Appium

Appium is an open-source framework for automating native, mobile web, and hybrid applications on iOS, mobile Android, and Windows desktop platforms. It uses the WebDriver protocol.

When to Use

• Real Device Testing: Testing on physical iPhones/Androids.
• Cross-Platform: Write one test (mostly) for both iOS and Android.
• Black-box Testing: Testing the app from the outside (like a user) without needing source code access.
