Google Test is a unit testing library for the C++ programming language, based on the xUnit architecture. The library is released under the BSD 3-clause license. It can be compiled for a variety of POSIX and Windows platforms, allowing unit-testing of 'C' sources as well as C++ with minimal source modification. The tests themselves could be run one at a time, or even be called to run all at once. This makes the debugging process very specific and caters to the need of many programmers and coders alike.
