[Solved] what is Selenium?

Selenium is a popular open-source tool for automating web browsers. It is primarily used for testing web applications to ensure they function correctly across different browsers and platforms. Selenium supports multiple programming languages, including Java, Python, and C#, making it highly versatile. It includes several components: Selenium WebDriver, which interacts with web browsers to perform user actions; Selenium Grid, which allows for parallel testing across various machines and browsers; and Selenium IDE, a browser plugin for recording and playing back tests. Selenium's flexibility and robust features make it a preferred choice for developers and testers worldwide.
