Unit testing with django-celery?

Question

I am trying to come up with a testing methodology for our django-celery project. I have read the notes in the documentation, but it didn\'t give me a good idea of what to a

I like to use the override_settings decorator on tests which need celery results to complete.

from django.test import TestCase
from django.test.utils import override_settings
from myapp.tasks import mytask

class AddTestCase(TestCase):

    @override_settings(CELERY_EAGER_PROPAGATES_EXCEPTIONS=True,
                       CELERY_ALWAYS_EAGER=True,
                       BROKER_BACKEND='memory')
    def test_mytask(self):
        result = mytask.delay()
        self.assertTrue(result.successful())

If you want to apply this to all tests you can use the celery test runner as described at http://docs.celeryproject.org/en/2.5/django/unit-testing.html which basically sets these same settings except (BROKER_BACKEND = 'memory').

In settings:

TEST_RUNNER = 'djcelery.contrib.test_runner.CeleryTestSuiteRunner'

Look at the source for CeleryTestSuiteRunner and it's pretty clear what's happening.
