Best for

  • Design controlled API latency injection experiments for microservices resilience testing
  • Implement circuit breaker validation using fault injection on payment gateway dependencies
  • Create GameDay scenarios with cascading API failures to test system recovery mechanisms
  • Build automated chaos experiments for third-party API timeout and error response handling
  • Validate graceful degradation patterns when critical authentication services become unavailable

What you'll get

  • Structured experiment catalog with specific latency injection scenarios (500ms to 30s delays), expected system responses, and automated monitoring thresholds for each API dependency tier
  • GameDay runbook detailing cascading failure simulation sequence with precise abort conditions, rollback procedures, and real-time observability dashboard configurations
  • Circuit breaker validation framework with progressive failure rate injection (10%, 25%, 50%) including hypothesis statements and measurable success criteria for each experiment phase
Not designed for ↓
  • ×Production incident response or real-time debugging of live API failures
  • ×Load testing or performance benchmarking of API endpoints under normal conditions
  • ×Security penetration testing or vulnerability assessment of API endpoints
  • ×API design or development of new endpoints and integration patterns
Expects

Detailed system architecture documentation including API dependency mappings, current baseline performance metrics, and defined business impact thresholds for controlled failure experiments.

Returns

Structured experiment plans with specific failure injection scenarios, measurable success criteria, automated abort conditions, and detailed runbooks for safe execution and immediate rollback.
