That's the way to do it.

In general, it's best to avoid dealing directly with internal state on
an object that you're specifying and only manipulate its state through
public methods and/or mocks/stubs on collaborators. So in this case,
I'd just stub Comment.find, as mentioned above.

Nope. For the reasons stated above. This is too invasive.
