用例编号：每一条都拥有独立的编号
所属系统：表示当前测试用例功能是属于哪个系统的
所属模块：属于哪个系统下的哪个模块当中功能
用例标题：1.所有用例标题必须以验证进行开头
             2.测试用例标题不要带上不确定的词汇，是否、好像
             3.测试用例当中明确自己的输入的场景以及输入的条件  1990.1
             4.必须包含预期结果，我执行这个用例的时候想要达到的一个结果
前置条件：1.可以写省略或者是通过测试用例步骤，所有功能都需要进行登录-->可以将登录写在前置条件
                   2.测试的具体功能，使用的工具
用例步骤：1.如果你的用例执行失败了，他就是一个bug。开发会根据你的用例步骤来复现bug。用例步骤一定要清晰
                   2.写步骤的时候，每一个节点步骤都必须清晰，包含自己所有输入的情况。输入1990.1
预期结果：编写这条测试用例，所想要达到的结果
实际结果：针对这条测试用例，进行执行验证之后得到的结果，成功还是失败。
编写人：实际情况
执行人：实际情况
