Add a custom TestCase class and an @add_fixtures decorator for tests.
Review Request #2574 — Created Sept. 3, 2011 and submitted
Add a custom TestCase class and an @add_fixtures decorator for tests. Tests that are on a Djblets TestCase subclass can augment or replace the fixtures they use through the @add_fixtures decorator. By default, this will add to the list of fixtures, but if replace=True is passed, it can replace the existing list. This allows test cases to be more specific about their fixture needs, which can speed up tests by not including the union of all required fixtures in TestCase.fixtures.
Used this with an accompanying Review Board change. Worked well.
