Test specific models in Django

Is it possible to have a set of models just for testing purposes? The idea is that I've written an app that contains some h开发者_开发问答elper abstract model HelperBase. Now I'd like to provide some models that would inherit from it in order to test it, say DerivedTest1, DerivedTest2. However I wouldn't really like those test models to appear in the production database in the end. I just want their tables to be constructed in the test database. Is it possible and if so - how to do it? I've already tried creating models in the tests.py file but this doesn't seem to work.

You could try creating a whole new app that you only use on your development server.

E.g., if your app is called myapp you would call your testing app myapp_test.

Then in myapp_test's models.py you would from myapp import models and then subclass your models in there.

Then in your settings.py you either just try and remember to comment out the myapp_test application from INSTALLED_APPS when deploying to your production server. Or you can use the local_settings.py methodology to only have the myapp_test included in INSTALLED_APPS on your test machine.
