Running pytest programatically, like pytest - how should I be doing this?

[mrchrisadams]

Hi there,

I'm trying to work out how to run pytest-watch programatically, a bit like how this example of pytest is run here, so I can run it from within python,

https://github.com/barseghyanartur/django-elasticsearch-dsl-drf/blob/master/runtests.py

The thing is, I don't think I understand how paths are treated by pytest-watch. I'm able to run the command above successfully, but when I try to use pytest-watch in a similar fashion, I'm getting an error along the lines of

ImportError: No module named 'settings'

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.

In the code below, I am explicitly adding the django project to the python path with sys.path.insert(0, "examples/simple").

#!/usr/bin/env python
import os
import sys

import pytest

def main():
    from pytest_watch.command import main as pt_main

    os.environ.setdefault("DJANGO_SETTINGS_MODULE", "settings.testing")
    sys.path.insert(0, "src")
    sys.path.insert(0, "examples/simple")

    pt_main()
    # return pytest.main('-x')

if __name__ == '__main__':
    sys.exit(main())

I've only really used pytest-watch as a consumer of it, but I'm up for having a go at making a PR if some extra code is needed to support it.

I could of course just be using it wrong - if this is the case, any chance of a pointer to see what I ought to be doing to get paths recognised properly?
