20111018 boost and gtest
This document provides an overview and summary of Boost and Google Test (gtest). It discusses key Boost libraries like smart pointers, assign, foreach, and bind. It explains how Boost handles memory management and containers. It also covers the basics of gtest like writing assertions and test fixtures. The document recommends gtest as a lightweight unit testing framework compared to Cppunit.
