For the last few years I've been trying to add unit tests to all of my personal projects. I do a bit of game modding in my spare time and those are the last projects that ended up getting unit tests, but they were also the ones I most wanted to add tests for because they're the most complicated and also the most time-consuming to test manually. The biggest hurdle to start with was that the Visual Studio projects are all set up in such a way that integrating Microsoft's C++ unit test framework either requires you to (probably) recreate the project the right way, or to hack around with scripts to create a working test runner. Setting up Boost tests might be less painful. But once that is done, my next hurdle was mocking out the game engine. Not overly difficult as the engine exposes a nice API but still time consuming. Now that that's done it's been good start adding tests, though I haven't added any tests for anything too complicated yet.
