COURSE DESCRIPTION

API Testing with REST Assured – Hands-On & Real-Time

This course provides a complete, hands-on journey into API Testing using REST Assured, combining strong fundamentals with real-world automation practices. It is designed to help learners move from basic API concepts to advanced API automation frameworks, giving them the practical skills required to test APIs confidently in real projects.

You’ll start by understanding API fundamentals, including REST architecture, HTTP methods, status codes, headers, and request–response structures. You’ll then learn how to set up REST Assured with Java, Maven, and TestNG, and begin writing your first automated API tests.

As the course progresses, you’ll dive deeper into hands-on automation, learning how to validate response bodies, headers, status codes, and performance. You’ll work extensively with JSON and XML, using JsonPath and XmlPath to extract and validate data.

You’ll also explore advanced API testing concepts, including authentication mechanisms (Basic, Bearer Token, OAuth), data-driven testing, request chaining, schema validation, and handling dynamic responses.

The course includes real-time examples, live project scenarios, and practical exercises, helping you understand how API testing is performed in real-world software development environments. You’ll also learn how to

• Design and automate API test cases using REST Assured

• Validate complex API responses effectively

• Handle authentication and authorization in APIs

• Build reusable and maintainable API automation frameworks

• Integrate REST Assured tests with TestNG and CI/CD pipelines

• Generate reports and analyze API test results

By the end of this course, you’ll have a strong foundation in API testing and REST Assured automation, along with the confidence to work on real-time projects, collaborate with teams, and crack API testing interviews.

Whether you’re a manual tester transitioning to automation, an automation tester enhancing API skills, a developer validating backend services, or a beginner starting your API testing journey, this course will give you practical, job-ready experience with one of the most in-demand skills in modern software testing.
