A smarter way to learn with interactive, real-time conversations that help you test your knowledge, challenge assumptions, and deepen your understanding as you progress through the course. Master the essentials of REST API testing with REST Assured, the industry-standard Java library for validating HTTP responses. You’ll gain the confidence to build robust, scalable test automation frameworks and extract meaningful insights from API responses using modern tools and techniques. The course begins with prerequisite setup, introducing you to the essential tools and target APIs used throughout. You'll then build a REST Assured test framework from the ground up, configuring request and response specifications, and setting up endpoints. By mid-course, you’ll dive deep into executing various HTTP requests—GET, POST (JSON & XML), PUT, DELETE—while applying path and query parameters effectively. Next, you'll explore asserting and extracting data from responses, including headers and payloads. You’ll work with JSON Path and POJOs, validate schemas, and measure response times. The final modules cover Groovy GPath for advanced JSON and XML manipulation, helping you extract, filter, and analyze data efficiently. This course is perfect for testers, developers, and QA professionals aiming to boost their API automation skills. A basic understanding of Java and REST APIs is recommended.

In this module, we will introduce the course and set up the essential environment to get started with REST Assured. You'll learn about the software tools needed and get acquainted with two sample APIs—Video Game DB and Football Data API—that will be used for hands-on learning. This foundation ensures you're ready to dive into API testing with REST Assured.
