Selenium
Selenium is an open source web browser automation software, mainly used for testing web applications. This allows testers and developers to create automated tests that reproduce typical user interactions in the browser.

Functionality and Use
The software allows you to automatically check web applications by simulating user actions in the browser. This includes, for example, clicking on elements, filling out forms or navigating between individual pages. The tests can be written in different programming languages and run in different browsers.
Selenium consists of several components, including Selenium WebDriver, -Grid and -Ide. These tools allow browsers to automatically control, distribute tests, and create test scripts. The scripts send commands to the browser, which executes actions, similar to a real user.
Examples
- Automating a login form
- Testing a shopping cart process in the browser
- Automatically fill out a form
- Testing a website in multiple browsers
