ $second->get('http://my-site.com/login.php');
+ $second->setField('name', 'Me');
+ $second->setField('password', 'Secret');
+ $second->clickSubmit('Enter');
+ $this->assertEqual($second->getTitle(), 'Access Denied');</strong>
+ }
+}
+</pre>
+ You can also use the <span class="new_code">SimpleBrowser</span> class
+ directly when you want to write test cases using a different
+ test tool than SimpleTest.
