单测：Google Test框架

原创

git clone https://github.com/google/googletest.git

文件夹	说明
ci	这是Google Test为各个平台提供的快速部署脚本文件夹
docs	这是google test框架的文档
googlemock	这是Google Mock的源码文件夹，它是Google Test的一个扩展，用于编写和运行C++的模拟对象测试。Google Mock提供了模拟对象和行为的功能，用于进行单元测试。
googletest	这是Google Test的核心代码所在的文件夹。它包含了Google Test框架的实现，包括测试框架的主要功能和断言宏等。
