浅析基于因果图法软件测试用例的设计

Analysis on the Design of the Software Test Case Based on Causality

使用黑盒测试方法进行功能性测试是软件测试的重要组成部分,而等价类划分和边界值分析等方法仅考虑了单个输入条件下测试用例的选取方法,本文结合自动化投币洗衣机案例所讨论的因果图法可以分析多个输入条件之间以及输入条件与输出结果之间的各种组合情况,分析各种复杂的功能逻辑,从而生成更加高效的软件测试用例方案。

Using black box testing method for functional testing is an important part of software testing.Equivalence class divi-sion and boundary value analysis method only considers the selection of test cases under the condition of single input method For this,the paper discusses on the cause and effect diagram method with the case of automatic coin-operated washing machine,which can analyze multiple input conditions,and various combinations of input and output results,analyze the function of various complex logic,resulting in more efficient software test cases.
