Bug 2059974

In this copr repo, I have updated pytest to 7.0.1:

https://copr.fedorainfracloud.org/coprs/churchyard/pytest-7/

Based on this PR:

https://src.fedoraproject.org/rpms/pytest/pull-request/25

I'd like to update pytest to 7 in Fedora 37, but python-trio 0.19.0-2 fails to build.

This looks like pytest.warns(None) and that does not work, see https://github.com/pytest-dev/pytest/issues/9002



There are several packages affected by this update, so I'd very much appreciate it if you could fix this failure. Please, check if your upstream hasn't already fixed it and backport the fix if possible. Report this failure to your upstream otherwise. If you need specific help, let me know.

Thanks!
