I'm not sure what you tried here -- using a TestCase subclass as a layer? That won't work, by design -- layers aren't test cases, they are just a way to organize and share fixtures among test cases. I'm not sure what it would mean to have a layer that was also a test case. Would that mean the tests in the layer also get executed? IMO that's confusing and unnecessary and so I think the behavior here is correct.

So how do you cause a layer to use Django TransactionTestCase features when you use Such instead of the classic TestCase?

Perhaps we should provide layers that fit Django's test framework functionality. I'm not very fond of the idea since it's a maintenance burden to copy/paste the code with each Django release and it certainly won't support multiple Django versions.

I think django-nose2 would be the right place for layer support to be added. And/or maybe Such could be extended to support passing an optional TestCase class into createTests?
