I have a Django project in which certain environment variables are set in manage.py which later serve as the values defined in settings.py. Therefore, in order to run pytest-django, I'd like to run manage.py first.
I'm trying to follow the instructions in https://pytest-django.readthedocs.io/en/latest/faq.html#how-can-i-use-manage-py-test-with-pytest-django, but I'm running into an unexpected error. I have the following directory structure:
.
├── lucy
│ ├── settings
│ ├── base.py
│ ├── development.py
│ ├── production.py
│ └── staging.py
│ ├── staticfiles
│ ├── urls.py
│ └── wsgi.py
├── lucy_web
│ ├── __init__.py
│ ├── actions.py
│ ├── admin

│ ├── serializers.py
│ ├── static
│ ├── templates
│ ├── templatetags
│ ├── tests
│ ├── urls.py
│ └── views
├── manage.py
├── pytest.ini
The contents of runner.py are taken exactly from the FAQ:
class PytestTestRunner(object):
"""Runs pytest to discover and run tests."""
def __init__(self, verbosity=1, failfast=False, keepdb=False, **kwargs):
self.verbosity = verbosity
self.failfast = failfast
self.keepdb = keepdb
def run_tests(self, test_labels):
"""Run pytest and return the exitcode.
It translates some of Django's test command option to pytest's.
"""
import pytest
argv = []
if self.verbosity == 0:
argv.append('--quiet')
if self.verbosity == 2:
argv.append('--verbose')
if self.verbosity == 3:
argv.append('-vv')
if self.failfast:
argv.append('--exitfirst')
if self.keepdb:
argv.append('--reuse-db')
argv.extend(test_labels)
return pytest.main(argv)
Finally, in lucy/settings/base.py I add the following line:
TEST_RUNNER = 'lucy_web.runner.PytestTestRunner'
Finally, the pytest.ini file is as in the example in the docs:
# -- FILE: pytest.ini (or tox.ini)
[pytest]
DJANGO_SETTINGS_MODULE = lucy.settings.production
# -- recommended but optional:
python_files = tests.py test_*.py *_tests.py
The problem is that pytest doesn't seem able to find the tests. If I run the command
python manage.py test lucy_web.tests
I get
(venv) Kurts-MacBook-Pro:lucy-web kurtpeek$ python manage.py test lucy_web.tests
============================================ test session starts ============================================

======================================= no tests ran in 0.00 seconds ========================================
ERROR: file not found: lucy_web.tests
However, if I comment out the TEST_RUNNER line in base.py and run the same command, the tests run successfully:
(venv) Kurts-MacBook-Pro:lucy-web kurtpeek$ python manage.py test lucy_web.tests

What am I doing wrong here? Do I need to put runner.py in a different location?
