I know that basically, CC can be computed as number of decision + 1. In addition, every logical operator in the condition causes CC to increase by 1. But why?
Having the code
if(A || B || C) else... the control flow graph would simply be a node with two outcomes - two branches. So I always thought branch coverage is about covering the edges of the graph, branches, which would mean to the compbound condition to evaluate to TRUE and FALSE.
As for the paths, the paths can only be either TRUE or FALSE, so why the CC inreases with operators if there is no other branch of code run?
