测试性试验中样本集的测试覆盖充分性研究

Study on the Test Cover's Adequacy for the Sample Set in the Testability Demonstration

测试性试验结果的准确性不仅与样本量有关,还与试验中能够激活的测试数量有关。在建立故障模式测试模型的基础上,提出了样本集的测试覆盖充分性度量和准则。给出了模型中要素的确定方法,以及该度量和准则的应用流程。最后通过实例应用说明了测试覆盖充分性度量和准则的可行性。

The result’s accuracy of testability demonstration is no only related to the sample size, but also related to the number of tests to be activated in the demonstration. Based on the setting up o failure mode’s testing model, the adequacy measurement and crite rion of test cover for the sample set are proposed. The method of determining elements of the model is presented, and the application flow of the measurement and criterion is also presented. At last, a case shows the feasibility of the adequacy measurement and crite rion of test cover.
