As of [35186] and [51568], there are two sets of methods used for setup/teardown in the test suite before and after a test class is run:
* `set_up_before_class()` / `tear_down_after_class()`
* `wpSetUpBeforeClass()` / `wpTearDownAfterClass()`. (Note the `wp` prefix, these are WordPress' own methods and are not the same as the native PHPUnit `setUpBeforeClass()` / `tearDownAfterClass()` methods.)
The main difference is that `wpSetUpBeforeClass()` receives the `$factory` argument for ease of use, and both `wpSetUpBeforeClass()` and `wpTearDownAfterClass()` don't need to call `self::commit_transaction()`.
Many tests use the `wpTearDownAfterClass()` method to clean up posts, users, roles, etc. created via `wpSetUpBeforeClass()`. However, due to [source:tags/6.0/tests/phpunit/includes/abstract-testcase.php?marks=88-95#L82 how the method was previously called], this cleanup happened after all data is **already deleted** from the database.
This could cause some confusion when refactoring tests. For example:
{{{
public static function wpTearDownAfterClass() {
$GLOBALS['_wp_additional_image_sizes'] = self::$_sizes;
}
public static function tear_down_after_class() {
wp_delete_attachment( self::$large_id, true );
parent::tear_down_after_class();
}
}}}
At a glance, it seems like these two methods can be combined:
{{{
public static function wpTearDownAfterClass() {
wp_delete_attachment( self::$large_id, true );
$GLOBALS['_wp_additional_image_sizes'] = self::$_sizes;
}
}}}
However, that would not work as expected: by the time `wp_delete_attachment()` runs, the attachment ID is no longer in the database, so it returns early, leaving some files in the `uploads` directory.
By calling `wpTearDownAfterClass()` in `WP_UnitTestCase_Base::tear_down_after_class()` before deleting all data, instead of after, we ensure that both of these methods have access to the same data and can be used interchangeably to perform cleanup as necessary.
Additionally, this commit moves the calls to parent methods in `WP_UnitTestCase_Base`:
* `parent::set_up_before_class()` to be the first thing called in `::set_up_before_class()`
* `parent::tear_down_after_class()` to be the last thing called in `::tear_down_after_class()`
This does not have any effect in practice, but brings consistency with how these methods are called in the test suite.
Follow-up to [35186], [35225], [35242], [38398], [39626], [49001], [51568].

The short version:
1. Create a clean MySQL database and user. DO NOT USE AN EXISTING DATABASE or you will lose data, guaranteed.
2. Copy wp-tests-config-sample.php to wp-tests-config.php, edit it and include your database name/user/password.
3. $ svn up
4. Run the tests from the "trunk" directory:
To execute a particular test:
$ phpunit tests/phpunit/tests/test_case.php
To execute all tests:
$ phpunit
Notes:
Test cases live in the 'tests' subdirectory. All files in that directory will be included by default. Extend the WP_UnitTestCase class to ensure your test is run.
phpunit will initialize and install a (more or less) complete running copy of WordPress each time it is run. This makes it possible to run functional interface and module tests against a fully working database and codebase, as opposed to pure unit tests with mock objects and stubs. Pure unit tests may be used also, of course.
Changes to the test database will be rolled back as tests are finished, to ensure a clean start next time the tests are run.
phpunit is intended to run at the command line, not via a web server.
