Models inside test folder - Django 1.7 problem

[galozek]

Hi,

I'm trying to port my project to Django 1.7. Every goes fine except 1 problem with an abstract model testing.

Django 1.7 runs migrate command while testing. That means models not included in migrations are omitted. That's the issue I've got.

What I do in my /app/tests/ directory:

• I keep there a dummy model: class TestBaseImage(BaseImage): pass
  
• All it does is to inherit from the abstract BaseImage model.
  
• In my tests, when I try to create an instance of TestBaseImage I get DB error saying table does not exist

Is there any good way to make that work with new migration system? I don't want to include my dummy model in my migrations - that's obvious. I need a way to test that abstract model - it worked in Django 1.6 but with new migrations it doesn't.

Can you put the test model in its own models.py in a test-only "app",
and then include that test-only app in INSTALLED_APPS only when running
tests?

There is a long-time ticket requesting a cleaner way to do test-only
models: https://code.djangoproject.com/ticket/7835

The technique you were relying on wasn't documented and really only
worked by accident in previous Django versions.
