API Testing and Automation with Postman

In modern software development, ensuring the reliability of web services through robust API testing is a critical skill. This text-based course guides you through the process of designing, executing, and automating API tests without needing complex coding setups. You will transition from manual API calling to building fully automated, structured test suites. You will learn to validate responses, manage dynamic data across environments, and run your tests from the command line for continuous integration. What you'll learn: Understand foundational API concepts, HTTP methods, status codes, and JSON response structures; Create and organize structured request collections in Postman for systematic testing; Write automated test scripts using JavaScript assertions to validate response payloads and schemas; Manage dynamic variables and environment configurations to test across different stages; Configure mock servers to simulate API behaviors during development; Execute automated test suites from the command line using Newman. The course starts with fundamental API concepts and Postman interface basics before moving into script writing, environment management, and command-line automation. Through clear written explanations and practical code examples, you will build a solid foundation in test automation. Designed for QA engineers, developers, and tech enthusiasts new to API testing, this course requires no prior automation experience. Start your journey toward efficient, automated API testing today.
