Hi,

I've got a class that calls methods like $self->method, which I'd like to write tests for. Because the internal method call might have state data I don't want to setup, I'd like to mock this method. For this, I thought I could use Test::MockObject::Extends.

Unfortunately, it looks like T::MO::E doesn't mock these methods. As an example, look at this class: 
use strict;
use warnings;

package Foo;

sub new {
    my $class = shift;
    
    return bless {}, $class;
}

sub bar {
    my $self = shift;
    
    $self->baz;
    
    return 1;
}

sub baz {
    die;
}

1;

(This has to be in a separate file if you want to test this, because T::MO::E tries to 'use' the module when you call new()).

The test script below should be ok, but instead it dies (when bar() internally calls baz(), which I've attempted to mock): 
use strict;
use warnings;

use Foo;

use Test::MockObject::Extends;

my $foo = Foo->new();
my $mock_foo = Test::MockObject::Extends->new( $foo );

$mock_foo->mock('baz',sub { 1 });

$mock_foo->bar;

Am I totally missing the point of Test::MockObject::Extends? Is my code untestable and in need of refactoring (probably, but not necessarily practical)? Any other suggestions?

Thanks.
