Having never worked at a gaming company but having a friend who was the head of testing at one very recognizable shop, the answer was definitely no, at least not there. Its definitely a big enough industry that I'm sure some does though.

Also, last time I wrote any 3D code, it at least appeared to be incredibly hard to test that some visual thing was just so. Of course there are still things like business logic that surely could be tested, but it's just not going to be as straight forward as having some code generate some HTML string and then asserting things against it. Those last-mile things you might want to test are always a challenge IMHO.

I learned a lot of my coding chops at a Rails shop that was very in to testing, so that's definitely my perspective, YMMV.
