REST API Automation with REST Assured Practice Exam
About REST API Automation with REST Assured Exam
REST Assured is a powerful tool for automating RESTful APIs and web services, similar to how Selenium WebDriver is used for web automation. Since most modern web applications rely on REST APIs to communicate with their backends, testing these APIs is a crucial step in ensuring software reliability. Automating API tests improves efficiency by making them faster, more stable, and easier to maintain compared to web UI tests. This course provides hands-on training in REST API automation, starting from basic API concepts and progressing to advanced testing techniques using REST Assured.
