django-override-settings Description

Provide a way to override Django's settings when running tests django-override-settings is a Django app that 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(SETTING_DELETED) to run tests without a given setting defined.The functionality in this package will eventually be superseded when Django 1.4 is released as it will come with a built-in override_settings.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.InstallationWe're on PyPI:pip install django-override-settingsUsageIf 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 settingsfrom django.test import TestCasefrom override_settings import override_settings@override_settings(FOO="abc")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:@override_settings(BAR="123")class TestBar(TestCase): @override_settings(BAR="abc") 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): @override_settings(BAR="123") 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_appsclass TestAppModifiers(TestCase): @with_apps('django.contrib.humanize') def test_humanize(self): # ... @without_apps('django.contrib.sites') def test_no_sites(self): # ...To run tests without a setting, use SETTING_DELETED:from override_settings import override_settings, SETTING_DELETEDclass TestMissingSetting(TestCase): @override_settings(CUSTOM_OPTION=SETTING_DELETED) def test_delete_custom_option(self): """ Useful to make sure a missing setting raises an Exception. """ self.assertRaises(AttributeError, getattr, settings, 'CUSTOM_OPTION') Requirements: · Python · Django
