notification tests: delete notifications before (not after) tests Don't clean notifications (and changeset comments) *after* the test, but *before* the test. Other unit tests don't care if they leave notifications in the database, and neither should these. Rather, they should ensure their *own* preconditions before testing. Admittedly, currently only one test leaves a notification in the database, but more could come along at any time (and why worry?): TestPullrequestsController.test_create_with_existing_reviewer
