REST Assured - Mastering API Testing

Overview

This comprehensive course empowers learners to understand, apply, and evaluate modern API testing methodologies using the RestAssured framework. Beginning with core API fundamentals and setup procedures, the course walks learners through configuring a robust Java-based test environment with Maven and Eclipse, and crafting basic REST API tests. As learners progress, they gain hands-on experience with constructing, executing, and validating various HTTP methods (GET, PUT, PATCH, DELETE) and analyzing JSON data structures through JSONPath and JSONObject. Key emphasis is placed on implementing security measures including authentication and authorization, as well as applying parameterization techniques for scalable, data-driven testing. In the final module, learners will develop and execute behavior-driven frameworks using Cucumber and feature files, then assess their test strategies via structured test execution and reporting. By the end of this course, participants will be able to design maintainable test suites, execute complete REST API workflows, and evaluate the effectiveness of their test coverage in real-world scenarios. This course is ideal for testers, automation engineers, and developers looking to elevate their API testing skills using structured frameworks and industry best practices.

Syllabus

API Fundamentals & Setup Essentials

This module introduces learners to the foundational concepts of APIs, web services, and the importance of API testing. It also guides the learner through setting up the development environment using Maven and Eclipse, and writing the first basic RestAssured test using JSON data structures.

Working with Requests and Responses

This module focuses on practical API request handling including PUT, PATCH, DELETE methods, and working with JSON structures using JSONPath and JSONObject. It also covers key concepts in API security—authentication, authorization—and techniques for parameterizing test inputs.

Automation Framework and Execution

This module walks learners through designing a behavior-driven automation framework using Cucumber, executing end-to-end API test scenarios, and reviewing the complete testing process in a structured workflow using RestAssured.
