I've only done a small amount of Unity and didn't do any TDD there (I know, my bad), but I would take the same approach I would if it was a Swing or Android app - move as much code as possible to be agnostic of the infrastructure it is running in and test that in isolation.
I would have a series of ports, a la ports/adapters, that allow the domain logic to communicate to/from the Unity layer and have the domain logic only be aware of those, then provide adapters into Unity.? The biggest downside I see from this is that it will undoubtedly bloat your code and could _potentially_ have a performance impact depending on the type of game you're making.
?
Yes, I was just testing stuff I was delegating to. Not grasping the thorny MonoBehaviour.
I did see somewhere that Model-View-Controller and Dependency Injection could let you TDD into MonoBehaviour sub-classes.
Quite a good discussion here:

I have no idea about how Unity works, but perhaps instead of writing your behaviour in a class that extends monobehavior, you could create a pure-C# object and delegate all interesting stuff to it.

How do you make classes that extend monobehavior testable? Or maybe I'm just not far enough into the project where I can use composition on those bits.

Avi - nice to see you're still out there :-) I've played around a bit with Unity and took the weak position vis-¨¤-vis TDD.
That is: the visual interface is tested by looking at it and the rest is just normal C# code with normal tests.
