B. A logical collection of test cases
C. A list of boundary values for "advance amount"
D. An approach to regression testing
正解：D

質問 2：
Test objectives for systems testing of a safety critical system include completion of all outstanding defect correction. Regression testing is required following defect correction at all test levels. Which TWO of the following metrics would be MOST suitable for determining whether the test objective has been met? [K2] a. Regression tests run and passed in systems testing
b. Incidents closed in systems testing
c. Planned tests run and passed in system testing
d. Planned tests run and passed at all levels of testing
e. Incidents raised and closed at all levels of testing
A. a and b
B. a and e
C. d and e
D. b and c
正解：B

質問 3：
What if the project isn't big enough to justify extensive testing..?
A. Use risk based analysis to find out which areas need to be tested
B. Use automation tool for testing
C. Both a and b
D. None of the above
正解：A

質問 4：
Which of the following are 'Exit Criteria?'
A. The last executable statement within a component.
B. Acceptance criteria, completion criteria, pass/fail criteria.
C. Coverage of code, schedule, estimates of defect density.
D. Cost overruns.
正解：C

質問 5：
Which of the following statements BEST describes the difference between testing and debugging?
A. Dynamic testing shows failures caused by defects. Debugging finds, analyzes, and removes the causes of failures in the software.
B. Testing pinpoints (identifies the source of) the defects. Debugging analyzes the faults and proposes prevention activities.
C. Dynamic testing prevents causes of failures. Debugging removes the failures.
D. Testing removes faults. Debugging identifies the causes of failures.
正解：A

質問 6：
IEEE 1028 also defines "management review" as a type of review. What is the main purpose of a management review? 1 credit
A. To monitor progress, assess the status of a project, and make decisions about future actions
B. Provide independent evaluation of compliance to processes, regulations, standards etc.
C. Align technical concepts during the design phase
D. Establish a common understanding of requirements
正解：A

質問 7：
What is the main reason for using a pilot project to introduce a testing tool into an organization? [K1]
A. To ensure the tools fits existing processes without change
B. To identify the requirements for using a tool
C. To assess whether the tool will be cost- effective
D. To make a selection between alternative tools
正解：C

質問 8：
In general, why is it NOT a good idea to estimate the testing effort based only on a percentage of development effort? Identify THREE valid reasons. 1 credit
A. The quality of the development estimate may be poor.
B. The percentage based technique only applies to the V life cycle model.
C. The result is almost always a too low estimate for the required test effort
D. Using the same percentage every time does not address the level of risk of the application to be tested.
E. The maturity of the organization, e.g. the quality of the test basis, quality of development testing, configuration management, availability of test tools, also influence the effort needed for testing.
F. It builds on large set of historical data
G. In general bottom-up estimation is always better than top-down estimation.
正解：A,D,E
