質問 # 51
Which of the following statements are true?
(i) For every development activity there is a corresponding testing
activity.
(ii) Each test level has the same test objectives.

A. (i) and (ii)
B. (i) and (iv)
C. (iii) and (iv)
D. (ii) and (iii)

正解：B

解説：
Option (ii) is incorrect: each test level has a different objective. Option (iii) is also incorrect: test analysis and design should start once the documentation has been completed.

質問 # 61
One of the exit criteria for a SW project was defined as "80% statement coverage".
A test manager submitted the following report:
"We did not measure the statement coverage. However, we ensured 80% branch coverage, therefore the exit criteria was met".
Is the test manager right?

A. Yes. Coverage of 80% of the branches in the control flow guarantees 80% statement coverage.
B. Yes. 50% branch coverage guarantees 100% statement coverage. With 80% branch coverage, the exit criteria is easily met.
C. No. There is not direct relationship. 80% branch coverage does not guarantee 80% statement coverage.
D. No. The relation works the other way. 80% statement coverage guarantees 80% branch coverage
