Test2::...arnings(3pm)

💖 NAME 💖

Okay bestie, welcome to the Test2::...arnings(3pm) page — this is the Perl Programmers Reference Guide version, and the module is Test2::Tools::Warnings: Tools to verify warnings ✨

🦋 DESCRIPTION 🦋

This is a collection of tools that can be used to test code that issues warnings. That’s the whole vibe, fr fr: warning-making code goes in, these little helpers check what came out 🫶

✨ SYNOPSIS ✨

use Test2::Tools::Warnings qw/warns warning warnings no_warnings/;

ok(warns { warn 'a' }, "the code warns");
ok(!warns { 1 }, "The code does not warn");
is(warns { warn 'a'; warn 'b' }, 2, "got 2 warnings");

ok(no_warnings { ... }, "code did not warn");

like(
    warning { warn 'xxx' },
    qr/xxx/,
    "Got expected warning"
);

is(
    warnings { warn "a\n"; warn "b\n" },
    [
        "a\n",
        "b\n",
    ],
    "Got 2 specific warnings"
);

🎀 EXPORTS 🎀

All subs are exported by default — literally all of them, no extra import drama 💅

• $count = warns { ... } — returns the count of warnings produced by the block. This will always return 0, or a positive integer.
• $warning = warning { ... } — returns the first warning generated by the block. If the block produces more than one warning, they will all be shown as notes, and an actual warning will tell you about it.
• $warnings_ref = warnings { ... } — returns an arrayref with all the warnings produced by the block. This will always return an array reference. If there are no warnings, this will return an empty array reference.
• $bool = no_warnings { ... } — return true if the block has no warnings. Returns false if there are warnings.
