You can follow these instructions to test locally in mock if your package builds with Python 3.11: https://copr.fedorainfracloud.org/coprs/g/python/python3.11/ Let us know here if you have any questions. Python 3.11 is planned to be included in Fedora 37. To make that update smoother, we're building Fedora packages with all pre-releases of Python 3.11. A build failure prevents us from testing all dependent packages (transitive [Build]Requires), so if this package is required a lot, it's important for us to get it fixed soon. We'd appreciate help from the people who know this package best, but if you don't want to work on this now, let us know so we can try to work around it on our side.
Fixed in https://github.com/google/yapf/commit/8ec4ed6fdd68c2a70809b99c788b7061876a746b, released in v0.32.0.
This bug appears to have been reported against 'rawhide' during the Fedora 36 development cycle. Changing version to 36.
Removal of unittest aliases was reverted in Python 3.11 and will be part of Python 3.12, so the above failure is not present anymore, thus I am closing this bugzilla. However, this will be needed next year though so I encourage you to communicate with the upstream about it.
