Mocking PasswordBroker::remind() with PHPUnit for Testing

I am using Laravel 4 with phpunit 4.5.0 and have some code that looks like:

public function someFunction(){

    $cred = Input::only(
            'email', 'password'
    );

    $response = Password::reset($cred, function($user, $password){
             //do some stuff
    });

}

I want to test it; however, I can't seem to get the PasswordBroker::reset mocked. I keep getting the error.

BadMethodCallException : Method Mockery_1_Illuminate_Auth_Reminders_PasswordBroker::remind() does not exist on this mock object

My test looks like:

<?php

protected $PasswordBrokerMock;
protected $ControllerTest;

class ControllerTest extends TestCase
{  
    public function setUp()
    {
        parent::setUp();

        $this->PasswordBrokerMock = Mockery::mock('Illuminate\Auth\Reminders\PasswordBroker');

        $this->assertInstanceOf('Illuminate\Auth\Reminders\PasswordBroker', $this->PasswordBrokerMock);

    }

        public function tearDown()
    {
        Mockery::close();
    }

    public function testFunction(){

        Password::shouldReceive('reset')->andReturn(true);
        $this->PasswordBrokerMock->shouldReceive('remind')->andReturn('something');

        $this->route('get', 'page', array('identifier' => 'identifier'), array('email' => 'email', 'password' => 'password'));

        $this->ControllerMock = new Controller;
        $this->ControllerMock->someFunction();

    }
}
