For example  in content_validity check , I thought of implementing it like this, to run on both init and test responses, if not test.init_signals.find(possible_slugs):
        resp = test.init_res
        return content_check(resp) 
but this will always run only the init_signals check if there was no json/xml content as the check returns a slug only if any of these are present..
