gh-100690: Mock objects which are not unsafe
will now raise an AttributeError when accessing an attribute that matches the
name of an assertion but without the prefix assert_, e.g. accessing called_once
instead of assert_called_once. This is in addition to this already happening
for accessing attributes with prefixes assert, assret, asert, aseert, and
assrt.

For all our attempts to build python-qstylizer with Python 3.12, see:

Testing and mass rebuild of packages is happening in copr. You can follow these instructions to test locally in mock if your package builds with Python 3.12:
https://copr.fedorainfracloud.org/coprs/g/python/python3.12/

Let us know here if you have any questions.

Python 3.12 is planned to be included in Fedora 39. To make that update smoother, we're building Fedora packages with all pre-releases of Python 3.12.
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.
