软件测试技术（三）——使用因果图法进行的UI测试

目标程序

较上次增加两个相同的输入框

使用方法介绍

• 因果图法

在Introduction to Software Testing by Paul一书中，将软件测试的覆盖标准划分为四类，logical expressions,syntactic descriptions,graphs,input domain characterizations,就我所学的内容来看，等价类划分属于input domain characterizations，控制流与数据流测试属于graphs，而因果图法属于logical expressions。它从用自然语言书写的程序规格说明的描述中找出因（输入条件）和果（输出或程序状态的改变），可以通过因果图转换为判定表。

• 步骤

列出因和果

画出因果图

根据因果图画出判定表

如变量太多，可先将判定表进行简化，之后设计测试用例

原因与结果

因果图

判定表
