The key thing is to know when to rely on Django's own tests, and when to write your own. There's absolutely no point, for example, to write tests that check that you can instantiate and save a model, and that the values in the database match the values you pass in. That's covered entirely by Django, and is very well-tested. So what your unit tests need to cover is the bits where your code interacts with and builds on the things that Django provides - ie the business logic. This can be in custom model methods, or in views, or library modules. Personally, I always have trouble separating functional testing from unit testing, so my so-called unit tests seem to always end up using the test client to get a page and checking to see if it contains the right data. That's certainly a *part* of unit testing, but you also need to break things down to smaller units so you can test individual bits of logic, and this is very difficult to do right. -- DR. --~--~---------~--~----~------------~-------~--~----~ You received this message because you are subscribed to the Google Groups "Django users" group.
