Stubbing django settings with Mock
SOME_SETTING = 'some value'
from django.test import TestCase
from myapp.utils import get_some_setting
from mock import patch
class SimpleTest(TestCase):
# see http://www.voidspace.org.uk/python/mock/patch.html#where-to-patch
@patch('myapp.utils.settings', SOME_SETTING='FAKED!')
def test_get_some_setting_returns_some_setting(self, settings):
assert get_some_setting() == 'FAKED!'
from django.conf import settings
def get_some_setting():
return settings.SOME_SETTING

This article was very helpful for me.
Thank you!

But, that way overwrite entire "settings" variable in testing.
How about the following ways

from django.conf import settings
import myapp

def _get_some_setting():
    return settings.SOME_SETTING

def get_some_setting():
    return myapp.utils._get_some_setting()
@patch('myapp.utils._get_some_setting', return_value='FAKED!')

.. or, is there a better way?

I think since 1.4v better way:

from django.test.utils import override_settings

@override_settings(SOME_SETTING='some-data')
def test(self):

@pymen - unfortunately that approach doesn't work if you've already imported the value at the point of module load.

If mymodule has already been imported with the original settings, you don't get the @override_settings() update, and so the mock solution is a good workaround for this

Django 1.4 provides a decoraor @override_settings allows you mock Django settings.
So the recommended way is:

from django.test.utils import override_settings
...


class ABCTest(TestCase)

    @override_settings(DEBUG=False)
    def test_xyz(self):
        # do something
