The preferred way to invoke pytest is via the pytest command. Even the app pytest-django doesn't provide a management command to invoke pytest.
But I prefer to invoke my django project through a single place, which is the manage.py script at the project root. So I just add it to the script:-
#!/usr/bin/env python
"""Django's command-line utility for administrative tasks."""
import os
import sys
import pathlib
import subprocess
def main():
BASE_DIR = pathlib.Path(__file__).parent.absolute()
sys.path[0] = str(BASE_DIR / "src")
"""Run administrative tasks."""
os.environ.setdefault("DJANGO_SETTINGS_MODULE", "medan.settings")
try:
from django.core.management import execute_from_command_line
except ImportError as exc:
raise ImportError(
"Couldn't import Django. Are you sure it's installed and "
"available on your PYTHONPATH environment variable? Did you "
"forget to activate a virtual environment?"
) from exc
# wrap pytest command here so we don't have to manage
# PYTHONPATH in multiple places. django-pytest unfortunately
# doesn't provide native management commands so we still need
# to invoke pytest directly
if len(sys.argv) > 1 and sys.argv[1] == "pytest":
pytest_args = " ".join(sys.argv[2:])
os.environ["PYTHONPATH"] = sys.path[0]
subprocess.run(f".venv/bin/pytest {pytest_args}", shell=True, env=os.environ)
else:
execute_from_command_line(sys.argv)
if __name__ == "__main__":
main()
This allow us to run pytest as:-
poetry run python manage.py pytest -s -x ./path/to/tests/test_*.py
