Unable to import 3 modules when running tests

I'm doing python manage.py test, but always receive one of the following ImportError messages.

ImportError: No module named 'expressions_regress'  ImportError: No module named 'aggregation'  ImportError: No module named 'migrations'

I have ensured my virtual environment is enabled. I'm on Django 1.7.

Here is my settings.py

Also, for some strange reason Googling all 3 errors I'm getting yields nothing of value.

How can I resolve this?
