Selenium WebDriver
Selenium WebDriver is an open-source automation framework for web applications that provides a programming interface to control web browsers like Chrome, Firefox, and Safari. It allows developers to write scripts in various programming languages (e.g., Java, Python, C#) to simulate user interactions such as clicking buttons, filling forms, and navigating pages. It is widely used for automated testing of web applications, enabling cross-browser and cross-platform validation.
Developers should learn Selenium WebDriver when they need to automate repetitive web testing tasks, ensure consistent functionality across different browsers, or integrate testing into CI/CD pipelines. It is essential for roles involving quality assurance, test automation, or web development where reliable, scalable testing is required to catch regressions and improve software quality.
