Pure-reference catalog of the testing categories that apply to a video-game build before it ships. Defines the six canonical buckets the industry tests against - functional / compliance / compatibility / performance / localization / accessibility - plus the multiplayer and content-rating sub-axes. Cross-references each bucket to the platform-holder vocabulary that drives it (Microsoft Xbox Requirements / XR test cases, Sony TRC, Nintendo Lotcheck, Steam Direct review). Use as the taxonomy lookup when planning a game test pass, scoping QA effort, or mapping platform-cert findings back to internal test categories.
