Test2::Tools::Ref(3) User Contributed Perl Documentation Test2::Tools::Ref(3)

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.
ref_ok($thing)
ref_ok($thing, $type)
ref_ok($thing, $type, $name)
This checks that $thing is a reference. If $type is specified then it will check that $thing is that type of reference.
ref_is($ref1, $ref2, $name)
Verify that two references are the exact same reference.
ref_is_not($ref1, $ref2, $name)
Verify that two references are not the exact same reference.
