A fitness app displays a map during outdoor running. Testers report that the map is hard to read in bright sunlight and that the 'Start' button is difficult to tap while running. Which usability testing approach would best address these issues?

Conduct a lab-based usability test with a high-brightness display and a finger-sized stylus to simulate gloved hands.

Perform a field test with real users running outdoors, observing how they interact with the map and the start button under actual sunlight and motion.

Run an automated UI test that checks the contrast ratio of the map colors and the size of the start button.

Ask users to rate the app's usability in a survey after they have used it indoors for a week.

Which of the following is a focus of resource-related testing for a mobile app?

Testing the app's response to incoming notifications

Checking the app's compatibility with different OS versions

Verifying the app's user interface is intuitive

Monitoring the app's battery consumption

A video conferencing app must maintain call quality on low-bandwidth networks while also minimizing battery drain. The team has conflicting requirements: higher video resolution improves quality but increases battery and bandwidth usage. Which testing strategy would best help the team find an acceptable balance?

Run performance tests under various network conditions while measuring battery consumption and video quality metrics.

Focus on battery testing by running the app on a low-end device with the screen brightness at maximum.

Test the app's adaptive bitrate algorithm in a lab with simulated networks to see how it adjusts quality.

Test the app at maximum video resolution on a high-bandwidth network to ensure the best quality.

What does context-related testing for a mobile app verify?

The app's compatibility with different screen sizes

The app's behavior in various real-world contexts such as location and orientation

The app's performance under heavy network load

The app's security against unauthorized access

A retail app's checkout page uses a fixed-width layout that works on a 6.5-inch phone but clips buttons on a 5.0-inch device. The team wants to ensure the layout adapts correctly across the range of devices they support. Which testing approach is most appropriate?

Run a performance test on a low-end device to see if the checkout page loads quickly.

Test the app on the smallest and largest supported devices, and on a mid-range device, to verify the layout adapts without clipping.

Ask developers to review the layout code to ensure it uses responsive design principles.

Use an emulator with a single screen size that matches the most popular device model.
