【简答题】
一个系统的登录操作规格说明如下： 登录对话框有两个数据输入：用户名和密码，登录操作对两个输入数据进行检查，要求用户名中只能包含字母和数字(字母不区分大小写)，密码可以包含任何字符，用户名和密码都不能为空且长度不限。当用户名或密码为空时，则登录失败并提示对应的出错信息；当用户名不正确或用户名不存在的或密码错误时，则登录失败并提示以下三种相应的出错信息：用户名不合法(即包含有非字母、非数字字符)，或用户名不存在，或密码错误；当用户名和密码都正确时，则显示登录成功信息，完成登录。 假设正确的用户名是abcd123，密码是123456。 使用等价类方法为上述规格说明设计等价类表和测试用例。
