Define Cyclomatic complexity?
Show answer Hide answer
Answer: B. White box testing
Explanation
Cyclomatic complexity is a white-box testing metric that measures linearly independent paths through program source code. White-box testing relies on internal knowledge of code structure to design thorough execution test cases. Calculating this metric reveals the structural complexity of a function and guides white-box test coverage. Thomas J. McCabe introduced cyclomatic complexity as a software metric based on control flow graph theory. The metric is calculated using the number of edges, nodes, and connected components within a control graph. Higher complexity values indicate difficult maintenance, lower readability, and a higher probability of hidden defects.
Black box testing evaluates functionality based strictly on requirements without examining internal source code structure. Yellow box testing is a fictional term not recognized within standard software engineering testing methodologies. Green box testing does not exist as a formal classification within software testing or quality assurance taxonomies.
