Test::use::ok(3pm)

✨ Test::use::ok ✨

okay bestie so this is a page from the Perl Programmers Reference Guide — Test::use::ok(3pm) to be exact — and it's literally the glow-up your test scripts have been waiting for 💅

🎀 NAME 🎀

Test::use::ok — the alternative to Test::More::use_ok. That's it, that's the whole vibe. 💖

🦋 SYNOPSIS 🦋

use ok 'Some::Module';

look at that. a single space is doing SO much work here, i'm obsessed 😭

🌸 DESCRIPTION 🌸

ok so according to the Test::More documentation, the recommendation is to run use_ok() inside a BEGIN block — that way functions get exported at compile-time and prototypes are properly honored. periodt. ✨

basically, instead of writing this:

use_ok( 'Some::Module' );
use_ok( 'Other::Module' );

you should be writing this:

BEGIN { use_ok( 'Some::Module' ); }
BEGIN { use_ok( 'Other::Module' ); }

but here's the thing — and ngl this is so real of us — people often either forget to add BEGIN, or they mistakenly group use_ok with other tests in a single BEGIN block, which "can create subtle differences in execution order." subtle differences!! in execution order!! the chaos 🙈

with this module, you simply change all use_ok in test scripts to use ok, and they will be executed at BEGIN time. iconic behavior. and the explicit space after use makes it clear that this is a single compile-time action — one action, one moment, main character energy 👑

fr fr: that space isn't just cute, it's communicative. it's telling you "hey bestie, this all happens at compile time, as one thing." slay 💅
