REST API Automation Testing with REST Assured

As modern software architectures shift toward microservices, knowing how to automate API testing is an essential skill for quality assurance professionals. This course provides a clear, text-based path to mastering API automation without needing prior testing experience. You will transition from manual API testing to writing powerful, automated test scripts using Java and REST Assured. By reading structured explanations and studying practical code examples, you will learn how to validate server responses, handle complex payloads, and integrate your tests into modern development workflows. What you'll learn: Understand foundational REST API concepts, HTTP methods, status codes, and headers; Configure REST Assured in a Java environment and write your first automated GET and POST requests; Validate API responses using built-in assertions, JSON path extractors, and matchers; Manage complex request payloads using serialization and deserialization with Jackson; Handle modern authentication mechanisms including Basic Auth, Bearer tokens, and OAuth flows; Structure your test suites cleanly using modern testing frameworks like JUnit 5. The course starts with the core concepts of APIs and HTTP protocols before guiding you through setting up your testing environment. You will then progress from basic requests to advanced assertions, payload management, and authentication handling, ensuring a complete grasp of automation best practices. This course is designed for manual testers, QA engineers, and developers who are new to API automation and want to learn REST Assured through clear, written instructions. No prior automation experience is required. Start reading today to build reliable API test suites and accelerate your quality assurance career.
