Which of the following the tester must understand while selecting the test tool?
Which of the following is a reason to use simulators for testing?
B is correct. A is incorrect because real devices will always be more accurate. C is incorrect because usability requires the look and feel of the real device. D is not true on a large scale and may not even be true on a small scale. A well-designed simulator should be easier to re-configure as needed.
You are planning to conduct performance testing on a new application. You have been given a set of personas to use during this testing.
How should you apply the personas in the performance testing approach?
A is correct. Personas represent realistic users doing realistic transactions and so are well suited for use in performance testing. B is not correct because transactions are needed for performance testing rather than tasks. C is not correct because while personas are used for usability testing, they are also used for performance testing. D is not correct because user stories cover small bits of functionality, not transactions.
You have just been assigned to test a native mobile application for a delivery recording device used by mail and package couriers. This is a new version of a product that is already in production. The production version of the product has had issues with the hardware particularly with capturing signatures entered on the device and with associating photo images to the proper delivery addresses. This has resulted in a problem with reconciling the package delivery information. You need to test the application on a network with 1000 of these devices sending information back to the main office. Budget is limited as is the ability to obtain 1000 devices.
What should you do?
Given this scenario, B is the correct answer. An emulator will allow testing to be conducted to verify the interaction between the hardware/OS and the application and that's where the main problems have been. A is not correct because a simulator will not be able to simulate the interaction between the application and the hardware and that is identified as a key issue with the current production product. C is not correct because this is not a device that most people would have access to -- it's a business device rather than a personal device. D is not correct because a good emulator should be able to provide the needed test environment. And, the question states that budget is limited and devices are hard to get.
