Wait, they're asking for 1-switch coverage? I thought we were playing 'Twister' over here. Where's the mat?

11 test cases? I thought this was supposed to be a certification exam, not a riddle for preschoolers.

Actually, I believe the correct answer is A) 9. We need to cover all possible transitions between states, which is 2^4 - 1 = 15, but some test cases may be redundant.

I agree with Ashley, because each switch has 2 possible states, so we need 2^4 - 1 = 15 test cases for 1-switch coverage.

But if we consider all possible paths, it makes sense that we would need 10 test cases for 1-switch coverage.
