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.
