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
10 Print (Time, "noon")
11 Endif
12 End
How many test cases are needed to achieve 100 per cent decision coverage?

A.1
B.2
C.3
D.4

정답:
Explanation:
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.

정답:

Question No : 14

The difference between re-testing and regression testing is:

A.Re-testing is running a test again; regression testing looks for unexpected side effects
B.Re-testing looks for unexpected side effects; regression testing is repeating those tests
C.Re-testing is done after faults are fixed; regression testing is done earlier
D.Re-testing uses different environments, regression testing uses the same environment
E.Re-testing is done by developers, regression testing is done by independent testers
