ISTQB - Mobile Application Testing 05

Handling of interrupts, notifications and optimizations, is considered as a test condition for testing:

• Interoperability with multiple platforms and operating system versions
• Interoperability and co-existence with other apps on the device
• The app notifications
• Access permissions to device features

Answer explanation

The test condition must be considered for testing the interoperability with multiple platforms and operating system versions is: Handling of interrupts, notifications and optimizations.

Which of the following tests you should consider when testing the interoperability of a mobile application and it's co-existence with other apps on the device?

• Check if the application can send notifications when other apps are running
• Check the application's handling of notifications received from other apps
• Check if the application has any conflicting behavior with the other apps
• Check if the application causes the device to be overheated when running in the background of other apps

Answer explanation

c) is correct. As per the syllabus p. 25, Under the " Testing for Interoperability and Co -existence with other Apps on the Device" headline, the syllabus states that: "The following test conditions must be considered:

● Data transfer between the system under test and the utilized app is correct.

● There is no harm done to any user data stored within a utilized app.

● Conflicting behaviors. For example, an app might turn off GPS to save energy, while another app turns on GPS automatically."

Which of the following tests is LEAST related to multiple platforms interoperability testing?

• Testing for backward compatibility
• Testing new features of platforms
• Testing for notifications handling
• Testing for user preferences

Which of the following mobile application types need MORE concern about performance issues?

• Native applications
• Hybrid applications
• Web applications
• Browser-bases applications

Answer explanation

b) is correct. As per the syllabus p. 24, " The following test conditions must be considered:

● For hybrid apps: o Interaction of the app with the device native features

● Potential performance issues due to the abstraction layer

● Usability (look and feel) compared to native apps on the platform in question "

You are designing the test scenarios of a sticky notes android mobile application, which of the following scenarios will be included in the quick access links test suite?

• The app can add, edit & remove sticky notes correctly
• The notes added from the home screen shortcut can be viewed inside the app
• Updating the app does not delete the created notes
• The app is easily accessible by people with special needs

Answer explanation

b) is correct. As per the syllabus p. 24, Under the "Testing for Quick -access Links" headline, the syllabus states that: "The following test conditions must be considered: • The actions performed in quick -access links are reflected correctly in the app when opened. "

You are testing a courses provider mobile application. When there are new offers on courses, the application sends notifications to the interested users. What is the MOST important test condition you have to verify for this feature?

• Verify that the app sends notifications to all users for all courses to ensure that a large number of students will enroll in the offered courses
• Verify that the courses offers are attractive enough for users to enroll.
• Verify that the app opens the offered course's page when the user taps on the notification
• Verify that the user receives the notification even when he is enabling the "do-not-disturb" mode.

Answer explanation

c) is correct. As per the syllabus p. 24 "If notifications allow access to the app then the corresponding page of the app must be opened instead of the home screen when the notification contains a deep link to that page . "

A logo maker mobile application works well when using its graphical objects, but when trying to open a photo from the gallery, the app suddenly freezes and don't respond. In your opinion which type of tests may be neglected by the app's testing team?

• Testing for device input sensors
• Testing for various input methods
• Testing for access permissions
• Testing for quick access links

Answer explanation

c) is correct. Since the problem appears when the trying to open a photo from the device gallery, so it is an "Access Permission" problem.

After releasing the Beta version of your company's new mobile application, a lot complaints are received stating that the app suddenly stops when connecting/disconnecting the charger. Which of the following tests may not be applied thoroughly?

• Testing for Device Input Sensors
• Testing for Power Consumption and State
• Testing for Device Features
• Testing for Typical Interrupts

Answer explanation

d) is correct. As per the syllabus p. 22, Under "Testing for Typical Interrupts" heading, the syllabus states that "Common types of device interrupts include voice calls, messages, charger switched on, low memory and other notifications. "

Which of the following is a test condition for a video streaming mobile application regarding changing the screen orientation?

• Check that the network signal strength is not affected by changing the screen orientation
• Check that the videos running in landscape mode continue playing under low battery condition
• Check that receiving the app notifications does not change the screen orientation
• Check that the video is not reloaded when changing the orientation

Answer explanation

d) is correct. Maintaining the application's state is one of the test conditions for screen orientation changing. As per the syllabus p. 22, "Tests after a change of screen orientation check the following:

● Correct usability and functional behavior when a switch to either portrait or landscape mode is performed.

● The app maintains its state.

● Input data fields retain already captured data.

● Output data fields display the same data while maintaining the current session. "

You are testing a photo gallery mobile application for various input methods, which of the following tests is OUT of your scope?

• Receiving a phone call does not close the opened photo
• Long press on any photo to select it
• Pinch open/close to zoom the photo in/out
• When a photo is opened, swipe left & right to navigate between photos

Answer explanation

a) is correct. Because it is one of the test conditions of "Testing for Typical Interrupts", as per the syllabus p. 23, "Test should be designed for receiving interrupts during app usage to make sure that the interrupts do not have a negative impact. For example, answering a phone call while using the app and the user being returned to the state where he was at the time of the interrupt."
