in reply to Testing Zork-style game

K.I.S.S. Assuming that your using standard IO for your input and output, your test scripts could do something like:

use File::Slurp; use Test::More ...; ... system( 'perl < testfile.1 >output.1' ); my $out = Slurp( 'output.1' ); my $expected = Slurp( 'expected.1' ); ok( $out eq $expected );

Substututing zork < testfile.1 > output.C.1 (C-version) or lisp zork.whatever? < testfile.1 >output.lisp.1 for the perl in the system command allows you to run the same tests against all three versions.

Adding a debug option (to at least one version) that copies both the input and output to a separate files whilst the game is being played would allow you to generate your tests interactively with that version and then supply the input to the other versions and test their output was the same.

    Except that you'd want to write
    ok( $out eq $expected );
    is( $out, $expected );
    If the strings are really long and hard to read through, look at Test::LongString.

      Test::Differences can be useful for this too.
