4.8.0: pytest is failing

[kloczek]

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

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

I've been trying to run pytest with --pyargs pytest_django_test but it did not helped. How pytest-django shoud be tested using pytest?

gentle ping 😃

I just had a similar problem when trying to test pytest-django on Solaris, and the problem was that pytest_django_test isn't being delivered, meaning that if you are running the test suite on installed packages or in proto area (which was our issue), it won't work. Adding the source directory to PYTHONPATH fixed the issue.

Just tested 4.8.0 with django 5.03, python 3.9.18 and pytest 8.1.1 and now pytest fails other way

Here is pytest output:
