NAME Test::TypeConstraints - testing whether some value is valid as (Moose|Mouse)::Meta::TypeConstraint SYNOPSIS use Test::TypeConstraints qw(type_isa); type_isa($got, "ArrayRef[Int]", "type should be ArrayRef[Int]"); DESCRIPTION Test::TypeConstraints is for testing whether some value is valid as (Moose|Mouse)::Meta::TypeConstraint. METHODS type_isa type_isa($value, $type); type_isa($value, $type, $test_name); type_isa($value, $type, $test_name, %options); Performs a type check against the $value using the $type. $type can be a class name, a Moose/Mouse type name, Moose/Mouse::Meta::TypeConstraint object or Moose/Mouse::Meta::TypeConstraint::Class object. $test_name is the description of the test. If not given, one will be provided. %options control optional behaviors. Its keys can be the following... coerce If true, coercion will be used when performing the type check. If a code ref is given, it will be run and passed in the coerced value for additional testing. type_isa $value, "Some::Class", "coerce to Some::Class", coerce => sub { isa_ok $_[0], "Some::Class"; is $_[0]->value, $value; }; type_does type_does($value, $role); type_does($value, $role, $test_name); type_does($value, $role, $test_name, %options); Tests that the $value does the $role. Works like "type_isa", but for roles instead of classes and types. The $value must have consumed the given $role. type_isnt type_doesnt The opposites of "type_isa" and "type_does". They take the same arguments and options. Checks that the value is *not* of the given type or role.
