Test2::Tools::Ref - Tools for validating references.
This module contains tools that allow you to verify that something is a ref. It also has tools to check if two refs are the same exact ref, or different. None of the functions in this module do deep comparisons.
use Test2::Tools::Ref; # Ensure something is a ref. ref_ok($ref); # Check that $ref is a HASH reference ref_ok($ref, 'HASH', 'Must be a hash') ref_is($refa, $refb, "Same exact reference"); ref_is_not($refa, $refb, "Not the same exact reference");
All subs are exported by default.
This checks that
$thing is a reference. If
$type is specified then it will check that
$thing is that type of reference.
Verify that two references are the exact same reference.
Verify that two references are not the exact same reference.
