A shopping app registers a custom URL scheme for product pages (e.g., `shopapp://product/123`). A tester sends a URL with an invalid product ID. The app shows an error message but then crashes when the user taps 'OK' on the error dialog. The app also does not handle URLs from unknown apps. What is the most critical issue to address?

The app does not validate the product ID in the URL

The app does not show a specific error message for invalid product IDs

The app crashes when the user taps 'OK' on the error dialog

The app does not handle URLs from unknown apps

A fitness app uses the device's step counter sensor. While the app is in the background, another app also starts using the step counter. When the user returns to the fitness app, the step count is incorrect. What should the tester verify?

That the app requests permission to access the step counter

That the app correctly handles sensor data conflicts when another app is using the same sensor

That the app handles the system notification bar correctly

That the app maintains its state when returning from the background

A social media app registers a custom URL scheme so other apps can open a specific user profile. During testing, the tester sends a URL with an invalid user ID to the app. The app crashes instead of showing an error message. What should the tester verify to ensure the app handles this scenario correctly?

That the app requests permission before opening the URL from another app

That the app validates the URL scheme and only accepts requests from trusted apps

That the app gracefully handles malformed URLs and shows a fallback screen or error message

That the app opens the URL in a web view instead of natively

Which scenario is an example of app-to-app interaction testing?

Tapping a button in the app that opens the device's camera app to take a photo.

Checking that the app's push notifications appear when the device is locked.

Verifying that the app's splash screen displays for the correct duration.

Rotating the device to verify the app's layout adjusts correctly.

A payment app allows users to pay via a third-party wallet app. The tester initiates a payment, which launches the wallet app. After the payment is completed, the wallet app returns to the payment app. The payment app shows a 'Payment Successful' message, but the transaction is not recorded in the payment app's history. The tester also notices that if the wallet app is not installed, the payment app crashes. What is the most critical issue to address?

The payment app does not maintain its state when returning from the background

The payment app does not record the transaction after the wallet app returns

The payment app does not handle the return from the wallet app correctly

The payment app crashes when the wallet app is not installed
