API Automation Testing with REST Assured

Software systems rely heavily on APIs to communicate, making API testing a critical skill for modern quality assurance. If you want to move beyond manual testing and automate your API verification process, learning how to write programmatic tests is the essential next step. This text-based course guides you through the fundamentals of API automation using REST Assured, the industry-standard Java library. You will transition from understanding basic HTTP requests to writing structured, automated test assertions that ensure your backend services perform exactly as expected. What you'll learn: Learn the fundamental concepts of REST APIs, HTTP methods, status codes, and headers; Configure a Java-based testing environment using modern dependency management tools; Write automated tests to send GET, POST, PUT, and DELETE requests with REST Assured; Validate complex JSON responses using path assertions and schema validation techniques; Handle modern authentication mechanisms, including Bearer tokens and basic auth; Organize your test cases using structured testing frameworks for better maintainability. The course starts with basic terminology and core HTTP concepts before guiding you through hands-on test scripts and assertion strategies. You will read detailed explanations, analyze clear code snippets, and complete written exercises designed to solidify your API testing skills. This course is designed for beginners to API testing and QA professionals who have a basic familiarity with Java and want to learn automation. No prior API testing experience is required.
