这篇博客是对上星期的EditBox的一个扩展。上周博客简单的列出EditBox的等价类划分与测试用例设计，此篇博客将一个EditBox扩展为三个EditBox。原理跟前面完全相同，下面直接上结果：
等价类划分：
| 有效等价类 | 无效等价类 |
| 字符串a,b,c正确 | a,b正确,c错误 |
| a,c正确,b错误 | |
| b,c正确,a错误 | |
| a,b错误,c正确 | |
| a,c错误,b正确 | |
| b,c错误,a正确 | |
| a,b,c错误 |
根据等价类，简单设计测试用例：
| a | b | c | 结果 |
| a123456 | a4 | vv | a长度应为1-6 bOK cOK |
| a2 | df | aOK b长度应为1-6 cOK |
|
| ss | a长度应为1-6 b长度应为1-6 cOK |
下面是界面及代码：
