In fact I use unit testing to test a Ruby wapper over a C++ tool that 
that takes a long time to execute. In fact it is not for testing the C++ 
app but to test the wrapper.

I also use it to test our VC++ build and packaging system. Even if I 
made small unit test, the whole process takes up to 13 mins.
