Game testing refers to the process of software testing for vieo games. The formal process, performed by professional game testers, begins well into game development, depending on the game's allotted budget for testing. High-budget flagship titles (called "AAA", pronounced "triple-A") may begin testing with the first playable alpha, while low-budget and casual games might not enter testing until a release candidate (RC) is ready. Professional game testing may involve general playtesting but should not be confused with "public betas" or "stress tests" in which players simply do as they please and report bugs that are found incidentally. Public releases such as these are almost certainly late betas or RCs.
