I tried to set up Xamarin UI test for my app in real device. I have .ipa only, but no source code. When I star the app, the error as following. Any help is appreciated!
SetUp : System.Exception : Unable to contact test backend running in app. A common cause is that the app is not properly linked with Calabash. Please verify that it includes the Calabash component.
