Browser</h1> +<div class="content"> + + <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

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

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>

+</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

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::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. + </p> + + <p> +<a class="target" name="unit"> +<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
