Whether this is the best or easiest approach, I'm not sure. I came up with it on my own after much searching for freely-available unit testing code in C++. But if anyone can suggest such code, or a better way to go about testing C++ using the Perl Test:: modules, I would love your input.

If you want a C++ xUnit framework you might be interested in taking a look at CxxTest, unit++, CppUnitLite or CppUnit.

While I've not used it myself I've heard good things about CppUnitLite.

(not that there is anything wrong with using Perl ;-)
