Selenium is primarily used for automating web browsers on desktop platforms. It allows developers and testers to write scripts in various programming languages (e.g., Java, Python, C#, etc.) to interact with web applications and perform automated testing.

At that time, Selenium was not specifically designed for mobile browsers. However, there were ways to perform mobile browser testing using Selenium by integrating it with third-party tools or frameworks, such as Appium.

Appium is an open-source tool that extends the capabilities of Selenium to automate mobile applications, including mobile web browsers. It supports various mobile platforms like Android and iOS and provides a web driver interface, allowing developers to use Selenium-like commands for mobile browser automation.

To use Selenium with mobile browsers, you would typically set up the Appium server, connect your mobile device or emulator to it, and then use the Appium WebDriver in your test scripts. Appium translates the Selenium commands into corresponding actions on the mobile device’s browser.

Since the software landscape is continually evolving, it is possible that there have been updates or new tools specifically designed for mobile browser testing using Selenium. For the latest information, I recommend checking the official Selenium and Appium documentation or looking for updates in the testing community.
