Not many games testers here, it’s often not paying at the pro level. I once went through a Sony interview, they have all kinds of tooling for testing, it’s very much engine specific stuff that gets tested and how it gets tested is not always in ways players expect. The tooling is where the buck are as far I could see.
See Game Testing 2023 . It does not really work like that IRL. Releases are staggered and publishers rely on free testing they get from beta testers who sign an NDA in return for early drops. And mechanically, in house testers use all kinds of tooling to help them set up the scenarios and actually don’t end up doing such crazy analysis at the user exposed surfaces, the engine itself is where the logic lies, it’s easier to test there, not by actually playing.
