FAQ === .. _faq-import-error: 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 :ref:`managing_the_python_path_explicitly` for more information. How can I make sure that all my tests run with a specific locale? ----------------------------------------------------------------- Create a `pytest fixture `_ that is automatically run before each test case. To run all tests with the english locale, put the following code in your project's `conftest.py`_ file: .. code-block:: python from django.utils.translation import activate @pytest.fixture(autouse=True) def set_default_language(): activate('en') .. _conftest.py: http://docs.pytest.org/en/latest/plugins.html .. _faq-tests-not-being-picked-up: My tests are not being found. Why? ---------------------------------- By default, pytest looks for tests in files named ``test_*.py`` (note that this is not the same as ``test*.py``) and ``*_test.py``. If you have your tests in files with other names, they will not be collected. Note that Django's ``startapp`` manage command creates an ``app_dir/tests.py`` file. Also, it is common to put tests under ``app_dir/tests/views.py``, etc. To find those tests, create a ``pytest.ini`` file in your project root and add an appropriate ``python_files`` line to it: .. code-block:: ini [pytest] python_files = tests.py test_*.py *_tests.py See the `related pytest docs`_ for more details. When debugging test collection problems, the ``--collectonly`` flag and ``-rs`` (report skipped tests) can be helpful. .. _related pytest docs: http://docs.pytest.org/en/latest/example/pythoncollection.html#changing-naming-conventions 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 whether transactions are tested or not. .. _faq-getting-help: 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: .. code-block:: python 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) Add the path to this class in your Django settings: .. code-block:: python TEST_RUNNER = 'my_project.runner.PytestTestRunner' Usage: .. code-block:: bash ./manage.py test -- **Note**: the pytest-django command line options ``--ds`` and ``--dc`` are not compatible with this approach, you need to use the standard Django methods of setting the ``DJANGO_SETTINGS_MODULE``/``DJANGO_CONFIGURATION`` environmental variables or the ``--settings`` command line option. How can I give database access to all my tests without the `django_db` marker? ------------------------------------------------------------------------------ Create an autouse fixture and put it in ``conftest.py`` in your project root: .. code-block:: python @pytest.fixture(autouse=True) def enable_db_access_for_all_tests(db): pass How/where can I get help with pytest/pytest-django? --------------------------------------------------- Usage questions can be asked on StackOverflow with the `pytest tag`_. If you think you've found a bug or something that is wrong in the documentation, feel free to `open an issue on the GitHub project`_ for pytest-django.
