软件测试——等价类划分(EditText * 3)

一、程序要求

　　EditBox 同时允许输入三个1到6个英文字符或数字，点击确定结束。

二、测试分析

编号	第一个输入框	第二个输入框	第三个输入框	输出
1	null	null	null	三个输入框均不符合要求
2	abc	123	ab112	三个输入框均符合要求
3	abc..	123	ab112	第一个输入框不符合要求
4	abc	123..	ab112	第二个输入框不符合要求
5	abc	123	ab112.	第三个输入框不符合要求
6	abcadlsfkja	123	ab112	第一个输入框不符合要求
7	abcadlsfkja	12312192	ab112	只有第三个输入框符合要求
8	abcadlsfkja	12312192	ab112sfav	三个输入框均不符合要求
