We have an iOS 8 app on an iPhone 5S where our automated test script can perform 3 taps, and then the app hangs. If we test manually, the app behaves normally. The app hangs only when we use automated testing. When the app hangs, any taps (manual and automated) do not cause any response from the app or device. Pressing the home key returns us to the home screen, but this then leaves us unable to launch any other application. I tried looking into the issue by creating a quick test script using the Instruments Automation GUI, and I ran into the same issue: 3 taps and then a freeze.
If I terminate Appium or Instruments, the app is closed on the device, and the device's behavior returns to normal (responds to taps, able to launch apps from home screen).
I am hoping someone has encountered this same issue and would like to offer some advice. Help is gladly appreciated.
