Question
When we develop a mobile app, is it important to add interruption testing as another test strategy to ensure that the app behaves correctly under different interruption conditions ( incoming calls, SMS etc.). If yes, how often it should be incorporated into app's release cycle?
Answer
Personally I have never seen anyone do this nor do I think it is particularly necessary. You do want to make sure you check what your app does in a paused state (incoming call, app switching, rotation) if you need to save data or are showing sensitive user data.
