Those of you that do Game Development, how many of you are also doing TDD (Test Driven Development) as part of the process?
I've recently made a promise to myself that I would start doing more TDD in my projects (ok ok, doing "any" would qualify as more, technically...) and I find myself at a loss for what to actually test.
It seems easier in traditional projects, but in game development where you rely on random things and generated things and player input things, I'm curious what you (those of you that do it) choose to test.
Please share your stories in the comments section. Thanks!
