In my prior (non-game) work experience I would hear how engineers would speak about their respective code bases. It was a lot of work but the engineers generally loved the services / code bases / etc that were built ground up with high unit test coverage, CI/CD and various forms of test automation.
Test automation feels very challenging in something like a game where there is a lot of “state” and so much of the game contains assets besides code. I’d love to see some examples of how to do even some basic automation in unity.
One possible suggestion is to take an existing course that already is part of GameDevTV and show how one would add test automation to it.
