This paper investigates a SRGM (Software reliability growth model) based on NHPP (non-homogeneous Poisson process) which incorporates the 4p-Kappa testing effort function. Testing Software reliability is generally a key factor in software quality. Reliability is an essential ingredient in customer satisfaction. In software development process reliability conveys the information to managers to access the amount of testing effort and time at which software release into the market. Many papers are published in this context. Performance application of proposed model is demonstrated through real datasets. The experimental results shown that the model gives an excellent performance compared to other models. We also discuss the optimal release time based on reliability requirement and cost criteria.
