Consider the following simplified version of a state transition diagram that specifies the behavior of a video poker game:
What Is the minimum number of test cases needed to cover every unique sequence of up to 3 states/2 transitions starting In the "Start" state and ending In the "End" state?
A . 1
B . 2
C . 3
D . 4
Answer: D
Explanation:
The minimum number of test cases needed to cover every unique sequence of up to 3 states/2 transitions starting in the “Start” state and ending in the “End” state is 4. This is because there are 4 unique sequences of up to 3 states/2 transitions starting in the “Start” state and ending in the “End” state:
Start -> Bet -> End
Start -> Deal -> End
Start -> 1st Deal -> End
Start -> 2nd Deal -> End
