A generalized software reliability growth modeling with testing-domain: model and application

摘要

The set of modules and functions in the software system, which is influenced by the executed test-cases, is called a testing-domain, and it spreads with the progress of testing. In this paper, we propose a testing-domain dependent software reliability growth model considering the skill-factor of test-case designers where it is assumed that the fault-detection possibility growth rate and the testing-domain growth rate are not equivalent in the faultdetection process. This model based on a nonhomogeneous Poisson process is defined as a generalized testing-domain dependent software reliability growth model which improves the conventional model in terms of goodness-of-fit. Further, using several evaluation criteria, we discuss its goodness-of-fit for several actual data sets in comparison with the conventional model. Finally, numerical illustrations of software reliability assessment are shown.
