REST Assured API Testing with Java – Manual & Automation

Course Overview – Master API Testing & Automation with REST Assured and Java

API Testing is one of the most in‑demand skills in modern QA, Automation, and SDET roles. Most applications today are built using REST APIs and microservices, making API validation and automation a critical requirement.

This course is designed to take you from absolute beginner to job‑ready, even if you have no prior experience in API testing or automation. You will learn Manual API Testing using Postman and API Automation using REST Assured with Java in a structured, step‑by‑step manner, following real industry practices.

Why This Course Is Different

This course is built using real‑world industry scenarios rather than theory.

You will learn:

• How API testing is actually performed in real projects

• How automation frameworks are structured in companies

• How to apply each concept confidently on live applications

• How to prepare for API Automation and SDET interviews

Every topic is explained clearly, with practical examples, so you can apply what you learn immediately.

What You Will Learn

Manual API Testing

• Understanding APIs, REST architecture, and endpoints

• HTTP methods, headers, request and response structures

• Status codes and response validations

• Working with payloads and real test scenarios using Postman

API Automation Testing with REST Assured & Java

• Complete REST Assured setup from scratch

• Java fundamentals required for API automation

• Writing automated API tests step by step

• Validating JSON and XML responses

• Assertions, data handling, and reusable methods

• Test execution using TestNG and Maven

• Building and running automation tests like real projects
