Here's a good function header given the following:
I wrote the below code

    if inspect.isclass(caller):
        old_setup = getattr(caller, 'setUp', None)
        def setUp(self, *args, **kwargs):
            if (os.environ.get('SSH_DAEMON_RUNNING', 'False').lower() == 'false'):
                self.skipTest('SSH    tests    are    disabled')
            if (old_setup is not None):
                old_setup(self, *args, **kwargs)
        caller.setUp = setUp
        return caller
    @functools.wraps(caller)
    def wrap(cls):
        if (os.environ.get('SSH_DAEMON_RUNNING', 'False').lower() == 'false'):
            cls.skipTest('SSH    tests    are    disabled')
        return caller(cls)
    return wrap

What's a good function header?
