Simpler way to run pytest from manage.py script?

[paduszyk]

Docs suggest to define custom test runner to invoke pytest (thus, related pytest-django functionality) via the manage.py script.

I used the following snippet and everything works as expected:

# manage.py
import sys
from pathlib import Path

import environ

from django.core.management import execute_from_command_line


def main():
    if (dotenv_path := Path(__file__).parent / ".env").exists():
        environ.Env.read_env(dotenv_path)

    if sys.argv[1:2] == ["test"]:
        import pytest

        sys.exit(pytest.main(sys.argv[2:]))

    execute_from_command_line(sys.argv)


if __name__ == "__main__":
    main()

What are the advantages of the solution presented in the docs compared to the one above? Thanks in advance for any feedback.

The only advantage is that it's a bit more integrated with Django, e.g. the command line parsing. But if what you did works for you, I don't see much problem with it!

if anyone ever tried to debug this / add any arguments, this will get chaotic quick.

Personally, I use the pytest args --last-failed / -x / -s / -vv / --pdb daily. Not being able to specify them at will, because you dont want them on all the time, makes this solution very poor.
And --pdbcls=IPython.terminal.debugger:TerminalPdb is on by default inside pyproject.toml. Example

But like @bluetech, said, if this solution works for you, 👍

@bluetech Why isn't PytestTestRunner included in the library to lower the entry level? It would be much faster to add TEST_RUNNER = 'pytest_django.runner.PytestTestRunner' than it is to copy it somewhere into your own repo and maintain it -- if you need more customizing just override it with your own while inheriting from one provided by pytest_django -- no?
