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 accuracy of the test results is not only related to the sample size but also to the number of tests that can be activated in the test. Based on the establishment of the failure mode test model, the test coverage adequacy measure and criteria of the sample set are proposed. The method of determining the elements in the model and the application flow of the metrics and guidelines are given. At last, the feasibility of testing coverage sufficiency metrics and criteria is illustrated through examples.
