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