Testing batch programs is generally easier than testing interactive
programs.  Instead of having to "talk" to the program, you just spawn
it and see what output it produces, or what exit code it terminates
with.

The calc testsuite in the DejaGnu distribution is a good example.

You'll either need to instrument your C++ program so that you can unit
test your function (if that's what you're trying to do), or use the
C/C++ unit testing support that was recently introduced into DejaGnu.

Can you elaborate?
