You've already been pointed to resources about CAPTCHAs, so I won't repeat those here. I will warn that they can cause accessibility problems and point out that they are not hard to defeat, and have been being bypassed easily enough for a good few years now.

... so you might want to reconsider using one of these.

[Discipulus]: in other words: i have a contructor that carps on missing arguments and I want to test that it fails correctly, without carping out in the test output
[Corion]: Discipulus: I usually redefine carp to be something that logs the error message... Maybe my $old_carp = \&Carp::carp; { no warnings 'redefine'; sub Carp::carp = sub { push @caught, [caller(), \@_]; die }
