I am using django to build my website and I have used django-pytest to test my apps but I have got this error Note I am usign python 3.9

================================================================== warnings summary 

===================================================================

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

-- Docs: https://docs.pytest.org/en/stable/warnings.html

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

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.

    Hm. django-pytest/pytest-django is not the problem. It seems that pytest-django does not respect the DJANGO_SETTINGS_MODULE line in `pytest.ini`, despite the [docs say so](https://pytest-django.readthedocs.io/en/latest/tutorial.html#step-2-point-pytest-to-your-django-settings)... – nerdoc Aug 28 '21 at 14:23

    oh, @DIAA SHALABY, and you should remove the whitespace from `DJANGO_ SETTINGS_MODULE` – nerdoc Aug 28 '21 at 14:24

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

The warning

PytestConfigWarning: Unknown config option: some-name

means that the config option some-name is not known to pytest or any of the currently installed pytest plugins (just what the warning implies). In particular, here it means that either pytest-django is not installed, or it is not visible to pytest for some reason (e.g. you have installed pytest-django using the wrong pip command).

To troubleshoot, first list all installed plugins that pytest finds using pytest -VV:

$ pytest -VV
This is pytest version 6.2.5, imported from /private/tmp/so/lib/python3.9/site-packages/pytest/__init__.py
setuptools registered plugins:
  pytest-django-4.5.2 at /private/tmp/so/lib/python3.9/site-packages/pytest_django/plugin.py
  pytest-cov-3.0.0 at /private/tmp/so/lib/python3.9/site-packages/pytest_cov/plugin.py

Here, pytest reports that two plugins are found: pytest-cov and pytest-django.

Now, if pytest-django is not listed, check where it was installed by e.g. issuing pip show pytest-django and looking for the path under Location:

$ pip show pytest-django
...
Location: /private/tmp/so/lib/python3.9/site-packages

Or, if pip is not available for you, check where Python import pytest_django package from via

$ python -c 'import pytest_django; print(pytest_django.__path__[0])'
/private/tmp/so/lib/python3.9/site-packages/pytest_django

The paths to site-packages directory in both outputs should match. In this example, both pytest -VV and pip show pytest-django report /private/tmp/so/lib/python3.9/site-packages as the installation path. If those differ, reinstall pytest-django using the correct Python environment.

You should correct your pytest.ini file by removing spaces around =:

[pytest]
DJANGO_SETTINGS_MODULE=your_project_name.settings

Note: per Django structure, your project should have a subfolder with settings.py file in it. You need to point pytest to this file and use dot . instead of /.

Well, In my case I was having an entry py.test --ignore=outofscope in my pytest.ini file, which was causing that warning.

I solved my problem by updating my pytest.ini file.

  • look for any warning/error raised by your editor
  • remove any extra space when assigning some values
