The cyclomatic complexity metric provides the designer with information regarding the number of __________.
Independent logic paths in the program
Cyclomatic complexity, introduced by McCabe, is a software metric computed from the control-flow graph of a program and is the basis of basis-path testing.
Step 1 — It is computed as \(V(G) = E - N + 2\) (edges minus nodes plus two), or as the number of decision (predicate) nodes plus one, or as the number of regions of the flow graph.
Step 2 — The value equals the number of linearly independent paths through the program, which is the number of test cases needed to execute every statement and every branch at least once in basis-path testing.
The metric does not count loops (cycles) as such, it cannot predict the number of errors (it only indicates where errors are likely), and it is unrelated to the count of statements: a long straight-line program has complexity 1.
Independent logic paths in the program option is correct.
