質問 5：
You work for a company who are pioneers in smart energy technology. One of their core products is their energy monitor in-home display device, used to display current and historic energy consumption data to many thousands of customers. It has been designed to integrate with their other smart-home products, including domestic lighting control systems via their HomeHub.
The company is to launch a new application for smartphones and tablets that will allow its customers to view their energy readings remotely and to view their daily budget usage based on seasonal historic data. The application must also support customers with disabilities.
The application is being delivered using a hybrid mix of agile and V-model methodologies over three iterations:
Iteration 1 - Development of the new application to work on the IOS operating system only.
Iteration 2 - Enhancement to the application to also work on the Android operating system.
Iteration 3 - Enhancement to the application to provide daily budget usage.
The test manager has provided you with a list of high-level test conditions and has asked you, as Test Analyst, to select the test conditions that address functional suitability, portability, usability and accessibility for Iteration 1 only.
Which TWO of the following test conditions should you select?
a. The application will accept voice recognition commands made via IOS devices.
b. The application is both learnable and operable for customers when used on Android devices.
c. There is no loss or corruption of data transmitted between the energy monitor and other smart- home products.
d. The daily budget usage is accurately calculated from seasonal historic data running on Android.
e. The application can be installed on all currently supported versions of IOS for all supported smartphones and tablets.
A. a, e.
B. a, b.
C. c, e.
D. b, d.
正解：A

質問 6：
Which task is NOT considered the responsibility of the Test Analyst as part of the test Implementation activities?
A. Creating automated tests or identifying tests to be automated.
B. Updating the traceability between the test basis and testware.
C. Creating a test execution schedule, including resource allocation.
D. Reporting defects based on the failures observed.
正解：A

質問 7：
Tax system
A tax system needs to be updated due to new legislation. For a person with a salary of less than
20.000 and who is married, the tax needs to be re-calculated. If the person also has more than two and less than five children, an additional 10% reduction is applicable.
Applying equivalence partitioning to the "Tax System" specification, which of the following set of equivalence classes is most effective in testing the processing the number of children?
A. 2, 4 and 6 children
B. 1, 3 and 6 children
C. 2, 4 and 5 children
D. 3, 4 and 6 children
正解：C

B. Usability laboratory
C. SUMI
D. Heuristic evaluation
E. Pairwise testing
F. Use case testing
G. Equivalence partitioning
正解：C,D,F

質問 9：
Which test technique is MOST closely associated with classification tree diagrams?
A. Use case testing.
B. Decision table testing.
