Configuring Django settings

There are a couple of different ways Django settings can be provided for the tests.

The environment variable DJANGO_SETTINGS_MODULE

Running the tests with DJANGO_SETTINGS_MODULE defined will find the Django settings the same way Django does by default.

Example:

$ export DJANGO_SETTINGS_MODULE=test_settings
$ pytest

or:

$ DJANGO_SETTINGS_MODULE=test_settings pytest

Command line option --ds=SETTINGS

Example:

$ pytest --ds=test_settings

pytest.ini settings

Example contents of pytest.ini:

[pytest]
DJANGO_SETTINGS_MODULE = test_settings

Order of choosing settings

When the command option –ds, the environment variable and the pytest.ini configuration is used at the same time, pytest-django will prefer using settings from the command line option –ds, then the environment variable and last the pytest.ini. You can use addopts = –ds=yourtestsettings in your pytest configuration to automatically add the –ds option.

Using django-configurations

There is support for using django-configurations.

To do so configure the settings class using an environment variable, the –dc flag, or pytest.ini DJANGO_CONFIGURATION.

Environment Variable:

$ export DJANGO_CONFIGURATION=MySettings
$ pytest

Command Line Option:

$ pytest --dc=MySettings

INI File Contents:

[pytest]
DJANGO_CONFIGURATION=MySettings

Using django.conf.settings.configure()

Django settings can be set up by calling django.conf.settings.configure().

This can be done from your project’s conftest.py file:

from django.conf import settings

def pytest_configure():
    settings.configure(DATABASES=...)
