NAME

Test::Interface - Test if a class implements an interface

SYNOPSIS

To create an Interface:

package MyProject::Foo::Interface;

use Role::MethodReturns;

around my_foo_method => class_method ( Str, $foo, Int $bar ) {
    returns_object_does_interface( 'MyProject::Bar::Interface'(
        $original->( $class => ( $foo, $bar ) )
}

And in some implementation:

package MyProject::Foo

sub my_foo_method { ... }

...

And in tests:

use Test::Most;
use Test::Interface;

interface_ok('MyProject::Foo', 'MyProject::Foo::Interface',
    "huray! We implemented all methods!!"

done_testing();
