How do you automate REST APIs using TOSCA?

Automating REST APIs using TOSCA involves leveraging its API Scan and API TestCase Design capabilities. First, import the REST API definition using Swagger or OpenAPI into TOSCA. TOSCA automatically creates reusable modules for endpoints, methods, headers, and payloads. You can then design test cases by parameterizing requests, validating responses, and asserting status codes without heavy scripting. TOSCA also supports data-driven testing and CI/CD integration for continuous API validation. Learning this approach through a TOSCA Certification Course helps testers and QA professionals efficiently automate API testing and ensure consistent service quality across applications.
