A team releases a mobile app every two weeks. They have a test environment that mirrors production, but the backend API sometimes has breaking changes. The team wants to ensure that the app works with the latest backend before each release. Which approach best balances testing time and coverage?

Use a mock backend for all testing to avoid dependency on the real API.

Wait until the backend is stable and then run a full regression test manually.

Run automated integration tests against the staging backend as part of the CI pipeline.

Test the app only against the production backend to ensure real-world compatibility.

A team is testing a photo editing app that is known to be memory-intensive. The app crashes on a device with 2 GB RAM when the user edits a large photo. The team wants to fix this issue before the next release. What is the most effective testing approach to identify the cause?

Test the app on a device with 4 GB RAM to see if the crash occurs there.

Use a memory profiling tool to monitor memory usage while reproducing the crash.

Reduce the size of the test photo to avoid the crash.

Ask the developer to review the code for memory leaks.

Which of the following is an example of a context-aware interruption that a mobile app must handle?

The user adjusting the screen timeout setting

The device battery level dropping to a critical level

The user connecting a Bluetooth headset

The user changing the device's wallpaper
