Partial moking not working [Laravel 5]

I try to mock just one function form reposiory but I get this error:

Method Mockery_1_App_Repositories_CommentInterface::updateAccepted() does not exist on this mock object

But I don't want the updateAccepted method be mocked...

Here is my test:

public function testUpdateAcceptedApi(){
        $user = new User(array('name' => 'John','id'=>1));
        $this->be($user);

        $mock = m::mock('App\Repositories\UserAuthInterface');
        $mock->shouldReceive('hasRoleClient')->once()->andReturn(true);
        App::instance('App\Repositories\UserAuthInterface', $mock);

         $mock1 = m::mock('App\Repositories\CommentInterface');
        $mock1->shouldReceive('returnUserProject')->once()->andReturn(2);
        App::instance('App\Repositories\CommentInterface', $mock1);

        $response = $this->call('POST', 'api/comment/accepted', array(
            'accepted' => 1,
            'id'       => 1
        ));

        echo "SUCCESFUL UPDATE ACCEPT REQUEST\n";
        $this->assertEquals('Success', $response->getContent());
    }

Any idea how to not mock updateAccepted method inside rep?
