How do you implement agentic AI for automated API contract testing?
API contract testing agents verify that API implementations conform to their published specifications. Configure agents with access to API specifications like OpenAPI or GraphQL schemas, and running API instances. The agent generates test cases that validate every endpoint against its contract including request validation, response schema conformance, status code correctness, and error response formats. Implement producer-side testing that verifies the API meets its published contract and consumer-side testing that verifies consumer expectations match the contract. Detect breaking changes by comparing current behavior against previous contract versions. Generate contract compliance reports with specific violation details. Support contract-first development by validating implementations against specifications before deployment.
