Description

I'm wondering whether we should explicitly say in the docs that we prefer tm.assert_raises_regex over pytest.raises unless there is no error message to provide. The former is a lot more informative from a dev-perspective as to why certain code should fail.

Thoughts?

(If we can agree that we do prefer the former, I also move to convert some of the tests to use tm.assert_raises_regex instead of pytest.raises).
