django-override-settings 1.1

Provide a way to override Django's settings when running tests

Latest Version: 1.2

django-override-settings provides an easy way to override settings in Django tests.

The override_settings class can be used as either a class or method decorator or as a context manager to temporarily override the values of settings. After each test case has finished (when using it as a decorator) or after the context manager has exited, it resets the values in django.conf.settings to what they were before. This prevents side-effects from creeping and lets each test case run in its own sandbox.

This package also provides two convenience functions (with_apps and without_apps) to modify just INSTALLED_APPS as well as a special object (SETTING_DELETED) to run tests without a given setting defined.

The functionality in this package will eventually be superseded when Django 1.4 is released as it will come with a built-in override_settings. But for those maintaining pre-1.4 codebases, hopefully this package comes in handy.


We’re on PyPI:

pip install django-override-settings


If you have a bunch of tests that require a given setting, you can decorate the class and each test case will use that value. For example:

from django.conf import settings
from django.test import TestCase
from override_settings import override_settings

class TestFoo(TestCase):
    def test_foo(self):
        self.assertEqual(settings.FOO, "abc")

Or you can decorate a single test case and have it only apply on that method:

class TestBar(TestCase):

    def test_bar(self):
        self.assertEqual(settings.BAR, "abc")

    def test_bar_no_decoration(self):
        self.assertEqual(settings.BAR, "123")

You can also use it as a context manager:

class TestBar(TestCase):
    def test_bar(self):
        self.assertEqual(settings.BAR, "123")

        with override_settings(BAR="abc")
            self.assertEqual(settings.BAR, "abc")

        self.assertEqual(settings.BAR, "123")

To modify just INSTALLED_APPS, use with_apps or without_apps:

from override_settings import with_apps, without_apps

class TestAppModifiers(TestCase):
    def test_humanize(self):
        # ...

    def test_no_sites(self):
        # ...

To run tests without a setting, use SETTING_DELETED:

from override_settings import override_settings, SETTING_DELETED

class TestMissingSetting(TestCase):
    def test_delete_custom_option(self):
        Useful to make sure a missing setting raises an Exception.
        self.assertRaises(AttributeError, getattr, settings, 'CUSTOM_OPTION')
