Manual:PHP unit testing/en

Introduction
We do unit testing of MediaWiki's PHP code base using the PHPUnit framework. View our test coverage.

Core MediaWiki PHP unit tests are in the  directory. The directory structure roughly matches that of the code being tested. For example: you can find the unit tests for file  in.

Extensions often have tests in a  subdirectory.
