@hjwp do you want me to extract issue 2 into a separate commit?

can't reproduce issue, but instead got a new issue when running pytest directly

ImportError: No module named 'djangoproject'

pytest-django could not find a Django project (no manage.py file could be found). You must explicitly add your Django project to the Python path to have it picked up.
