<p>The framework used is <a href="https://phpunit.de/">PHPUnit</a>; it can be installed with <a href="https://getcomposer.org/">Composer</a>, which is a dependency management tool.</p>
<p>Regarding Composer, you can either use:
<em> a system-wide version, e.g. installed through your distro's package manager
</em> a local version, downloadable <a href="https://getcomposer.org/download/">here</a></p>
<h4 id="sample-usage">Sample usage</h4>

<p>For ArchLinux:</p>
<pre><code class="bash">$ pacman -S xdebug

<h4 id="test-results-and-coverage">Test results and coverage</h4>
<p>By default, PHPUnit will run all suitable tests found under the <code>tests</code> directory.</p>
<p>Each test has 3 possible outcomes:
<em> <code>.</code> - success
</em> <code>F</code> - failure: the test was run but its results are invalid
* the code does not behave as expected
* dependencies to external elements: globals, session, cache...
* <code>E</code> - error: something went wrong and the tested code has crashed
* typos in the code, or in the test code
* dependencies to missing external elements</p>
<p>If Xdebug has been installed and activated, two coverage reports will be generated:
<em> a summary in the console
</em> a detailed HTML report with metrics for tested code
* to open it in a web browser: <code>firefox coverage/index.html &amp;</code></p>
<h3 id="executing-specific-tests">Executing specific tests</h3>
<p>Add a <a href="https://phpunit.de/manual/current/en/appendixes.annotations.html#appendixes.annotations.group"><code>@group</code></a> annotation in a test class or method comment:</p>
<pre><code class="php">/**
* Netscape bookmark import
* @group WIP
*/
class BookmarkImportTest extends PHPUnit_Framework_TestCase
{
[...]
}
</code></pre>
<p>To run all tests annotated with <code>@group WIP</code>:</p>
<pre><code class="bash">$ vendor/bin/phpunit --group WIP tests/
