How can I tell which tests are passing and which are not?

Let me start by saying that I have done the rest of these tutorials on my own file system, rather than in the workspace. So it is very possible that the issue here stems from something I need to do differently to run the tests on workspaces instead of my own computer.

The readme file says that I can run the tests in the console using 'python manage.py tests'. Which, I figure I could use to comment out some of the tests, and check each one to see if it passes. First of all, running that returns an unknown command error. So I ran 'python manage.py test' instead, and I keep getting what I think is a database error. But since the code challenge only has me handle the three specific files, I have to assume that I'm not supposed to edit any other files, so I haven't. But I'm not sure what's going on with the database. Assuming that's the problem. Here's the error I get (it's long, but I figure it's better to include the whole thing):

treehouse:~/workspace/karaoke$ python manage.py test
Creating test database for alias 'default'...
Traceback (most recent call last):

The above exception was the direct cause of the following exception:
