REST Assured - Mastering API Testing

Build practical API testing skills with RestAssured by learning how to design, execute, and validate API tests in a structured workflow. This course introduces the fundamentals of APIs and web services before guiding you through setting up a Maven-based Java project, creating your first RestAssured test, and working with JSON data. As you progress, you'll construct API requests using HTTP methods such as GET, PUT, PATCH, and DELETE, manipulate JSON with JSONPath and JSONObject, and apply authentication, authorization, and parameterization techniques to strengthen your API test cases. You'll then design and execute a behavior-driven development (BDD) automation framework using Cucumber and complete end-to-end API testing scenarios with RestAssured. Designed for learners who want to develop practical API testing skills using Java and RestAssured, this course follows a step-by-step approach from foundational concepts to automation framework design and execution. Each module builds on the previous one, helping you understand the complete API testing lifecycle while reinforcing industry-relevant testing practices. By the end of the course, you'll be able to configure a RestAssured project, create and validate API requests and responses, implement authentication and parameterization techniques, and execute API test automation using a structured BDD framework with Cucumber.
