Django test runner not finding tests

I had the same issue but my root cause was different.

I was getting Ran 0 tests, as OP.

But it turns out the test methods inside your test class must start with keyword test to run.

Example:

from django.test import TestCase


class FooTest(TestCase):
    def setUp(self):
        pass

    def tearDown(self):
        pass

    def this_wont_run(self):
        print 'Fail'

    def test_this_will(self):
        print 'Win'

Also the files with your TestCases in them have to start with test.
