Testing Mobile Apps with Appium

One of the major differences introduced in Selenium 3 was the introduction of the Appium project. The mobile-testing features that were part of Selenium 2 are now moved into a separate project named Appium. 

Appium is an open source mobile-automation framework for testing native, hybrid, and web mobile apps on iOS and Android platforms using the JSON-Wire protocol with Selenium WebDriver. Appium replaces the iPhoneDriver and AndroidDriver APIs in Selenium 2 that were used to test mobile web applications.

Appium enables the use and extension of the existing Selenium WebDriver framework to build mobile tests. As it uses Selenium WebDriver to drive the tests, we can use any programming language to create tests for a Selenium client library.
