=head1 NAME
Test2::Compare::Custom - Custom field check for comparisons.
=head1 DESCRIPTION
Sometimes you want to do something complicated or unusual when validating a
field nested inside a deep data structure. You could pull it out of the
structure and test it separately, or you can use this to embed the check. This
provides a way for you to write custom checks for fields in deep comparisons.
=head1 SYNOPSIS
my $cus = Test2::Compare::Custom->new(
name => 'IsRef',
operator => 'ref(...)',
code => sub {
my %args = @_;
return $args{got} ? 1 : 0;
},
);
# Pass
is(
{ a => 1, ref => {}, b => 2 },
{ a => 1, ref => $cus, b => 2 },
"This will pass"
);
# Fail
is(
{a => 1, ref => 'notref', b => 2},
{a => 1, ref => $cus, b => 2},
"This will fail"
);
=head1 ARGUMENTS
Your custom sub will be passed 4 arguments in a hash:
code => sub {
my %args = @_;
# provides got, exists, operator, name
return ref($args{got}) ? 1 : 0;
},
C<$_> is also localized to C<got> to make it easier for those who need to use
regexes.
=over 4
=item got
=item $_
The value to be checked.
=item exists
This will be a boolean. This will be true if C<got> exists at all. If
C<exists> is false then it means C<got> is not simply undef, but doesn't
exist at all (think checking the value of a hash key that does not exist).
=item operator
The operator specified at construction.
=item name
The name provided at construction.
=back
=head1 METHODS
=over 4
=item $code = $cus->code
Returns the coderef provided at construction.
=item $name = $cus->name
Returns the name provided at construction.
=item $op = $cus->operator
Returns the operator provided at construction.
=item $bool = $cus->verify(got => $got, exists => $bool)
