How about adding some more data in the AssertionError message if this doesn't match? Something like
assert len(w) == (1 if name in should_have_warning else 0), (name, [wg.message for wg in w])would help the next person who wants to debug why this assertion is failing.

Well, name is already available though the parametrization and will be printed as part of the test name. Pytest also prints out w, but unfortunately using the repr which doesn't look that great for warnings, so maybe adding that to the message wouldn't be a bad idea.

The merge up broke this. Sorry about that.
