Testing an extension

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 run-tests.php.

Tests for a particular module are stored in the tests/ subdirectory of the module's folder, and have a .phpt extension. For details of the PHPT format, see » http://qa.php.net/.
