ISTQB ASTQB Practice Test - Questions Answers

An application that resides on the mobile device rather than on a web server and is written to work with a specific device is a native application.

This is an example of EP where all the members of the class are expected to behave in the same manner, therefore only one member of the class needs to be tested. Combinatorial technique is not the correct answer because that would be looking to reduce the set of test devices based on creating combinations to test.

Agile, a form of iterative lifecycle models, is often used for developing mobile applications as are other iterative lifecycles. Waterfall and V-model would be used for safety-critical where more documentation and control is required. The "mobile model" doesn't yet exist but may in the future!

Use cases should supply the expected usage scenarios. User stories are too brief to give the scenario view. Usability requirements generally focus on the user interface requirements rather than usage scenarios. Requirements specifications are notorious for not having much information regarding actual usage.

B is correct since this is a time challenged project. If there were adequate time, A might be the right answer, depending on the criticality of the product. C is never a good idea since even minimal risk analysis is needed to focus the testing. D is risky because the interaction of the application with the physical capabilities of the device still need to be tested.

Testing the physical device's interaction with the application is important. A is not correct because B is correct. C is not correct and a native application is developed for a specific device and is generally not portable. D is incorrect because devices have many, many features and testing all the features would be out of scope for the application under test.

D is correct as it tests each condition with invalid too low, valid and invalid too high values. A is incorrect because it doesn't consider the list save capabilities and it doesn't test the invalid values for the list. B is incorrect because it is doing BVA which results in too many tests for minimum coverage with EP. C is incorrect because it does not sufficiently test the save feature.

B is correct because it is doing BVA on both the list quantity and the list saving capability. D is incorrect because it has achieved EP coverage, but didn't get the boundaries. A is incorrect because it doesn't consider the list save capabilities and it doesn't test the invalid values for the list. C is incorrect because it does not sufficiently test the save feature.

A is correct per the syllabus. The others are quality characteristics, but are not components of correctness.
