💖 Test::...::Split(3pm) 💖

okay bestie, so this page lives in the User Contributed Perl Documentation section of your manual, and the module it's actually about is Test::Data::Split. it's giving "let's make your test suite parallel-friendly" and honestly? iconic. 🦋

✨ NAME ✨

Test::Data::Split — split data-driven tests into several test scripts.

fr fr that's the whole vibe: you got a big pile of data-driven tests, and this lil guy chops them into separate scripts so your machine can run them all at once. slay. 💅

🌸 VERSION 🌸

version 0.2.2

🎀 SYNOPSIS 🎀

use Test::Data::Split;

# Implements Test::Data::Split::Backend::Hash
use MyTest;

my $tests_dir = "./t";

my $obj = Test::Data::Split->new(
    {
        target_dir => $tests_dir,
        filename_cb => sub {
            my ($self, $args) = @_;

            my $id = $args->{id};

            return "valgrind-$id.t";
        },
        contents_cb => sub {
            my ($self, $args) = @_;

            my $id = $args->{id};

            return <<"EOF";
#!/usr/bin/perl

use strict;
use warnings;

use Test::More tests => 1;
use MyTest;

@{['# TEST']}
MyTest->run_id(qq#$id#);

EOF
        },
        data_obj => MyTest->new,
    }
);

$obj->run;

# And later in the shell:
prove t/*.t

no cap, that's the whole flow. 🫶

💜 DESCRIPTION 💜

This module splits a set of data with IDs and arbitrary values into one test file per (key+value) for easy parallelisation.

that's it, that's the tea. one ID + one value = one lil test file. spread them out, run them everywhere at once, main character energy. ✨

👑 METHODS 👑

🌈 my $obj = Test::Data::Split->new({ %PARAMS })

Accepts the following parameters:

• target_dir — The path to the target directory - a string. (yes, a string, that's the whole thing 🍓)
• filename_cb — A subroutine references that accepts ($self, {id => $id }) and returns the filename.
• contents_cb — A subroutine references that accepts ($self, {id => $id, data => $data }) and returns the contents inside the file.
• data_obj — An object reference that implements the ->list_ids() methods that returns an array reference of IDs to generate as files.

An example for using it can be found in the synopsis. (scroll up bestie, it's right there 💖)

🌟 $self->run()

Generate the files.

that's it. that's the method. go off. 🔥
