Selenium

Selenium is an open-source automated testing tool widely used by software developers, quality assurance (QA) engineers, and testers to automate web browsers' actions. It provides a suite of tools that allow users to automate web-based applications' functional and regression testing across multiple browsers and platforms. Selenium supports various programming languages, including Java, Python, C#, Ruby, and JavaScript, and can be used with a range of browser automation frameworks, such as WebDriver, Selenium Grid, and Selenium IDE. With these tools, users can simulate user interactions with a web application, such as clicking links, filling out forms, and navigating between pages, and verify the application's behavior and functionality. One of the main benefits of Selenium is its ability to test web applications across multiple browsers, operating systems, and devices, which can save time and effort compared to manual testing. Additionally, Selenium supports various testing frameworks, such as TestNG and JUnit, and integrates with popular software development tools like Jenkins and Maven, making it a flexible and powerful tool for automated testing. Selenium is widely used in the software development industry, particularly for web-based applications. Its popularity and flexibility have also led to the development of various extensions and third-party tools, such as Selenium IDE, which allows users to record and replay interactions with web applications.
