Testing Effort-based Software Reliability Growth Models: A Comprehensive Study

In recent era, the use of software systems is growing rapidly. Hence, reliability and customer satisfaction are the most important objectives for software development organizations. Software reliability growth models are essential for checking software reliability. In this paper, we first present an investigative review of testing-effort dependent software-reliability growth models. We discuss the different software reliability growth models with testing-effort behaviors. We then integrate the exponentiated-Weibull testing effort function into a delayed S-shaped software reliability growth model. To validate the proposed model, we present the analysis and estimate of the parameters with authentic data and compare the experimental outcome with the findings of previous models from the articles. Finally, we wrap up the paper by presenting the contributions and by indicating the probable research scope.
