> Is there any advantage to having the test case in a separate MiscTestCase class, as opposed to the existing CgiTests class?

Other than "the first test [well, that I know of] for __all__ list was in separate class called MiscTestCase so each next one follows the same fashion" and "sometimes such test would fit into some existing TestCase class and sometimes not, so let's always put it into separate class for cohesion" - no, I don't see any.
