5.1What Appium Is and Why It Dominates

Appium is the most widely deployed cross-platform mobile testing framework. It automates native, hybrid, and mobile web applications on iOS and Android using the W3C WebDriver protocol. The key advantage: you write tests in any language (Python, Java, JavaScript, C#, Ruby) and run them against real devices or emulators without modifying your application.

Appium was created by Dan Cuellar in 2011 and has evolved significantly toward AI-native testing patterns in its 3.x releases.
