Unable to import 3 modules when running tests

[Mike Cameron]

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?

[Mike Cameron]

Also, I have re-created my virtualenv from scratch, but the error persists.

[Collin Anderson]

So there's no tracebacks for the error messages?

The test runner likes to search for tests in your current directory. Is trying to run code it shouldn't be running?

Hi Mike

I've had a similar problem and couldn't find much help online.

But finally found the cause of the problem.
Try this fix: https://bitbucket.org/cramm/django-sqlserver/commits/d3a4e28a2768cb7729e788087889bf32806dfffb

It's pretty much bypassing the import errors.

Hope it helps!
Cheers

Are you running on Windows? I noticed you are using django-mssql.

I'm having the same issue you are having - I'm using:

django 1.7

Python 2.7

Windows 7

django-mssql 1.6

I'm thinking it's either an issue with the windows install of django or with django-mssql
