After creating or editing documentation, use FastAPI with Sauce Labs to easily auto-generate (or update) OpenAPI spec files, API mock servers and bidirectional contract tests. Sauce Labs checks both the OAS spec file and the API's provider and consumer contract. Extend contract tests easily into automated API functional and load tests for your CI/CD pipeline. Reuse API tests as holistic functional performance monitors that give highly usable feedback and fast debugging in any environment.
