Yep, lots of interaction tests that can be quite brittle and can take a long time to run, even with a farm of servers and consoles.

A lot of small and low level stuff can be unit tested but during production things like writing good tests falls through the cracks.

And game development usually involves a lot of iteration, so setting up tests is at best a waste of time, and at worst a crutch that hurts productivity.

The best benefit we've found for unit tests is in low level platform specific code and generic containers. Things of that nature which absolutely must work and can themselves be tested in isolation.

I'm sure when we finish the project and look back on it we can go in, clean up, and implement far more unit tests for the code we already have.
