Cyclomatic Complexity (v(G)) is a measure of the complexity of a module's decision structure. It is the number of linearly independent paths and therefore, the minimum number of paths that should [..]

Actual Complexity (ac) is the number of independent paths traversed during testing.

Module Design Complexity (iv(G)) is the complexity of the design-reduced module and reflects the complexity of the module's calling patterns to its immediate subordinate modules. This metric diff [..]

Essential Complexity (ev(G)) is a measure of the degree to which a module contains unstructured constructs. This metric measures the degree of structuredness and the quality of the code. It is used to [..]

pv(G) is a measure of the degree to which a module contains extremely unstructured constructs.

S0 measures the amount of interaction between modules in a system.

S1 measures the amount of integration testing necessary to guard against errors.

OS1 quantifies the number of tests necessary to fully integrate an object or class into an OO system.

gdv(G) quantifies the cyclomatic complexity of a module's structure as it relates to global/parameter data. It can be no less than one and no more than the cyclomatic complexity of the original f [..]

Data Complexity Metric (DV) quantifies the complexity of a module's structure as it relates to data-related variables. It is the number of independent paths through data logic, and therefore, a m [..]
