5.8Key Takeaways

  • Test error paths as thoroughly as success paths
  • Error responses should be structured, informative, and free of internal details
  • Rate limiting must exist and must include Retry-After headers
  • Malformed requests should return 400, never 500
  • Parameterize environments so the same suite runs against dev, staging, and production
  • Tag destructive tests to prevent accidental data modification in production
