摘　　要：针对软件防危性增长测试的本质特征在于快速降低由于软件失效而导致系统事故的风险,依据重要性取样的统计学原理,结合软件防危性分析,建立了一套集构建软件关联风险剖面、依照关联风险剖面产生测试用例为一体的软件防危性增长测试方法,并给出了测试停止标准。从理论上讲,本方法在快速降低软件事故风险方面比现有软件测试方法更有效。Considering that the object of software safety growth testing is to reduce the risk of accident resulted by software failures sharply, a software safety growth testing method based on the correlative risk profile is presented. In addition, the procedure of constructing the risk profile according to the importance sampling thinking and software safety analyzing methods, as well as the testing cases generating method, is depicted in detail. Finally, the software safety growth testing stopping rule is given. In theory, the method provided above is effective to reduce the software accident risk .
