This should be what works everywhere tho.  Instead of hoping that
"py.test" will be the right python version we tell python3 to use the
pytest module it has.  So if you have system python3-pytest, that works,
if you (python3) pip install pytest locally, that works and if you
virtualenv + python3 + pip install pytest, that works.
