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

Question

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?

Answer 1

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

Answer 2

That's a reasonable approach.

I've had very good results both with UnitTest++ and Boost.Test

I've looked at CppUnit, but to me, it felt more like a translation of the JUnit stuff than something aimed at C++.

Update: These days I prefer using Catch. I found it to be effective and simple to use.
