Reliability Assessment of Component Based Software by using Basis Path Testing

For development of a software, the best model which can be selected in a Software Development Life Cycle is Component Based Software Development (CBSD). To develop a new software it requires lots of team effort with professional and high level logics which requires more time if they have to build it from the scratch. In many situations a new development involves to reuse the existing modules of other developed software which helps in reduction of time taken in development phase along with team effort. For these reasons the software should be developed in the form of components. Thus, reliability of a Component is an important factor to be considered. This paper aims to demonstrate a case study for estimating the reliability of a Component Based Software (CBS) and their integration with other modules. A component of a developed software is selected to find the test cases need to be generated by calculating and determining the Cyclomatic Complexity. The Cyclomatic Complexity will provide a numerical value with different approaches which are provided with it. This approach provides a calculated procedure for justifying the reliability of that component of a developed software.
