A. During system test.
B. During component test.
C. During UAT using a WAMMI survey.
D. During beta acceptance testing.
正解：C

質問 3：
Which of the following statements BEST describes checklist based and black-box test techniques?
A. Checklists are an excellent source of test design for inexperienced testers, requirement specifications are often used as the basis for applying black-box techniques.
B. The checklist based technique is most effective when applied by experienced testers; black-box techniques are most effective applied against a well specified test basis.
C. Checklist based testing derives tests from lists which focus on defects; black-box techniques find defects through systematic test case design.
D. The checklist based technique produces consistent, reproducible test cases; test cases produced by black-box techniques are less systematic.
正解：C

質問 4：
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?
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 5：
A web-based system is being developed to support the administration of tennis tournaments.
The system provides advice on how much money to offer each player as their individual attendance fee. The amount depends on a COMBINATION of the following factors:
Overall attendance fund (divided into five numeric ranges).
Player's current world ranking (divided into ten numeric ranges).
Whether it is a local tournament for the player (i.e. YES or NO)
Their relationship with the tournament sponsors (i.e. clothing, equipment, or endorsement).
Their previous attendance history at this event (i.e. finalist, played, withdrew before event or withdrew during event) The new system needs to be ready for the next tournament in just a few months' time, so testing schedules will be severely challenged.
Which specification-based technique would be the BEST choice in the circumstances?
A. Pairwise testing.
B. Use case testing.
C. Classification tree (maximum class coverage).
D. Equivalence partitioning.
正解：C

質問 6：
Consider the following fault attack:
"Force all possible incoming errors from the software/OS interfaces to
the application".
Which of the following is the kind of failure you are looking for when using this attack?
A. Front page of an application has incorrect spelling for the company name
B. Application miscalculates total monthly balance due on credit cards
C. Application crashes when unsupported characters are pasted into an input field using the windows clipboard
D. Application fails to display financial numbers in the correct currency format in reports
正解：C

質問 7：
How do user stories and testing relate in an agile project?
A. The tester will typically gather and document the user stories, and use them for testing.
B. User stories provide the user requirement and acceptance criteria being two important inputs for the tester.
C. User stories provide the flow of events which are to be used by the tester to define test cases.
D. User stories drive the regression test.
正解：B

質問 8：
As a test analyst you are involved in the early stages of an acceptance test for a Product Data Management system. You are asked to write test designs and test cases based on use cases. An early version of the system is also already available. It is a known fact that on the implementation level many things will change (including the user-interface). The tests will be carried by end-users with much domain knowledge who have also been involved in the project defining the user requirements and reviewing documentation.
What is the BEST option regarding the level of detail and documentation required for test cases in the project?
A. Concrete test cases only since the end-users have extensive domain knowledge
B. Logical test cases only since the end-user have extensive domain knowledge and many changes are expected thus reducing testware maintenance effort
C. Detailed concrete test cases since many re-runs of the tests are expected
D. Logical test cases supported by concrete test cases to allow for traceability and enable future changes
正解：B

質問 9：
You are testing an ATM based on the following use case;
ATM start screen is showing:
1. The user inserts card
2. The user types in PIN
3. The user selects cash with receipt
4. The user selects 50
5. The user selects no further service
Expected results:
- The ATM provides 50 to the user
- The ATM return the card and balance slip
- The ATM clears the screen
- The ATM returns to start menu
In your test log which of the following could be noted as part of additional attention points?
A. Issues regarding time-behavior
B. Expected results not clearly defined
C. Issues regarding interoperability
D. More test cases needed to achieve full coverage
正解：A
