Or am I doing it wrong?

I also tried using the instructions from:

And this looks fine at first sight, but when I add the following patch to check if the tests do actually run:

         config = [ 20, 50, 30, 40 ]
         seriesList = [range(max_val) for max_val in config]

The failure is not reported, inidicating this does not actually run the tests...

I'll close this one myself now, since by now I have figured out how to run them.

FYI:

$ cd webapp
$ python manage.py test --settings=tests.settings
