Tests do not run without django-configuration installed.

[jakubjanuzik]

In my project I do not use django-configuration as I don't really need it.

When installing pytest-django I try to run my tests, here's what I've got:

pytest

ModuleNotFoundError: No module named 'configurations'

Also my package versions:

pytest==5.3.1
pytest-django==3.3.0
pytest-factoryboy==2.0.3

Is django-configuration required? I couldn't find any information about it in the documentation.

[blueyed]

I think it should work without it.

Something appears to trigger the import for you though:

pytest-django/pytest_django/plugin.py

Lines 312 to 328 in 00e7bee

	# Configure DJANGO_CONFIGURATION
	dc = (
	options.dc
	or os.environ.get(CONFIGURATION_ENV)
	or early_config.getini(CONFIGURATION_ENV)
	)
	if ds:
	os.environ[SETTINGS_MODULE_ENV] = ds
	if dc:
	os.environ[CONFIGURATION_ENV] = dc
	# Install the django-configurations importer
	import configurations.importer
	configurations.importer.install()

(also your line number is very different, so please try the latest release / master branch)

I think a fix would be to ignore/handle the ImportError here though, too.

I do have set DJANGO_SETTINGS_MODULE in my pytest.ini, could this be the cause?

cat pytest.ini 
[pytest]
DJANGO_SETTINGS_MODULE = mobigol.test_settings
python_files = tests.py test_*.py *_tests.py

test_settings.py (just to have separate file for now).

from .settings import *

Updated the lib:

pytest==5.3.1
pytest-django==3.7.0
pytest-factoryboy==2.0.3

But the error still happens:

The line number seems to be correct this time though.

[blueyed]

Can you check which of the options triggers it, please?

pytest-django/pytest_django/plugin.py

Lines 313 to 317 in 00e7bee

	dc = (
	options.dc
	or os.environ.get(CONFIGURATION_ENV)
	or early_config.getini(CONFIGURATION_ENV)
	)

(using pdb or just print)

I do have set DJANGO_SETTINGS_MODULE in my pytest.ini, could this be the cause?

Shouldn't be an issue.

[jakubjanuzik]

I found the cause, in my another project (from the job) we use Django-Configurations and I had set DJANGO_CONFIGURATION environment variable. That probably triggered the django-configurations for pytest.

After I unset that, everything works as supposed to.

Thanks for help and sorry for confusion and taking your time

[blueyed]

I've thought about handling the ImportError there better, but e.g. turning it into a pytest.UsageError is not really that helpful either.
Instead I've thought that the "configuration" being used should be reported (similar to settings): #791.
What do you think?

[jmarrec]

I know it's 5 years later, but I stumbled upon this issue while googling, so in the hope that it serves for someone else:

I had copied the pyproject.toml from a project where I did use django-configuration. And the issue was that it had an incorrect --ds argument

[tool.pytest.ini_options]
-addopts = "--ds=config.settings.test --reuse-db --import-mode=importlib"
+addopts = "--ds=myproject.settings --reuse-db --import-mode=importlib"
