API Test Automation with REST Assured, Java, and Cucumber

As modern software increasingly relies on interconnected web services, ensuring API reliability is a critical skill for quality assurance. Testing these interfaces manually is slow and error-prone, making automated testing essential for modern development pipelines. This written course guides you through creating robust, automated test suites for RESTful APIs. You will learn how to write clean, maintainable test scripts using Java and REST Assured, and how to structure your test suites using behavior-driven development (BDD) principles to foster collaboration across your entire team. What you'll learn: - Understand the fundamentals of REST APIs, HTTP methods, status codes, and JSON payloads. - Write structured API test assertions using REST Assured and modern JUnit 5 features. - Implement behavior-driven development (BDD) workflows using Cucumber and Gherkin syntax. - Map human-readable feature files to reusable step definitions in Java. - Manage complex request payloads efficiently using modern Java features like records and serialization libraries. - Validate JSON schemas to ensure API responses match strict data contracts. The course starts with foundational API concepts and REST Assured setup before progressing to test framework design. You will then explore advanced patterns, payload management, and BDD integration to build a production-ready testing suite. This course is designed for beginner automation engineers, manual testers, and software developers looking to transition into automated API testing. No prior experience with REST Assured or Cucumber is required, though a basic familiarity with Java is helpful. Start reading today to build reliable, industry-standard API testing frameworks.
