How do you implement unit-testing in large scale C++ projects?

c++, coding-style, unit-testing

Solution

There are many Test Unit frameforks for C++. CppUnit is certainly not the one I would choose (at least in its stable version 1.x, as it lacks many tests, and requires a lot of redundant lines of codes). So far, my preferred framework is CxxTest, and I plan on evaluating Fructose some day.

Any way, there are a few "papers" that evaluate C++ TU frameworks :

- Exploring the C++ Unit Testing Framework Jungle, By Noel Llopis

- an article in Overload Journal #78

Problem

I believe strongly in using unit-tests as part of building large multi-platform applications. We currently are planning on having our unit-tests within a separate project. This has the benefit of keeping our code base clean. I think, however, that this would separate the test code from the implementation of the unit. What do you think of this approach and are there any tools like JUnit for c++ applications?
