The nodes in the graph indicate the smallest group of commands of a program, and a directed edge . It directly measures the number of linearly independent paths through a program's source code. Since the basis path testing technique takes into account the complexity of the software (i.e., program or module) while computing the cyclomatic complexity, therefore it is intuitive to note that testing effort in case of basis path testing is directly proportional to the complexity of the software or program. 5 = 9 - 6 + 2 (no further explanations are given in the paper as to how) Summaries of technical papers, case studies, and empirical results are presented in the appendices. Test Cases for the Commission It is a practice that if the result of cyclomatic complexity is more or a bigger number, we consider that piece of functionality to be of complex nature and hence we conclude as a tester; that the piece of code/functionality requires in-depth testing. Project Analyzer supports three alternative cyclomatic complexity metrics. 11. Sometimes people write programs to solve problems, and in that case the essential complexity of the problem often finds its way into the program, but there's always other complexity involved as well.
