Mccabe cyclomatic complexity tool

It is a quantitative measure of independent paths in the source code of a software program. Cyclomatic complexity can be calculated by using control flow graphs or with respect to functions, modules, methods or classes within a software program.

Independent path is defined as a path that has at least one edge which has not been traversed before in any other paths. This metric was developed by Thomas J. McCabe in and it is based on a control flow representation of the program. Control flow depicts a program as a graph which consists of Nodes and Edges. In the graph, Nodes represent processing tasks while edges represent control flow between the nodes.

Flow Graph notation for a program defines several nodes connected through the edges. Below are Flow diagrams for statements like if-else, While, until and normal sequence of flow. Mathematically, it is set of independent paths through the graph diagram. The Code complexity of the program can be defined using the formula —. Basis Path testing is one of White box technique and it guarantees to execute atleast one statement during testing.

It checks each linearly independent path through the program, which means number test cases, will be equivalent to the cyclomatic complexity of the program. As complexity has calculated as 3, three test cases are necessary to the complete path coverage for the above example. ON JS. PRE JS. NEW JS.
