C++测试Mock库，可以运行时Mock任何函数，包括普通函数，成员函数，静态成员函数，支持Mock虚函数。实现方式是直接运行时修改机器代码。支持gcc/clang/Visual C++，支持x86/x64/arm32。- The C++ mock library for unit testing, it can be used to mock all functions, including trivial functions, member functions, static member functions and virtual functions. It is implemented in modifying binary code in run-time. It supports gcc, clang, Visual C++, and supports x86/x64/arm32.
