In this paper, we develop a new testing-coverage software reliability model with the uncertainty of operating environments. Examples are included to illustrate the goodness-of-fit of proposed model and several existing non-homogenous Poisson process (NHPP) models based on four sets of failure data collected from software applications. The explicit mean value function solution for the proposed model is presented. The results show that the proposed model fits significantly better than other existing NHPP models based on three criteria such as mean squared error, predictive power and predictive ratio risk.
