Automating Contract Tests

  1. Paste Spec: Input your OpenAPI/Swagger specification (JSON or YAML).
  2. Analyze: The AI parses the spec to understand expected request/response structures.
  3. Generate: Create automated test cases (e.g., using Jest or Supertest) to validate the contract.
  4. Validate: (Optional) Paste an actual API response to check for immediate schema violations.

Prevent Breaking Changes

Ensure your API implementation always matches the documentation. Catch drift before it reaches production.
