How to use this trainer
No backend or external AI is called. Your answer is scored locally against a structured QA checklist.
Cover affected users, baselines, frontend and backend latency, data volume, dependencies, release correlation, load tests, caching, observability, mitigations, and release gates.
Tip: a stronger answer usually mixes happy path, negative cases, state changes, data, backend, UX, accessibility, and risk.
