Comment (by matthias.thiel):

 I am not sure the current implementation resolves the issue properly.
 Adding a filter in the static `setUpBeforeClass` method will still exist
 in test cases that are run later. I advise putting the hook into the
 `setUp` method like the `wp_die_ajax_handler` hook.

 I think this would also be more in line with the `WP_UnitTestCase` class
 as it backs up all hooks in the `setUp` method.
