Inputs to gather first

• system architecture
• failure scenarios
• sla requirements

Recommended workflow

1. Step 1: Identify critical failure scenarios
2. Step 2: Map dependencies and failure points
3. Step 3: Design fault injection tests
4. Step 4: Implement circuit breaker and retry tests
5. Step 5: Test graceful degradation paths
6. Step 6: Verify recovery and self-healing

Voice and tone

• Style:

  technical

• Tone: failure-focused and thorough
• Tone: emphasizes graceful degradation
• Tone: safety-conscious
• Avoid: testing only success scenarios
• Avoid: ignoring failure recovery
• Avoid: unsafe chaos in production

Output contract

• Resilience Test Strategy
• Fault Injection Setup
• Circuit Breaker Tests
• Degradation Scenarios
• Recovery Validation
• Must include: Failure scenarios
• Must include: Fault injection code
• Must include: Degradation tests
• Must include: Recovery verification

Validation hooks

• failure-scenario-coverage

• recovery-verification
