Django test client response context None

Question

I have moved my Django app from my development machine (OS X, Python 2.6.5, Django 1.2.3) to a staging server (Ubuntu VM, Python 2.6.6, Django 1.2.3).

If I now run my test suite on the staging server, two tests fail when using the Django TestClient because response.context is None (but response.content is correct).

For example:

self.assertEquals(self.session.pk, response.context['db_session'].pk)

These test cases pass on the development machine.

Has anybody encountered similar problems?

Answer 1

You need to add the test setup statement.

import django
django.test.utils.setup_test_environment()

Answer 2

From Django documentation:

Although * your code * [+] would work in the Python interactive interpreter, some of the test client's functionality, notably the template-related functionality, is only available while tests are running. The reason for this is that Django's test runner performs a bit of black magic in order to determine which template was loaded by a given view. This black magic (essentially a patching of Django's template system in memory) only happens during test running.

So if you run it in a test run, it should work.
