Cyclomatic complexity method comes under whoch testing method

Cyclomatic complexity is a white-box testing method used to measure the number of linearly independent paths through a program's source code. It requires examining the internal structure of the code (control flow graph), which is the defining characteristic of white-box testing. Black-box testing (B) focuses on inputs and outputs without examining internal structure, while green-box (C) and yellow-box (D) are not standard testing methodology classifications.
