4.8.0: pytest is failing

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

• "setup.py build"
• "setup.py install --root </install/prefix>"
• "pytest with PYTHONPATH pointing to sitearch and sitelib inside </install/prefix>

pytest is failing because it cannot find pytest_django_test which is in project root directory. Is it any special methdod to preload that modules during the test suite execution?

+ PYTHONPATH=/home/tkloczko/rpmbuild/BUILDROOT/python-pytest-django-4.5.1-2.fc35.x86_64/usr/lib64/python3.8/site-packages:/home/tkloczko/rpmbuild/BUILDROOT/python-pytest-django-4.5.1-2.fc35.x86_64/usr/lib/python3.8/site-packages
+ /usr/bin/pytest -ra tests

The above exception was the direct cause of the following exception:

Start with setup.py, the project-root pytest_django_test module, and the tests directory, then reproduce the documented build, install, and pytest commands with PYTHONPATH pointed at the installation prefix. Done means pytest can discover pytest_django_test and run the tests successfully in this non-root installed-package workflow.
