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

Answer 1

I use UnitTest++. The tests are in a separate project but the actual tests are intertwined with the actual code. They exist in a folder under the section under test. ie:
MyProject\src\ <- source of the actual app
MyProject\src\tests <- the source of the tests
If you have nested folders (and who doesn't) then they too will have their own \tests subdirectory.
