Abstract:

In this paper we develop a software reliability assessment tool, called M-SRAT: Metrics-based Software Reliability Assessment Tool, by using several testing metrics data as well as software fault data observed in the testing phase. The fundamental idea is to use the metrics-based software reliability models proposed by the same authors. M-SRAT is written in Java language with 54 classes and 8.0 KLOC, where JDK1.5.0 9 and JFreeChart are used as the development kit and the chart library, respectively. This tool can support (i) the parameter estimation of software reliability models via the method of maximum likelihood, (ii) the goodness-of-fit test under several optimization criteria, (iii) the assessment of quantitative software reliability and prediction performance.
