Implementation looks reasonable to me, though obviously the test failures aren't ideal.
I'll unsubscribe for now but do @-me or re-request review when that'd be helpful!

Do you want to extract and pass on the cancel message?

Hm, might be a good idea.

This might cause problems in environments where pytest
is not installed? My habit is to do something like
OutcomeException = getattr(sys.modules.get("_pytest.outcomes"), "OutcomeException", ())
which doesn't require it to be installed and also avoids paying for the import if it wouldn't otherwise be used.

I'm not understanding. This is an import in the AnyIO pytest runner. Why would someone try to use that without pytest in the first place?

Ah, right, I just wasn't looking at a wide enough context 🤦

Thanks for the review! |
Changes
This fixes ctrl+c causing the anyio pytest plugin to hang if the test is currently awaiting something. This was caused by the test runner dropping exceptions on the floor.
