对README提出一个指正：
GoogleTest is a testing framework developed by the Testing Technology team with Google’s specific requirements and constraints in mind. Whether you work on Linux, Windows, or a Mac, if you write C++ code, GoogleTest can help you. And it supports any kind of tests, not just unit tests.
