Model-based testing considering cost, reliability and software quality

The important objectives of software engineering are developing software with high quality, low cost and high reliability. And then people consider more and more about completeness and effectiveness of the technique in order to increase the developers' confidence in software quality. So, the focus of this paper is to minimize the cost of software development during the testing and maintenance stage. Model-based testing and maintenance have been provided in many software development systems. Most software reliability growth models (SRGMs) are typically based on failure data such as number of failures, time of occurrence, failure severity, or the interval between two consecutive failures, whereas other models describe the relationship among the calendar testing, the amount of testing-effort, and the number of software faults detected by testing. In this paper, we propose a new method of software reliability growth models (SRGMs) based on Non-Homogeneous Poisson Process (NHPP) model for reliability growth which during the development test phase. The results provide to be shorter schedule, lower cost and higher quality.
