2. Selenium IDE (Integrated Development Environment): It is a browser extension that allows record and playback of user interactions with the web application. While it’s a handy tool for quick test script creation, it’s less suitable for complex testing scenarios.
3. Selenium Grid: Selenium Grid is used for parallel test execution. It enables tests to be distributed across multiple machines and browsers simultaneously, reducing test execution time.
4. Support for Multiple Programming Languages: Selenium supports various programming languages, including Java, Python, C#, Ruby, and others, making it flexible for developers to choose their preferred language.
5. Cross-Browser Compatibility: Selenium supports multiple web browsers, including Google Chrome, Mozilla Firefox, Microsoft Edge, Safari, and more. It allows for testing web applications across different browsers.
6. Operating System Independence: Selenium is platform-independent, which means you can run your tests on various operating systems, such as Windows, macOS, and Linux.
7. Extensive Community Support: Selenium has a large and active user community, offering a wealth of resources, documentation, and forums for support.
8. Integration with Testing Frameworks: Selenium can be integrate with various testing frameworks like TestNG, JUnit, and others, making it easier to manage test cases and execute tests.
9. Headless Browser Testing: Selenium supports headless browser testing, which allows tests to run in the background without a graphical user interface. It is useful for running tests on servers or in automated pipelines.

Selenium is widely use in software testing for web applications. It helps automate repetitive and time-consuming tasks, performs regression testing, ensures application functionality, and identifies defects early in the development process. Selenium’s flexibility and adaptability to various testing scenarios have made it a popular choice for quality assurance aned test automation in the software industry.

The adoption rate of automation testing is now 70%.[1]
