Subject: Fix test_enum_class with Python 3.10-beta4

Feature or Bugfix

• Bugfix

Detail

The fix was tested during rpm package build in Fedora, which then succeeded.
Because the changes were only postponed, I propose to keep the if/else clause, but removing it entirely is also an option.

See this relevant discussion in pytest, where we decided to remove it entirely: pytest-dev/pytest#8895

Thanks! I did not notice the change.
+1 for removing it entirely too.

[befeleme]

I've changed the code accordingly and tested that it builds in Fedora successfully.

Hmm... It seems CI has been broken because 3.10-dev @ deadsnakes is still 3.10.0b2+. I don't know why b4 is not still packaged. Anyway, we need to wait for merging this until upgrading.

Now 3.10-dev @ deadsnakes is updated. So I just merged this. Thank you for your contribution!
