Could the same thing be achieved by subclassing your base test class and then overriding setUp to inject the correct data for that combination? I'm pretty sure I'm oversimplifying, but I'm really interested in your method.

In Django, when we add a new field type, you need to remember to test all the integrations (admin, forms, migrations, etc) and that's not always done correctly. It'd be great if there were some easier method than just subclassing a template test class and implementing all tests from the ground up.

I do not think it would work with sub-classing. With the approach we have it is just easier to add the 'new' method name to test into the list argument of the meta class. The meta class would generate a `test` method with the passed in function name.

With the subclass approach you are required to implement a new class and essentially write repetitive code, or reuse existing functions. Reusing existing test methods does not provide good error reporting as I had stated earlier. It is late in the day. Shortly, I will try to post a gist example of what I am talking about, if you are still interested.

Bit late to respond, but yes I would be interested, thanks!
