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

    def _wrapper(fun):
        @functools.wraps(fun)
        def _forward(self):
            for (key, value) in six.iteritems(kwargs):
                setattr(self.checker.config, key, value)
            if isinstance(self, CheckerTestCase):
                self.checker.open()
            fun(self)
        return _forward
    return _wrapper

What's a good function header?
