For unit (and by extension, regression) testing I use cppUnint or google 
test.  Both ore C++ frameworks, but I think you really benefit from the 
extra expressive power of C++ when writing unit tests.

I have a mock C function generator I use to replace external (to the 
code under test) functions.  The ability to providing generic mock 
functions is where C++ really makes a difference.
