Interruption testing focuses on how a mobile application behaves during interruptions such as incoming calls, text messages, low battery warnings, network loss, etc. It’s essential to ensure that an application can handle such interruptions gracefully without crashing or losing critical data. Common use cases for interruption testing include:

 

Incoming Call: How the app behaves when there is an incoming call. For instance, does the app pause correctly, and can it resume without any issues once the call is finished?
Incoming Messages or SMS: Similar to incoming calls, how does the app manage itself when a text message arrives?
Low Battery: The app’s behavior during low battery conditions needs to be tested. Does it give proper notifications? Does it save the state so that no data is lost?
Plugging in/out of Charging: Understanding the app’s behavior when the device is plugged in or out of charging is important.
Device Shutdown: What happens if the device shuts down while the app is running? Can the app recover gracefully?
OS Upgrade: How the app behaves when there’s an OS upgrade happening in the background.
Loss and Restoration of Network: How the app handles network connectivity issues, for example, transitioning from Wi-Fi to mobile data, loss of connectivity, etc.
