Changes to Coded UI Test in Visual Studio 2019
We've been recommending for a while that customers use the open source tools Selenium and Appium tools, therefore the Visual Studio 2019 release marks their final deprecation.
We recommend using Selenium for testing web-applications and Appium with WinAppDriver for testing desktop (WPF, WinForms, Win32) and UWP apps. For testing Dynamics 365 apps, we recommend using the EasyRepro framework that is built on top of Selenium.
