Appium supports cross-platform testing by using a single API that works across both Android and iOS, eliminating the need for separate test scripts. It achieves this through the WebDriver protocol, using UIAutomator2 for Android and XCUITest for iOS. This allows testers to write one set of tests that can run on different devices with minimal code changes. In New York, USA, where mobile development is highly dynamic, cross-platform capability reduces maintenance costs and accelerates release cycles. Appium’s flexibility ensures developers can test native, hybrid, and mobile web applications efficiently, making it a top choice for automation teams.
