Test::C2FIT::FileRunner - a runner class operating on (plain) html files.
$runner = new Test::C2FIT::FileRunner(); $runner->run($infile,$outfile);
Either you use this class as a starting point for your tests or your test documents refer to other test documents which shall be processed recursively.
To run your tests, it might be even simplier to use
perl -MTest::C2FIT -e file_runner.
