Test::TypeConstraints - testing whether some value is valid as (Moose|Mouse)::Meta::TypeConstraint

use Test::TypeConstraints qw(type_isa);

type_isa($got, "ArrayRef[Int]", "type should be ArrayRef[Int]");

Test::TypeConstraints is for testing whether some value is valid as (Moose|Mouse)::Meta::TypeConstraint.

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...

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($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.

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.
