API Testing with REST Assured: Java Automation Fundamentals

Software teams rely on robust APIs to power modern applications, making automated API testing a critical skill for developers and QA engineers alike. If you want to transition from manual API testing to automated Java-based test suites, mastering REST Assured is the most efficient way to achieve your goal. This course guides you from the fundamental concepts of HTTP and API structures to writing clean, automated tests. You will learn how to handle request and response specifications, parse JSON and XML data, and integrate modern Java features for cleaner payload management. What you'll learn: - Understand foundational API concepts, HTTP methods, and response status codes - Configure REST Assured in Java to send GET, POST, PUT, and DELETE requests - Validate API responses using Groovy GPath expressions for complex JSON and XML payloads - Apply modern Java features like Records and Jackson for seamless serialization and deserialization - Implement response specifications and base configurations to minimize test code duplication - Verify data integrity by performing schema validation against JSON and XML definitions The journey begins with essential terminology and setup before moving into hands-on test creation. You will progress from simple assertions to advanced payload handling and structured test maintenance. This course is designed for beginners to API testing and Java developers looking to expand their test automation skills, requiring only basic programming familiarity.
