I'm testing an update of pytest to 7.2.0 and I've discovered that this package fails to build with it. The reason is a change related to `py` package.

`py` is an independent package developed by the same team as pytest and it has been bundled in pytest for quite some time. The `py` package itself is now in maintenance mode and pytest developers decided to bundle only a subset of its functionalities in pytest since version 7.2.0.

It seems that python-pytest-mock needs some parts of `py` that are no longer available in pytest (including deprecated `py.test` itself). There are two possible solutions:

1. Drop dependency on `py`. That requires some coordination with upstream but it's generally a good idea long-term.
2. Add python3-py to build dependencies. `py` package installed from python3-py will have a higher priority than py.py module bundled in pytest. This is a quick workaround but given the status of `py` project, it's only temporary.

If you want to, you can find the failed build in https://copr.fedorainfracloud.org/coprs/lbalhar/pytest/
