BCS TA12 問題集

質問 1：
For an ATM banking project introduced earlier, "When the user first inserts a valid credit card type, the system considers the user to be in an unauthenticated state. When requesting a cash advance, the user must be in an authenticated state. The user authenticates by entering the proper PIN code. When authenticating the user, the system shall allow the user to enter their PIN code up to three times before failing the authentication and rejecting the card. On the first and second try, the system shall prompt the user to re-enter the PIN code."
Suppose you are concerned that, depending on the exact number of invalid PIN codes entered, the system might behave improperly. Which of the following test design techniques is specifically targeted at such failures?
[K4] 3 credits
A. Pairwise Testing with orthogonal arrays
B. Classification Tree Method
C. Equivalence Partitioning extended by boundary value analysis
D. State Transition Testing using 1-switch coverage
正解：D

質問 2：
A new banking system has 2 customers' types, 2 account types and will operate in two different countries?
How many test cases will be needed using the pair wise testing technique and the appropriate 2-wise orthogonal array?

質問 4：
While identifying scenario's for the use case "copy A4 - A4" for a new copier, the following scenario's were identified:
Basic scenario: single side to single side
Deviations: single side to double side, copy of a set, copy using the automatic document feeder
Failures: no paper in paper tray, paper jam, out of staples

正解：B

質問 5：
Tax system
A tax system needs to be updated due to new legislation. For a person with a salary of less than EUR 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?
[K3] 2 credits
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

質問 6：
A company offering house insurance policies has several policy options. They depend on
the following factors:
-Building type: house, semi-detached, apartment building, cottage Material: wood, concrete, brick, mixed Location: city, suburb, countryside, wilderness
It has been decided to use the pair wise test technique and apply 2-wise coverage. To design the test case an appropriate orthogonal array needs to be located.
Which of the following orthogonal arrays is to be selected for testing the house insurance policies?
[K3] 3 credits
