Analysis of risk in information system using cyclomatic complexity

Abstract

Software testing is an important part of the software development life cycle.Testing from starting stages will allow us to avoid the trouble of fixing bugs in later stages. There are many testing techniques that are used to discover errors or any software bugs found during the implementation.One of the procedure for testing is through ascertaining cyclomatic unpredictability which centers around structure of source code. Cyclomatic complexity calculates the paths and control points.Cyclomatic complexity is one of the software metric that is widely used to measure the complexity of a program. In a program there may be several modules, methods or classes with respective these aspects cyclomatic complexity can be calculated. cyclomatic complexity is developed by Thomas J.McCabe in 1976 on basis of control flow representation in a program. our target in the project is to find the cyclomatic complexity for any given source code. if the cyclomatic complexity is low then the hazard to alter code is lower and source code will be easier to understand and maintain and in case if the cyclomatic complexity is high the risk to modify code is higher and source code will be tough.
