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

Answer 1

Cppunit is a direct equivalent of Junit for C++ applications http://cppunit.sourceforge.net/cppunit-wiki

Personally, I created the unit tests in a different project, and created a separate build configuration which built all the unit tests and dependent source code. In some cases I wanted to test private member functionss of a class so I made the Test class a friend class to the object to be tested, but hid the friend declarations when building in "non-test" configurations through preprocessor declarations.

I ended up doing these coding gymnastics as I was integrating tests into legacy code however. If you are starting out with the purpose of unit testing a better design may be simple.

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.

Answer 3

CxxTest is also worth a look for lightweight, easy to use cross platform JUnit/CppUnit/xUnit-like framework for C++. We find it very straightforward to add and develop tests

Aeryn is another C++ Testing Framework worth looking at
