Run your Appium tests in parallel on real devices with TestMu AI:- https://www.testmuai.com/real-device-cloud/?utm_source=youtube&utm_medium=organic&utm_term=WERyvCPLY9M&utm_campaign=Appium_4_shorts Planning to upgrade to Appium 4? Check these first: 1️⃣ Node.js 22.22 or above is required. Still on Node 20? Upgrade first. 2️⃣ Appium packages now use ES modules. If your scripts load Appium packages with require(), switch to import. 3️⃣ The legacy JSON Wire Protocol is removed. Older clients and automation backends may need updates. 4️⃣ Windows automation has changed. The WinAppDriver-based Windows Driver is replaced by WinCore, which works directly with the Windows UI Automation API. 5️⃣ XCUITest and UiAutomator2 have Appium 4 beta versions. Check driver compatibility before upgrading. Appium 4 is still in beta, so test your setup in a separate environment first and read the official Appium 4 migration guide. Once you're ready, run your Appium tests in parallel across real Android and iOS devices and OS versions on TestMu AI Real Device Cloud. You get more coverage and faster runs, without maintaining your own device lab.
