Testing-Coverage Dependent Software Reliability Growth Modeling and Its Applications

Abstract

We discuss software reliabil- ity growth modeling considering with testing- coverage. The testing-coverage is one of the im- portant metrics related to the software reliabil- ity growth process. First we develop an alter- native testing-coverage function to describe time- dependent behavior of testing-coverage maturity process. Then, we propose a software reliabil- ity growth model by formulating the relation- ship between the testing-coverage maturity process and the software reliability growth process. And we derive several software reliability assessment measures which are useful metrics for quantita- tive assessment of software reliability. Finally, we show numerical examples of software reliabil- ity analysis based on the proposed model by using an actual data set.
