The purpose of Selenium is to test web applications by simulating user interactions. Selenium is a powerful tool primarily used for automating tests in web applications. It allows testers to write scripts in various programming languages to interact with the web elements, such as buttons, forms, and links, just as a user would. This capability enables the testing of user scenarios and ensures that the web application behaves as expected under various conditions.

By automating these interactions, Selenium helps identify bugs, verify functionalities, and ensure user experience quality, making it an essential tool for quality assurance in web development. Testing through Selenium is integral to the software development lifecycle, supporting continuous integration and delivery practices by providing quick feedback on code changes.

In contrast, other options like developing web applications, building backend servers, or creating content management systems do not align with Selenium’s capabilities, as these activities pertain to software development rather than testing.
