I found what i was looking for:
self.assertFormError(res, 'form', 'username', 'This field is requied.')
As simple as that.
Just in the case one of the website admins reads here.
An example to that Method, besides an large test example
is provided under:
http://www.djangoproject.com/documentation/models/test_client/
But then i click on documentation and then go to the
apropriate test section i come to:
http://docs.djangoproject.com/en/dev/topics/testing/#assertions
which doesn't provide a link to the large example.
Providing that link would be really cool :-)
