Not that I've found. I'm in the process of refactoring the code (one h/cpp per class, etc). I also grabbed googletest and plan to add a few unit tests to get the ball rolling. The refactoring part might be a hinderance to adoption in the master branch (due to the large amount of change), but I do plan to keep it updated with the master.
I haven't used googletest. How does it compare to cppunit?
I've been thinking about splitting out the files, too. No functional changes, just moving things around. I think that might help its adoption into the main trunk.
