C++ – Unit testing for C++ code – Tools and methodology


I'm working on a large c++ system that is has been in development for a few years now. As part of an effort to improve the quality of the existing code we engaged on a large long-term refactoring project.

Do you know a good tool that can help me write unit tests in C++? Maybe something similar to Junit or Nunit?

Can anyone give some good advice on the methodology of writing unit tests for modules that were written without unit testing in mind?

Best Solution

Applying unit tests to legacy code was the very reason Working Effectively with Legacy Code was written. Michael Feathers is the author - as mentioned in other answers, he was involved in the creation of both CppUnit and CppUnitLite.
