Take your REST API testing skills to the next level by learning how to design, automate, and maintain advanced API test frameworks using REST Assured, Cucumber, Java, and POJOs. This course is designed for software testers and automation engineers who want to build scalable, maintainable, and behavior-driven API testing solutions. You will begin by configuring a Maven-based REST Assured project and implementing complete CRUD API testing workflows, including authentication, request chaining, response validation, and reusable test structures. You will then integrate the Cucumber framework to create human-readable API test scenarios using Gherkin syntax and connect feature files with step definitions for behavior-driven development (BDD). The course also introduces data-driven testing by converting JSON payloads into Java POJOs, enabling structured request and response handling with object-oriented design. Throughout the course, you will apply reusable patterns that improve test organization, code reuse, and maintainability. By the end of this course, you will be able to configure advanced REST Assured projects, automate end-to-end REST API tests, implement BDD workflows with Cucumber, and build structured API test data using Java POJOs. If you want to create modular, scalable REST API automation solutions using modern Java testing practices, this course provides the practical skills to help you achieve that goal.

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.
