Hi I am not sure what is the right forum to publish this in (here or in the C++ forum) But I coudln't find any information about it too, which is odd. Anyway, Unit testing in C++: Since it is not as popular as unit testing in other high level languages, I need your recommendations and insights. I have a lot of legacy code- I was just given a project to which I have to have covered by at least 70% unit tests. I need to do a lot of refactoring. Different tools (mocking tools) offer different things and has different limitations. So it might be smarter to ask the people who have already done this and know better than I do - what do you use? Is there a mocking tool (along with a supported testing framework) that can mock concrete classes, virtual, static and non static method, private methods, etc? Thanks a lot for your help:)
