404<p>By default, PHPUnit will run all suitable tests found under the <code>tests</code> directory.</p>
405<p>Each test has 3 possible outcomes:
406<em> <code>.</code> - success
407</em> <code>F</code> - failure: the test was run but its results are invalid
408 * the code does not behave as expected
409 * dependencies to external elements: globals, session, cache...
410* <code>E</code> - error: something went wrong and the tested code has crashed
411 * typos in the code, or in the test code
412 * dependencies to missing external elements</p>
413<p>If Xdebug has been installed and activated, two coverage reports will be generated:
414<em> a summary in the console
415</em> a detailed HTML report with metrics for tested code
416 * to open it in a web browser: <code>firefox coverage/index.html &amp;</code></p>
