NAME

6       Test2::Tools::Ref - Tools for validating references.
7

DESCRIPTION

9       This module contains tools that allow you to verify that something is a
10       ref. It also has tools to check if two refs are the same exact ref, or
11       different. None of the functions in this module do deep comparisons.

SYNOPSIS

14           use Test2::Tools::Ref;
15
16           # Ensure something is a ref.
17           ref_ok($ref);
18
19           # Check that $ref is a HASH reference
20           ref_ok($ref, 'HASH', 'Must be a hash')
21
22           ref_is($refa, $refb, "Same exact reference");
23
24           ref_is_not($refa, $refb, "Not the same exact reference");
25

EXPORTS

27       All subs are exported by default.
28
29       ref_ok($thing)
30       ref_ok($thing, $type)
31       ref_ok($thing, $type, $name)
32           This checks that $thing is a reference. If $type is specified then
33           it will check that $thing is that type of reference.
34
35       ref_is($ref1, $ref2, $name)
36           Verify that two references are the exact same reference.
37
38       ref_is_not($ref1, $ref2, $name)
39           Verify that two references are not the exact same reference.
