Okay, well, if it doesn't support it then it doesn't support it.

**But** I have to take this opportunity to say that his argument is _complete BS_: there's nothing special about `assert_nothing_raised` that makes it more susceptible to bad testing. In the example he gives, _that particular test_ would indeed pass by making `remove_column` a no-op. But elsewhere—assuming a sane test suite—there would undoubtedly be other tests that would fail because they assert other important things about the method (e.g. raising errors in particular circumstances).

You could make the exact same argument about literally any other assertion method, because one assertion in isolation is never enough to capture the behaviour of a piece of code.
