Mocking C++

" summary

Creates mocks by overwriting vtable entries and filling a fake vtable with stub function pointers, uses reinterpret_cast hacks to plant member function pointers and a stub that throws exceptions from stubs to signal unexpected calls. Shows how expectations are recorded as argument tuples and validated in destructors, reports working on OS X Linux Windows and embedded ARM with MSVC valgrind and other dynamic checkers, claims cross‑platform reliability, and points to hip amongst and comply for safer C++14/11 implementations.
