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

    def generator(func):
        @wraps(func)
        def deco(*args2, **kwargs2):
            app = TestApp(*args, **kwargs)
            func(app, *args2, **kwargs2)
            app.cleanup()
        return deco
    return generator

What's a good function header?
