An approach of software reliability accelerated testing and assessment

In order to increase the effectiveness and efficiency of software reliability testing, software reliability accelerated testing (SRAT) based on mixed testing method was proposed. Mixed testing is composed of both operational testing and directed testing. The corresponding software reliability accelerated testing process was presented. Also a novel software reliability model based on order statistics (SRMOS) was developed to describe software reliability growth phenomenon in the SRAT process. Finally the verification work using Store Management System (SMS) as a case study was done and introduced. Results of the verification work demonstrate clearly that 1) the accelerated testing method can accelerate software reliability testing process dramatically, resolve saturation effect of testing and increase testing efficiency; 2) the proposed model is able to conduct feasible and accurate reliability assessment and describe software reliability growth phenomenon in the SRAT process effectively.
