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();

DESCRIPTION

Test if a class implements an interface, using Role::Inspector

SEE ALSO

Role::MethodReturns

A bad attempt for writing readable interfaces.

Role::Inspector

Introspection for roles, providing does_role.

Role::Tiny

A minimalist role composition tool.

Test::Role

Which works fine for objects, but not for classes.
