What is Selenium WebDriver used for in real projects?

Selenium WebDriver is widely used in real projects to automate browser actions for web application testing. It interacts directly with browsers, simulating user activities like clicking, form submissions, and navigation. In Selenium testing, WebDriver supports multiple browsers such as Chrome, Firefox, and Edge, making it ideal for cross-browser testing. Teams use it to validate functionality, UI behavior, and performance under various conditions. It integrates seamlessly with frameworks like TestNG and JUnit and fits easily into CI/CD pipelines. This helps developers and QA professionals deliver high-quality, bug-free applications faster by ensuring consistent, automated test coverage throughout development cycles.
