摘要： 试验设计在软件测试中的应用已发展到组合测试阶段，组合测试的一个重要问题是确定因素组合需要覆盖到何种程度。该文提出了一个系统的软件失效因素数目分析方法，从相似软件或同领域软件失效与因素数目之间的关系估计被测软件的失效规律，进而确定组合测试的测试数据需要覆盖的因素组合水平。应用该方法能使组合测试生成的测试数据更加有效。

Abstract: The application of design of experiments for software test has developed to the age of combinatorial test, an important issue of which is in what degree parameters interaction is required to be covered. A systemic method to analyzing the amount of parameters resulting in software failures is presented. In the method, failure rules of software under test can be got from the relationship between failures and the parameters’ number of similar software or applications in the same field. Consequently, the level of parameters combination which should be covered by combinatorial test data set can be defined. By using it, combinatorial test method can generate more effective test data.
