The research of software reliability models focuses on how to make reliability models accord with actual situation.The aim of it is improving the ability of fitting accuracy for software reliability models and predicting the software's fault behavior in the future better.The assumptions of classical non-homogeneous Poisson process models disregard imperfect debugging and the introduction of new errors.In addition,the consumption of resources is not considered either.Think the consumption of resources in test process,test environment,and the input level of tester can affect the results of test.Meanwhile,perfect debugging and imperfect debugging in the test process are also considered,and a new NHPP model with respect to test efficiency is proposed.After contrasting with some released models,the new model shows better performance to fit data and theoretically can be applied into projects.
