API Testing with REST Assured and Java: A Practical Project

Testing APIs is a critical skill for modern software development and quality assurance, yet moving from manual testing to automated validation can feel daunting. This course bridges that gap by guiding you step-by-step through writing automated API tests using Java and REST Assured. By reading through our structured explanations and clear code examples, you will transition from understanding basic HTTP requests to constructing a fully automated test suite for a mock book store application. You will gain a practical grasp of how to validate responses, handle authentication tokens, and structure clean test code. What you'll learn: Understand the fundamental concepts of RESTful APIs, HTTP methods, and status codes; Configure a modern Java testing environment and integrate the REST Assured library; Send GET, POST, PUT, and DELETE requests to interact with a book store service; Validate API responses using JSON Schema assertion techniques to ensure data integrity; Handle secure authentication workflows, including user registration and token generation; Structure organized test classes to keep your automated testing codebase clean and maintainable. The course begins with foundational API concepts and environment setup before progressing to practical request building. You will then explore topics like token-based authorization and schema validation through clear, written walk-throughs and code snippets. This course is designed for beginners to API automation and those with basic Java familiarity; no prior experience with REST Assured or automated testing is required. Start reading today to build your automation skills and confidently test modern web APIs.
