# 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. # AUTHOR Keiji Yoshimi # THANKS TO - schwern - gfx - tokuhirom # SEE ALSO [Mouse::Util::TypeConstraints](http://search.cpan.org/perldoc?Mouse::Util::TypeConstraints), [Moose::Util::TypeConstraints](http://search.cpan.org/perldoc?Moose::Util::TypeConstraints) # LICENSE This library is free software; you can redistribute it and/or modify it under the same terms as Perl itself.
