Hello dear esteemed monks!

Update: Test::Regression

Is there already a module that allows to run a piece of code and, depending on arguments, either write results to a file, or compare with a previous such file? And is there a name for the concept in general? Searching for save load test on CPAN was somewhat cluttered...

So I need something along the lines of:

use Test::More;
use Test::SaveLoad;
use My::Module; # system under test

# load previous results & compare
my $sl = Test::SaveLoad->new( load => $filename );

# save results for future (in Dumper?..)
my $sl = Test::SaveLoad->new( save => $filename );

# do actual testing
plan tests => 1 if $sl->is_testing;

$sl->test( "Basic usecase" => sub {
    My::Module->load_data( id => 42 );
});
# returns eq_or_diff-like line-by-line comparison

It's not that hard to write, but maybe there is something like that?

thank you
