Study of A Method of Optimizing Test Case
一种精简测试用例方法的研究

In the paper,the concept of place-state(PS) of system is supposed with analyzing system state under test- ing. Some otherness occurs between fact PS and excepted PS as testing. Study of the action relation between test data and PS is based on the fuzzy of otherness. Two theorems of fuzzy inference of fuzzy intersection are proved. And the required test case and its structure method are put forward. The application of simple required test case is effective on cutting down the number of test case under the prerequisite of ensuring test quality. The action relation can be regard- ed as fuzzy transformation. That use the arithmetic of the transformation to check test results is both scientific and simple.
