Comparing TMMi and TPI, which is not a valid reason for choosing either TPI or TMMi? 2 credits

A. If the scope of test performance improvement covers all test levels, TMMi is preferred since TPI focusses mainly on black-box testing.
B. If the organization is already applying CMMI, TMMi may be preferred since it has the same structure and uses the same terminolog
C. TMMi addresses management commitment very strongly and is therefore more suitable to support a top-down improvement process.
D. TPI is much more a bottom-up model that is suitable for addressing test topics for a specific (test) project.
E. TMMi can only be used with the traditional V model,whereas TPI can be used with all types of software life cycles.

Correct Answer:D

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

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.
