3.7.0: pytest is failing in `tests/test_pytest_mock.py::test_standalone_mock` unit

I’m trying to package your module as an rpm package. So I’m using the typical PEP517 based build, install and test cycle used on building packages from non-root account.

• python3 -sBm build -w --no-isolation
• because I’m calling build with --no-isolation I’m using during all processes only locally installed modules
• install .whl file in </install/prefix>
• run pytest with PYTHONPATH pointing to sitearch and sitelib inside </install/prefix>

Here is pytest output:

@kloczek I usually avoid releasing versions without user-facing changes, that’s why this has been sitting for a while.

But we have #296 open, which certainly warrants a new release once merged. 👍

[kloczek]

Looks clean now. Thank you 👍
