This intermediate-level course enables learners to apply, analyze, and evaluate RESTful API testing techniques using the REST Assured framework in Java. Through structured lessons and real-world examples, learners will build upon foundational REST concepts to construct and execute automated test scenarios for key HTTP methods including GET, POST, PUT, DELETE, and PATCH.

The course guides learners in implementing full CRUD operations with a hands-on approach, while introducing vital data handling concepts like serialization and deserialization for smooth API integration. Learners will also implement security mechanisms using authorization headers and Bearer tokens to interact with protected endpoints effectively. By the end of this course, participants will have the skills to create maintainable, scalable, and secure automated REST API tests, aligned with industry best practices.

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.

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.
