Getting started with pytest and pytest-django¶
pytest and pytest-django are compatible with standard Django test suites and Nose test suites. They should be able to pick up and run existing tests without any or little configuration. This section describes how to get started quickly.

Step 1: Installation¶
pytest-django can be obtained directly from PyPI, and can be installed with
pip install pytest-django
Installing pytest-django will also automatically install the latest version of
pytest‘s plugin system and can be used right away
after installation, there is nothing more to configure.
Step 2: Point pytest to your Django settings¶
You need to tell pytest which Django settings that should be used for test runs. The easiest way to achieve this is to create a pytest configuration file with this information.
Create a file called
pytest.ini in your project root directory that contains:
You can also specify your Django settings by setting the
DJANGO_SETTINGS_MODULE environment variable or specifying the
--ds=yourproject.settings command line flag when running the tests. See the
full documentation on Configuring Django settings.
Step 3: Run your test suite¶
Tests are invoked directly with the
pytest command, instead of
test, that you might be used to:
Do you have problems with pytest not finding your code? See the FAQ I see an error saying “could not import myproject.settings”.
The Usage and invocations section describes more ways to interact with your test suites.
pytest-django also provides some Django helpers to make it easier to write Django tests.
Consult the pytest documentation for more information in pytest itself.
