To increase the precision of software reliability evaluation and prediction,a testing-coverage based non-homogeneous poisson process software reliability model is developed.Considering the information of testing-coverage,the model can describe the software testing process much more precisely,and can avoid inaccurate reliability evaluation resulting from inadequacy of testing.Combining with change-point theory,a testing-coverage based on software reliability estimation method is proposed.This method can solve the problem of the software failures not following a same distribution during testing process due to the changed profile which often happen in real testing work.Finally,the precision and efficiency of the presented method is validated by practical application.
