 In [changeset:"35186"]:
 {{{
 #!CommitTicketReference repository="" revision="35186"
 Unit Tests: implement `setUpBeforeClass()` and `tearDownAfterClass()` on
 `WP_UnitTestCase`. Use late static binding (plus a gross fallback for PHP
 5.2) to check if `wpSetUpBeforeClass()` or `wpTearDownAfterClass()` exist
 on the called class, and then call it and pass a static
 `WP_UnitTest_Factory` instance via Dependency Injection, if it exists.

 This makes it way easier to add fixtures, and tear them down, without
 needing to instantiate `WP_UnitTest_Factory` in every class - removes the
 need to call `commit_transaction()` in each individual class.

 See #30017, #33968.
