Could you please also add a test which checks for warning subclasses when the user passes more than one warning to pytest.warns? For example:
class Warn1(UserWarning): pass
class Warn2(RuntimeWarning): pass
with pytest.warns((UserWarning, RuntimeWarning)):
warnings.warn("w1", Warn1)
warnings.warn("w2", Warn2)
assert len(record) == 2

Not at all, I think this is a really nice recent addition in GitHub that maintainers can push into PR branches! |

lets use issubclass with the propper classinfo support here, no need for own loops, please check the docs
rather than class equality. This makes it more similar to pytest.raises.
