I see an error saying “could not import myproject.settings”¶
pytest-django tries to automatically add your project to the Python path by
looking for a
manage.py file and adding its path to the Python path.
If this for some reason fails for you, you have to manage your Python paths explicitly. See the documentation on Managing the Python path explicitly for more information.
How can I make sure that all my tests run with a specific locale?¶
from django.utils.translation import activate @pytest.fixture(autouse=True) def set_default_language(): activate('en')
My tests are not being found. Why not?¶
By default, pytest looks for tests in files named
test_*.py(note that this is not the same as
test*.py). If you have your tests in files with other names, they will not be collected. It is common to put tests under
app_directory/tests/views.py. To find those tests, create a
pytest.inifile in your project root with the contents:[pytest] python_files=*.py
When debugging test collection problems, the
--collectonly flag and
(report skipped tests) can be helpful.
Does pytest-django work with the pytest-xdist plugin?¶
Yes. pytest-django supports running tests in parallel with pytest-xdist. Each process created by xdist gets its own separate database that is used for the tests. This ensures that each test can run independently, regardless of wheter transactions are tested or not.
How can I use
manage.py test with pytest-django?¶
pytest-django is designed to work with the
pytest command, but if you
really need integration with
manage.py test, you can create a simple
test runner like this:
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.failfast: argv.append('--exitfirst') if self.keepdb: argv.append('--reuse-db') argv.extend(test_labels) return pytest.main(argv)
Add the path to this class in your Django settings:
TEST_RUNNER = 'my_project.runner.PyTestRunner'
./manage.py test <django args> -- <pytest args>
Note: the pytest-django command line options
--dc are not
compatible with this approach, you need to use the standard Django methods of
variables or the
--settings command line option.
How/where can I get help with pytest/pytest-django?¶
