Consider the following pseudo code: 1 Begin 2 Read Time 3 If Time < 12 Then 4 Print(Time, "am") 5 Endif 6 If Time > 12 Then 7 Print(Time 12, "pm") 8 Endif 9 If Time = 12 Then 1 0 Print (Time, "noon") 1 1 Endif 1 2 End How many test cases are needed to achieve 100 per cent decision coverage?
Correct Answer: C
The three decisions are in sequence and the conditions are all mutually exclusive (if any one is true the others must be false). Hence a test case that makes the first decision true will make the second and third decisions false and so on. So test case 1 (say Time = 6) would exercise the path True, False, False, test case 2 (say Time = 15) would exercise the path False, True, False. Test case 3 would have to be Time = 12. This combination achieves 100 per cent decision coverage because each decision has been exercised through its true and its false outcomes.
