This project packages UnitTest++ conveniently as an Xcode framework to make adding unit tests to your project that much easier.
Open the project, build and drag build/Release/UnitTest++.framework to your /Library/Frameworks folder. Xcode will now see it as an additional framework you can add as a dependency of an existing project.
UnitTest++ is a lightweight unit testing framework for C++, written and maintained by Noel Llopis and Charles Nicholson.
