Abstract

This paper describes an integrated method using var ious techniques to improve testing efficiency. It uses several empirical techniques (capture-recapture methods, an experience-based method, and a selection method for software reliability growth models) and describes ways to combine the defect estimates obtained to make release decisions. Results of a case study applying the integration method to project data from a large software product from industry demonstrate that the integrated method can im prove the efficiency of system test. Based on post-release data and interviews with the test manager, the method rec ommended the right release decisions using estimations of remaining defect content.
