A sufficiently big game in an established genre with in-house engine and expansions has several levels of automatic tests.

In my experience, such games only have manual testing, done by the people who bought the game.

My experience is from working on one of the games with automatic tests.

From the playing experience: yes, there are way more games with internal manual and external community testing.

Yeah at a certain level game productions will usually have automatic “smoke” tests for general build stability and I’ve worked on one that had automatic feature tests with replayed input. These were generally useful for catching obvious crashes and regressions, but the overhead only makes sense for a certain level of production. Could also see, and have heard of, more rigorous functional testing of things like a procedural generation pipeline that are otherwise harder to get sufficient coverage of manually.
