django: failing tests from django.contrib.auth

Question

When I run my django test I get following errors, that are outside of my test suite:

AssertionError: 302 != 200

Could anyone explain me, what am I doing wrong or what I should set to get those tests pass?

Answer 1

I have managed to reproduce the test results you are seeing by doing the following:

MIDDLEWARE_CLASSES = (
    'django.middleware.cache.UpdateCacheMiddleware',
    .... <your middleware classes> ....
    'django.middleware.cache.FetchFromCacheMiddleware',
)

If you have these lines, try removing them and re-running the unit test. I do not however have a solution for this.
