Yes. I like the general mechanism of Approval Tests, although I very slightly prefer "generate golden master" and "run the test" as separate activities with different ways to launch. (Just an expression of my desire for control, I guess.) I imagine the difference is so small that I would get quite comfortable with both ways of thinking about it. (If a file named X happens to be there, then we know the expected result, and if not, then we don't and the test can't pass.)
