REST Assured Java API Testing Automation

Overview

This course is designed for software testers and automation engineers seeking to analyze, construct, and implement advanced REST API testing solutions using Java. Divided into two comprehensive modules, the course first explores behavior-driven development (BDD) through integration of the Cucumber framework with REST Assured. Learners will gain hands-on experience writing human-readable test cases using Gherkin syntax, setting up reusable background steps, and bridging feature files with step definitions. The second module transitions into data-driven testing, focusing on transforming JSON payloads into Plain Old Java Objects (POJOs). Learners will develop structured test flows using object-oriented techniques, enabling dynamic handling of API request and response bodies. Emphasis is placed on real-world application, code reuse, and scalable test automation design patterns. By the end of the course, participants will be able to confidently construct, execute, and validate complex REST API test cases in a maintainable and modular fashion using modern Java testing frameworks.

Syllabus

Advanced Test Automation with REST Assured

This module delves into advanced concepts of REST Assured Java by guiding learners through practical configurations, project structuring with Maven, and comprehensive end-to-end API testing workflows. It begins with foundational setup practices, including project metadata management and POM configuration. Learners are then introduced to real-world CRUD operations in REST APIs and are taught to implement robust testing strategies using authentication, request chaining, and response validations. The module culminates in dynamic handling of test data and the use of scalable patterns for automating interactions with RESTful services.

Behavior-Driven and Data-Driven API Testing

This module introduces learners to the integration of the Cucumber framework with REST Assured for behavior-driven API testing and extends into data-driven automation through JSON to Java POJO conversion. The first half focuses on writing human-readable test scenarios using Cucumber's Gherkin syntax, implementing background setups, and structuring feature files for end-to-end API testing. The second half transitions into converting JSON payloads into Plain Old Java Objects (POJOs), enabling structured and type-safe test data management and response validation. By the end of this module, learners will have the skills to implement both BDD-driven tests and advanced data mapping techniques in REST Assured.
