This paper provides a method of variable integrity testing to detect the faults of software By checking the definition domain of the variable itself and the restriction condition of consistency between variables, we only need to determine the bound of each output data, rather than the exact value Although the output of testing case cannot be easily caught, this method can improve the efficiency of detecting faults Furthermore, the checking point is not limited to the final output place, but spreads over the reference places in the program code to key variables just like those at the checkpoints under debugging As a consequence, the testing becomes more precise

由于软件测试用例的输出部分很难确定，而通过测试变量自身的定义域和变量间的一致性约束关系，只需要确定输出值的范围而不用知道其确切的值，就可以提高了错误检测的效率同时，检测的范围不局限于程序最后的输出结果，而是散布在程序中的各个有意义的变量，正如调试过程中设置断点观察的那些变量，使得检测错误更加精准1 引言软件测试的本质在于针对要测试的内容确定一组测试用例[1] 测试用例分为输入和输出两部分功能测试和结构测试等基本的软件测试方法，都比较关心测试用例的输入部分定义域的确定，而对测试用例的输出部分考虑得较少例如，边界测试和等价类测试[2 ] 只考虑测试用
