I also write model tests using unsaved models where possible. I don't think it has significant test isolation benefits (your tests are still integrating with most of the ORM), but it does have test-suite speed benefits! I understand why the change was made in 1.8 to disallow assigning an unsaved object to a ForeignKey/OneToOneField attribute; in production code that would almost always be a bug. Personally, though, I've never been bitten by that bug, I'm confident I could easily find and fix such a bug if I did write it, and I don't want to give up the ability to use related unsaved models in tests. So I just use my own subclasses of ForeignKey and OneToOneField with `allow_unsaved_instance_assignment = True` set on them (essentially reverting the safety change in 1.8). I haven't attempted to switch it on dynamically for testing; that should be possible using a setting and a custom subclass, but I wouldn't choose to do that; differences between test and production behavior should be minimized.
