B. Charter outlining tasks (tests) to be performed and objectives to be met, plus a set of heuristics to follow

D. Charter outlining objectives to be met, plus a set of heuristics to follow
正解：B

A. Classification Tree Method
B. State Transition Testing
C. Boundary value analysis
D. Equivalence Partitioning
正解：B

質問 3：
Defects are discovered through test analysis and design because...
A. the author of the test basis will have made errors
B. the testers' mindset is focused on finding defects
C. developers are involved in writing test cases
D. the cost of fixing a defect will increase if found later on
正解：A

質問 4：
Which of the following is NOT an example of a typical pre-condition for test execution?
A. Defined level of requirements coverage achieved
B. A process for managing identified defects
C. Thoroughly specified test procedures
D. A properly configured test environment
正解：A

質問 5：
Scenario "Banking Project"
As a test analyst in the banking domain you have received the following requirement:
"The system shall allow cash advances of at least 200 Euros for all supported credit cards. The correct list of credit cards is American Express, Diners, VISA, Mastercard and Eurocard." Working on a banking project, one of the exit criteria in the test plan requires documentation of successful cash advances of at least 500 Euros for all supported credit cards.
After test execution, a complete list of cash advance test results shows the following:
a) American Express allowed advances of up to 1000 Euros
b) Visa allowed advances of up to 500 Euros
c) Eurocard allowed advances of up to 1000 Euros
d) Mastercard allowed advances of up to 500 Euros
Which of the following statements is true?
A. The exit criterion fails due to the discrepancy between American Express and Eurocard on one hand and Visa and Mastercard on the other hand
B. The exit criterion passes because all supported cards allow cash advances of at least the minimum required amount
C. The exit criterion fails due to excessive advances for American Express and Eurocard
D. The exit criterion fails because no documentation of Diners credit card test results exists
正解：D

質問 6：
Scenario "Banking Project"
As a test analyst in the banking domain you have received the following requirement:
"The system shall allow cash advances of at least 200 Euros for all supported credit cards, The correct list of credit cards is American Express, Diners, VISA, Mastercard and Eurocard. For the 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 PlN 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
