got the basic tests in place, got the types organized how I want this to work. Still...

[gitmo/MooseX-Dependent.git] / t / 01-basic.t

	use strict;

	use_ok 'MooseX::Meta::TypeConstraint::Dependent';
	use_ok 'Moose::Util::TypeConstraints';

	## A sample dependent type constraint the requires two ints and see which
	## is the greater.
	
	ok my $int = find_type_constraint('Int') => 'Got Int';
	
	my $dep_tc = MooseX::Meta::TypeConstraint::Dependent->new(

		dependent_type_constraint=>$int,

			return $constraining_value > $check_value ? 0:1;

	## Does this work at all?
