Paul Speed probably has the argument that unit testing doesn't help as the bugs evolve around the code that isn't unit tested.
I think that's a good thing then, we'll only have to ensure that the most important code is tested.
For instance I think raycasting and other scenegraph related things could make a good use of tests.
e.g. we had a bug where the returned bounding box was "null".
Raycasting a specific geometry and/or terrrain should be deterministic as should be the bounding box calculation, general transforms etc.

transformsetc.There are probably quite a few other ways.
