C语言-单元测试(自研)

前沿

单元测试（unit testing），是指对软件中的最小可测试单元进行检查和验证。对于单元测试中单元的含义，一般来说，要根据实际情况去判定其具体含义，如C语言中单元指一个函数，Java里单元指一个类，图形化的软件中可以指一个窗口或一个菜单等。总的来说，单元就是人为规定的最小的被测功能模块。单元测试是在软件开发过程中要进行的最低级别的测试活动，软件的独立单元将在与程序的其他部分相隔离的情况下进行测试。

在网上找了找C语言都没有类似java 的junit单元测试 ,反复测试自己写的模块非常费劲,特别是交叉模块测试的时候根本就无法弄

因为一个程序只允许一个main方法,如果其他地方存在了,那么就会报错,这就导致了测完A模块想要测试B模块就需要把A模块测试的相关内容删除,这样会出现什么问题呢? 如果后期我们对A模块的内容进行了修改,那么是不是需要在重新写一套测试Demo, 这样非常浪费时间和精力 ,没办法只能自己开发一套类似的,来协助本地开发进行测试代码

  1. 实现最小单元以函数进行测试
  2. 实现流程测试
  3. 实现模块交互模块测试

使用前提

自己必须有集合数据结构和hash结构,然后根据下面的代码进行修改即可 ,如果没有可以到我博客里学习

测试结构

在这里插入图片描述

现在我就能随心所欲的测试了,想测试那个方法就测试那个方法,方法之间还可以联动测试,模块和模块还可以交互测试,等等
