Once I wrote my third game in Unity, with unit tests coverage of about 80%. It was least buggy game in my entire career. It was also the hardest time as I had to start thinking more about creating testable components rather than messy spaghetti code I used to write before.

I’ve found that while I did spend a lot of time at first figuring out how to write testable code, I now am so much better at writing in this way that I am much more productive since everything has great test coverage. Saves me going back to modules I wrote 2 years ago to add features.

This is one of the best "side-effects" of testing, with the reasoning is that testable code is good code (as in modular, cohesive, etc...)

Since testing in game development is very much underrated, it would be interesting to hear more about this. Was this just as a hobby or is the game available somewhere? And have you ever done a demo/talk about how you've approached unit testing with Unity?

Games are likely to benefit significantly from unit tests: architecture is complex and likely to be improved by adding clean boundaries and layers for the sake of testability; supporting automation is likely to enable useful features (e.g. deterministic simulations); tests are likely to be meaningful and important.

  Have you developed games at all, or are you just speaking from an armchair?

    As a gamedev who writes unit tests, I agree with GP. Games benefit from unit tests. That, however, doesn't change the systemic incentives that prevent tests from being written. The ways that gamedev is budgeted/funded is a more important factor than more tests = a more stable/less buggy game.

      What engine do you use that supports a unit test framework?
