While Appium offers flexibility, testers often face challenges like device compatibility, flaky tests, and slow execution speed. Managing dependencies between different OS versions and drivers (UIAutomator2 or XCUITest) can be complex. Testers also encounter synchronization issues, especially with dynamic elements. In New York’s high-paced tech environment, maintaining test stability across multiple devices and emulators is crucial. Using robust locators, explicit waits, and running tests on real devices via cloud services helps mitigate these challenges. Continuous monitoring, framework optimization, and adopting parallel testing can significantly improve test efficiency and reliability in Appium-driven projects.
