Intro to Harry Percival, his background and story of how he got into TDD and ended up writing a book (http://amzn.to/1SqW1t3)
Comparing using unittest and pytest with applicability to testing django projects.
Functional end to end testing with selenium.
The django test client for middle level tests.
test isolation
django and isolated unit tests

Update: Comment from Harry Percival on 19-Jan-2014
I might have been a bit down on unit tests vs functional tests in that "unit tests never fail comment".
Not true at all, particularly as we've just been thru upgrading django on our core system, and the unit tests really saved our bacon on that one...
