Modelling the Failure Rate Function in Coverage and Software Reliability Growth
Yoong‐Yang Park, Young Soon Kim, Jae Heung Park · Asian Journal on Quality · 2004
There is a new trend of incorporating software coverage metrics into software reliability modelling. This paper proposes a coverage‐based software reliability growth model. Firstly, the failure rate function in coverage is analytically derived. Then it is shown that the number of detected faults follows a Nonhomogeneous Poisson distribution of which intensity function is the failure rate function in coverage. Practical applicability of the proposed models is examined by illustrative numerical examples.
