Build practical API testing skills with RestAssured by learning how to design, execute, and validate API tests in a structured workflow. This course introduces the fundamentals of APIs and web services before guiding you through setting up a Maven-based Java project, creating your first RestAssured test, and working with JSON data. As you progress, you'll construct API requests using HTTP methods such as GET, PUT, PATCH, and DELETE, manipulate JSON with JSONPath and JSONObject, and apply authentication, authorization, and parameterization techniques to strengthen your API test cases. You'll then design and execute a behavior-driven development (BDD) automation framework using Cucumber and complete end-to-end API testing scenarios with RestAssured. Designed for learners who want to develop practical API testing skills using Java and RestAssured, this course follows a step-by-step approach from foundational concepts to automation framework design and execution. Each module builds on the previous one, helping you understand the complete API testing lifecycle while reinforcing industry-relevant testing practices. By the end of the course, you'll be able to configure a RestAssured project, create and validate API requests and responses, implement authentication and parameterization techniques, and execute API test automation using a structured BDD framework with Cucumber.

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.
