A review on software reliability: metrics, models and tools

Abstract

With the ever increasing dependency on software, its reliability has become a major concern and a key attribute in determining software quality. Estimation and prediction of software reliability are fundamental to develop reliable software systems. In this direction, various techniques concerning quantitative assessment and analysis through metrics, models and tools have been proposed in the last four decades. However, there still exist many challenges. In this paper, we review software reliability focusing on its characteristics, available metrics, modeling techniques and tools.
