API Test Automation: REST Assured, Java, and Postman from Scratch

Modern software architectures rely heavily on APIs to connect services and deliver seamless user experiences. Ensuring these APIs are reliable, fast, and secure requires robust automated testing. This written course takes you from API testing fundamentals to designing and implementing a scalable automation framework. You will transition from manual API exploration to writing clean, maintainable automated test suites that integrate easily into modern development workflows. What you'll learn: - Understand core API concepts, HTTP methods, status codes, and manual testing using Postman - Write automated API tests using REST Assured, Java, and the TestNG testing framework - Build a production-ready test automation framework from scratch with clean code practices - Handle complex payloads, dynamic data, and modern authentication flows like OAuth 2.0 - Validate API responses using JSON schema validation and assertions for robust test coverage - Configure automated test suites to generate clear reports and prepare them for CI/CD integration The course begins with foundational API concepts and manual testing techniques before introducing Java programming basics for automation. You will then progressively build a fully functional automation framework, learning how to handle real-world API scenarios step by step. This course is designed for quality assurance engineers, manual testers, and software developers looking to transition into API automation. No prior coding or test automation experience is required.
