Django unit test client response has empty context

Today I run into the same issue. The second test gets same page has nothing in response.context

I made a research and found that 1) test client uses signals to populate context, 2) my view method is not called for the second test

I turned on a debugger and found that the guilty one is 'Cache middleware'. Knowing that I found this ticket and this SO question (the latter has a solution).

So, in short: the second request is served from cache, not from a view, thus a view is not executed and test-client doesn't get the signal and have no ability to populate context.

I can not disable cache middleware for my project, so I added next hack-lines into my settings:

if 'test' in sys.argv:
   CACHE_MIDDLEWARE_SECONDS = 0

Hope this helps someone

It's because you ran into some error, exited the shell and restarted it.

But you forgot to start environment...

from django.test.utils import setup_test_environment
>>> setup_test_environment()

That was my problem. Hope it works...
