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.
