Which of the test cases below will exercise both outcomes from decision 2? [K3]
A . P = 24, Q = 20, P=24, Q=25
B . P = 36, Q = 36, P=37, Q=35
C . P = 42, Q = 43, P=42, Q=42
D . P = 37, Q = 36, P=35, Q=36
Answer: B
Explanation:
The question asks which of the test cases will exercise both outcomes from decision 2. Decision 2 is represented by node B in the flow graph. Node B has two outcomes: edge 2 (P > Q) and edge 3 (P <= Q). Therefore, to exercise both outcomes from decision 2, we need to choose a test case that covers both edge 2 and edge
Among the options given in this question, only B covers both edge 2 and edge
In B, P =36 > Q =36 for edge 2 and P =37 <= Q =35 for edge
Therefore, B is the correct answer.
