I am learning ISTQB and encountering a question about Statement and Decision coverage in a sample exam of ASTQB org.
There are 4 answer choice:
a. 33% statement, 100% decision
b. 50% statement, 50% decision
c. 100% statement, 75% decision
d. 100% statement, 100% decision
As the answer sheet, the correct one is: C. I understand why 100% statement , but 75% decision. We have 4 SCs:
- A-B-C (test case 1)
- A-B-D-E-F (test case 2)
- A-B-D-A-B-C (test case 3)
- A-B-D-A-B-D-E-F (test case 4)
So the coverage percentage is = the number of run test cases / the total of test cases = 2/4 = 50%. But it is not the same as the answer - 75%.
Am I understanding incorrectly? could you please help me point out what wrong it is and share more ideas on it.
Thank you so much. Learn.
