A less-massive hack would be to create your own TestSuiteRunner subclass and change a setting or do whatever else you need to for the rest of your application. You specify the test runner in your settings:

TEST_RUNNER = 'your.project.MyTestSuiteRunner'

In general, you don't want to do this, but it works if you absolutely need it.

from django.conf import settings
from django.test.simple import DjangoTestSuiteRunner

class MyTestSuiteRunner(DjangoTestSuiteRunner):
    def __init__(self, *args, **kwargs):
        settings.IM_IN_TEST_MODE = True
        super(MyTestSuiteRunner, self).__init__(*args, **kwargs)

NOTE: As of Django 1.8, DjangoTestSuiteRunner has been deprecated. You should use DiscoverRunner instead:

from django.conf import settings
from django.test.runner import DiscoverRunner


class MyTestSuiteRunner(DiscoverRunner):
    def __init__(self, *args, **kwargs):
        settings.IM_IN_TEST_MODE = True
        super(MyTestSuiteRunner, self).__init__(*args, **kwargs)
