|
|
|
Test2::Compare::Ref - Ref comparison
|
|
|
|
=head1 DESCRIPTION
|
|
|
|
Used to compare two refs in a deep comparison.
|
|
|
|
=head1 SYNOPSIS
|
|
|
|
my $ref = {};
|
|
my $check = Test2::Compare::Ref->new(input => $ref);
|
|
|
|
# Passes
|
|
is( [$ref], [$check], "The array contains the exact ref we want" );
|
|
|
|
# Fails, they both may be empty hashes, but we are looking for a specific
|
|
# reference.
|
|
is( [{}], [$check], "This will fail");
