Contract testing validates that your API implementation matches consumer expectations by comparing actual responses against agreed contracts. This Skill provides patterns for REST and GraphQL contract validation, including schema verification and consumer-focused assertions across microservices.

Integrate automated API tests into CI/CD by validating schemas, checking authentication, and monitoring for contract drift. This Skill covers patterns for REST, GraphQL, and contract-based testing that detect breaking changes before deployment.

Comprehensive API testing requires validating error responses, input validation, authentication checks, idempotency guarantees, and concurrency behavior. This Skill provides patterns for all these scenarios across REST and GraphQL endpoints.

Yes. Contract testing detects when provider APIs diverge from consumer expectations. This Skill includes production monitoring patterns and schema validation strategies to identify and prevent contract drift across microservices.

Test consumer contracts, input and authentication validation, error handling, schema compliance, and idempotency. This Skill provides integration patterns for external dependencies and microservices to ensure robust API interactions.
