<h2 class="title">Testing an extension</h2>
<p class="simpara">
One of the accepted requirements of good programming is testing. PHP provides
a test harness for unit regression tests, in the form of a script called
<strong class="command">run-tests.php</strong>.
</p>
<p class="simpara">
Tests for a particular module are stored in the <var class="filename">tests/</var>
subdirectory of the module's folder, and have a <var class="filename">.phpt</var>
extension. For details of the PHPT format, see
<a href="http://qa.php.net/" class="link external">» http://qa.php.net/</a>.
