Editbox之三个框框

自重装系统后，电脑中两个版本的eclipse都驾崩了，起个VS也要花费半年的时间（观赏收费），所以就运用已有的工具STS编了代码，不能用JavaFX很是遗憾，只能在网上找了代码，自己修改后完成了测试。

1. 基本等价类的划分

有效等价类	无效等价类
长度:1到6	长度:0,7
字符:a-z,A-Z,0-9	字符:英文/数字以外字符,控制字符，标点符号

2. 测试用例

编号	test1	test2	test3	输出
1	12345	asdfg	ert234	true,true,true
2	1234567	123	ert	false,true,true
3	123@	123	ert	false,true,true
4	空	123	ert	false,true,true
5	123,	123	ert	false,true,true

按理说应该同时测试各个test（i）为假的情况，但以经验而谈，情况是一样的，就不做脱裤子放屁的事了。
