Mastering API Testing with Rest Assured

Mastering API Testing with Rest Assured-Live Training

(A Complete Hands-On Course on REST API Automation with Java, TestNG, and CI/CD Integration)

This course is a complete, hands-on journey into API testing and automation using Java, Rest Assured, and TestNG. Designed for both beginners and professionals, it starts with the fundamentals of APIs, HTTP methods, and REST vs SOAP, then guides you through setting up your environment, writing basic to advanced requests, and handling real-world challenges like authentication, serialization, and data-driven testing. You’ll also learn to build a reusable test automation framework, integrate it with CI/CD tools like Jenkins, and report test results using industry-standard tools like Allure or Extent Reports. The course wraps up with a real-world API testing project to apply everything you’ve learned in a practical setting.

About the Instructor:

Vijay is a Certified API Automation and Testing Professional with over 7+ years of real-world experience in API testing, framework development, and CI/CD implementation. Having worked across live production, sandbox, and enterprise-level environments, the instructor brings deep hands-on knowledge of RESTful services, test automation, and continuous integration. Their expertise spans key areas such as writing and validating HTTP requests (GET, POST, PUT, DELETE), data-driven testing, and creating reusable frameworks using Java, Rest Assured, TestNG, Maven, and more.

Specializing in automating API workflows, handling various authentication methods (OAuth 2.0, Basic, Bearer Tokens), and integrating with tools like WireMock, Jenkins, and GitHub, the instructor equips learners with the skills to test modern APIs efficiently. With strong command over JSON/XML parsing, response validation, and reporting with Allure, students benefit from a highly practical and project-driven learning experience that mirrors real-world QA environments.

Having successfully trained over 150+ students, the instructor is passionate about delivering an interactive, hands-on learning journey rooted in industry practices. The course emphasizes live testing scenarios, framework design, and real-time debugging strategies. By the end of the training, learners are fully prepared to take on professional roles in API testing and automation, confidently applying their skills in real-world software development and DevOps pipelines.
