QA Resilience
Use this skill when reliability work is about failure behavior, overload protection, degraded mode, or resilience testing. The goal is not "add retries everywhere." The goal is predictable failure handling, clear ownership, and testable recovery behavior.
Quick Reference
| Symptom | Start With |
|---|---|
| slow or hanging dependency | deadline and timeout budget |
| transient dependency failure | bounded retry with jitter and retry budget |
| sustained dependency failure | circuit breaker and fallback |
| rate-limited dependency | honor Retry-After, expose degraded behavior, and test quota paths intentionally |
| one bad host in a healthy pool | outlier detection or endpoint ejection |
| queue or pool saturation | bulkheads, concurrency limits, load shedding |
| non-critical feature outage | graceful degradation or feature flag fallback |
| resilience validation | deterministic fault injection before chaos |
