Can you please try the 0.18.0 test dependencies to run tests? https://github.com/python-trio/trio/blob/v0.18.0/test-requirements.txt. For example, we don't support pytest 6.2.1.

[pquentin]

Closing, please reopen if it still fails with the correct dependencies.

[kloczek]

Just tested that and it looks now OK.
