You really really do not need to be testing that Django's CRUD operations work - there is no value in doing so, since Django is well tested. Tests should concentrate on the custom business logic that your app uses, not that when you create an object in the database, an object exists in the database. As to your question, what DB backend are you using for tests? Each django.test.TestCase test is run inside a transaction that is rolled back[1]; if your backend "supports" transactions by ignoring them (cough, MySQL/MyISAM), then nothing happens when the transaction is rolled back.
