摘要: 从软件可靠性测试的基本特点出发,分析软件可靠性测试用例之间存在的相似性;并利用模糊数学中的一系列原理,对软件可靠性测试用例特征进行处理;对测试用例相似性进行组合模糊判别,若相似性达到一定置信度,则对该测试用例进行不执行而累积测试时间的处理过程,从而加速软件可靠性测试.该方法只对软件可靠性测试用例特征进行分析处理,对软件可靠性评估模型没有影响,因此一定程度上减小了评估误差,同时在软件可靠性加速测试方面进行了新的尝试.

Abstract: Based on the fundamental feature of software reliability testing (SRT), similarity exited between the SRT test cases was analyzed. A serious theory in fuzzy mathematics was used to deal with the data character of test case. A new complementary fuzzy discrimination method was put forward to judge the similarity, the test case with a high similarity would not be executed but accumulate the testing time and then speed up the SRT. This method does nothing but the treatment for test case and has little impact on evaluation model. Meanwhile, it is a new attempt to software reliability accelerated testing (SRAT).
