REST API testing mastery – Automation excellence with REST Assured

Modern applications run on APIs—and testing those APIs effectively is essential for delivering fast, reliable, and secure digital experiences. REST API Testing Mastery – Automation Excellence with REST Assured is a hands-on course built for developers, testers, and automation engineers who want to become fluent in testing RESTful web services using Java and the powerful REST Assured framework. From validating endpoints to building robust automated test suites, this course equips you with the skills and confidence to ensure API quality at scale. 💡 Why REST Assured? REST Assured is a Java-based library that simplifies testing of REST APIs with concise syntax, fluent assertions, and easy integration with test frameworks like TestNG and JUnit. It allows engineers to write readable, maintainable, and powerful tests for JSON and XML responses—making it the preferred choice for backend testing automation. 📘 What You’ll Learn Fundamentals of REST architecture and HTTP protocol Setting up REST Assured in a Java environment (Maven, IDEs, dependencies) Making GET, POST, PUT, DELETE requests and validating response codes Handling JSON and XML payloads in test scenarios Writing reusable request specs and response validations Using query parameters, path variables, headers, and cookies Building test frameworks with REST Assured + TestNG/JUnit Data-driven testing and dynamic payload generation Integrating with CI/CD pipelines and reporting tools 🧰 Tools and Libraries Explored REST Assured Java (basic to intermediate level) Maven for dependency management TestNG or JUnit for test orchestration Postman for test validation and manual inspection Allure or Extent Reports for reporting Jenkins (optional) for CI integration 🎯 Who Should Take This Course? QA engineers and test automation specialists working on web APIs Backend developers who want to validate services programmatically Technical professionals preparing for test engineering roles Anyone transitioning into API-first development and testing workflows Basic understanding of Java is recommended. If you're new to programming, we'll guide you through the essential syntax with step-by-step examples. 🔬 Real Projects & Practice Labs You’ll build: Automated tests for a sample REST API (CRUD operations) Data-driven scenarios to test different input conditions Test suites with custom validations and environment configs Test frameworks that can be triggered via command line or CI pipelines 📈 Outcomes & Career Impact By the end of this course, you’ll be able to: Write clean, reusable REST API test automation scripts Build scalable automation frameworks with REST Assured Integrate API testing into agile development and DevOps workflows Boost your resume with in-demand automation skills for testing and quality engineering
