Selenium couldn’t be used for Mobile Application Testing. It is built for automating web application testing. However, you could test mobile applications using Selenium-based frameworks like Appium or Selendroid. Selendroid is built for testing only Android applications, whereas Appium would be the tool if you go for cross-platform testing. Nowadays, Selendroid comes bundled within Appium. If you are someone who is interested in learning Selenium then I would recommend you to check out the Selenium training from Intellipaat. Also, have a look at our YouTube video on Selenium Course and check out the Selenium tutorial.
