    # "This method searches `module` for classes derived from TestCase"s
    #
    # What happens if loadTestsFromModule() is given something other
    # than a module?
    #
    # XXX Currently, it succeeds anyway. This flexibility
    # should either be documented or loadTestsFromModule() should
    # raise a TypeError
    #
    # XXX Certain people are using this behaviour. We'll add a test for it
