I have a question regarding modified condition/decision coverage that I can't figure out.
So if I have the expression ((A || B) && C)
and the task is with a minimal number of test cases receive 100% MD/DC.
I break it down into two parts with the minimal number of test cases for (A || B)
and (X && C)
.
(A || B) : {F, F} = F, {F, T} = T, {T, -} = T
(X && C) : {F, -} = F, {T, F} = F, {T, T} = T
The '-' means that it doesn't matter which value they are since they won't be evaluated by the compiler.
So when I combine these I get this as my minimal set of test cases:
((A || B) && C) : {{F, F}, -} = F, {{F, T}, F} = F, {{T, -}, T} = T
But when I google it this is also in the set: {{F, T}, T} = T
Which I do not agree on because I tested the parts of this set separately in the other tests, didn't I?
So I seem to miss what the fourth test case adds to the set and it would be great if someone could explain why I must have it?
