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