Test2::Tools::Ref(3) Perl Programmers Reference Guide 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.

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.
