Abstract—The credibility of software needs to be tested thoroughly with many testing cases before being used. However, more test cases will increase the total software’s developing expenditure. In order to cut the expenditure of software testing as much as possible, we present a method to calculate the minimal test cases for software trustworthiness properties test. First, according to the quality characteristics and specific application background of the software, we determine the composition of software trustworthiness properties and complex interaction between trustworthiness properties with the method of AHP, and then construct the hierarchical structure of trustworthiness properties. Second, based on the hierarchical structure of trustworthiness properties, a top-down comparison matrix was constructed through pair-wise comparison. The eigenvectors of the matrix was calculated and consistency test was done to get the software’s different trustworthiness properties weights. Third, the ratio relationship among trustworthiness properties was calculated and the minimal testing cases at certain confidence level were obtained based on classical statistical hypothesis theory. Finally, we provide an application case to elaborate the process and effectiveness of the method.
