Chaos Engineering for QA: deliberately breaking the system to test resilience
Resilience you never tested with a deliberate failure is an assumption, not a fact. Chaos Engineering for QA: the steady-state hypothesis, blast radius and the abort button, what failures to inject (instance kill, latency, dependency outage, resource exhaustion, zone outage), tools (Chaos Monkey, Gremlin, Chaos Mesh, AWS FIS, Toxiproxy), Game Days, the QA role (graceful degradation, retries, circuit breakers, observability) and a safe-experiment checklist.
