My API Testing & Postman Automation Journey with Gradific API

The author undertook an API testing and presentation task using the Gradific REST API documentation, focusing on advanced API testing concepts. The task involved reviewing the documentation and selecting four resources, including authentication, for full CRUD operations. They created 80 total test cases, a Postman collection, and professional documentation files. Initial challenges included authentication issues, leading to the discovery of the need for JWT tokens. To overcome this, the author learned to authenticate first, retrieve a token, and add it to every request header. They utilized Postman, HTTP headers, status code validation, API documentation, and test documentation to complete the project. The deliverables included a full Postman collection, detailed test scenarios, and functional authentication testing across the selected resources. This experience boosted their understanding of backend dependencies and API automation. Key takeaways highlighted the importance of validating authentication, comprehensive test cases, and clear documentation. The author expressed their enthusiasm for QA engineering and backend testing, offering helpful advice for API testing. They plan to continue developing their skills in Postman, automation scripts, and CI pipelines.
