Cyclomatic Complexity

This metric measures each method's cyclomatic complexity by measuring the number of "while", "for", "if", and "switch" statements in a method.

Cyclomatic complexity measures method complexity.

Studies have found that methods with cyclomatic complexity higher than 10 are more error-prone than methods with lower cyclomatic complexity.

By default, Jtest reports an error if this metric's value is not between 0 and 10.

Note: This rule does not test abstract methods, native methods, or any methods that are declared in the interface.
