  c:\users\eng_diaa_shalaby\desktop\unittest\venv\lib\site-packages\_pytest\config\__init__.py:1233: PytestConfigWarning: Unknown config option: DJANGO_
SETTINGS_MODULE

    self._warn_or_fail_if_strict(f"Unknown config option: {key}\n")

This is my pytest.ini file content

# -- FILE: pytest.ini (or tox.ini)
[pytest]
DJANGO_SETTINGS_MODULE = testing_settings
# -- recommended but optional:
python_files = tests.py test_*.py *_tests.py

and I run this command

pytest

and this is my venv packages

Answer 1

The accepted answer it's not answering OP question neither providing solution.

I have encountered the same problem, I'm using Django 4.0 and Pytest 7.2.1

I'm using pytest.ini as configuration file.

Solution:

[tool:pytest]
DJANGO_SETTINGS_MODULE = core.settings.local
python_files = test_*.py

Adding keyword tool solves the problem.

Another thing that might be necessary is adding ENV variable:

export DJANGO_SETTINGS_MODULE=mysite.settings 

Answer 2

I found out what was the reason for my problem. I just uninstall

django-pytest 0.2.0

and install

pytest-django

instead by running the following command

pip install pytest-django

and run the following command after pip installed pytest-django

set DJANGO_SETTINGS_MODULE=testing.settings

And everything just works fine.
