I use the Test::Harness module all the time in testing my C++ code. All it took was to write an extremely minimal C++ class to emulate the behavior of Test::More, then put appropriate targets in a Makefile to do the following things when I type make test:

• Compile the C++ tests into executables, linking against my Test::More emulation class.
• Create a one-liner Perl program for each executable that simply runs the executable and spits its output to STDOUT (because Test::Harness expects to be running Perl programs). Something like

  #!/usr/bin/perl
  print `./foo.t`;
  [download]

  where foo.t is the C++ test executable.
• Run the one-liners using Test::Harness, like this:

  perl -e 'use Test::Harness qw(&runtests $$verbose); $$verbose=${VERBOS
  +E}; runtests @ARGV;' ${TEST_SCRIPTS} 2>/dev/null
  [download]

  where ${VERBOSE} is either 1 or 0 and ${TEST_SCRIPTS} is the list of Perl one-liners.

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.
