Question 1

Which of the following statements about branch coverage is true?

Options :

A :

The minimum number of test cases needed to achieve full branch coverage, is usually lower than that needed to achieve full statement coverage

B :

If full branch coverage has been achieved, then all unconditional branches within the code have surely been exercised

C :

If full branch coverage has been achieved, then all combinations of conditions in a decision table have surely been exercised

D :

Exercising at least one of the decision outcomes for all decisions within the code, ensures achieving full branch coverage

Answer: D

Question 2
