Software testing in the debugging process is more efficient if it knows, in advance, to reduce costs in terms of changes in the software reliability and testing costs. In this process, essential items for software development are the reliability, cost, and consideration of release time. In this paper, the software reliability growth cost model based on Non-Homogenous Poisson Process (NHPP) about the property of learning effect for delayed software s-shaped reliability model was proposed, that was considered the actual number of faults removed in the software operation period after release time. Then discuss the relationship between release time and software testing-effort for determine the optimal release time so that can minimize the cost of software development and get more profit. Finally, according to some empirical studies, directly explain the effect of different parameters about the optimal software release time during testing process.
