Inside the test suite should be one, and only one, call to  with the module name.

The unit tests for MediaWiki core are located in the  directory.

MediaWiki コア
Test suites are added to the registration of the  module in.

Tests are organised into a directory structure that matches the directory structure of the code being tested. For example: The unit test for  can be found at.
