NAME

Test2::Tools::Warnings - Tools to verify warnings.

CONTENTS

DESCRIPTION

This is a collection of tools that can be used to test code that issues warnings.

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.
$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 1 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 warning this will return an empty array reference.
$bool = no_warnings { ... } Return true if the block has no warnings. Returns false if there are warnings.
