In this method cyclomatic complexity is used to determine the number of linearly independent paths and then test cases are generated for each path. It helps to determine all faults lying within a piece of code. In this technique, control flow graphs are made from code or flowchart and then cyclomatic complexity is calculated which defines the number of independent paths so that the minimal number of test cases can be designed for each independent path.
