如何在Laravel 4中添加Auth作为控制器依赖项进行测试

Question

I'm starting out with some TDD in Laravel 4. While I understand the basics of dependency injection, I can't seem to get my head around how to mock the Auth functionality. Below is my current user controller with just the index method and it's applicable test. The current setup keeps throwing me errors when I run phpunit, namely "undefined index" errors for Auth. Is there a better way of doing this?

My Controller:

class UserController extends \BaseController {

    /**
     * User instance
     * 
     * @var User
     */
    protected $user;

    /**
     * The master layout that View's will be built upon.
     * 
     * @var string
     */
    protected $layout = 'layout.user-master';

    /**
     * Constructor
     * 
     * @param User $user
     * @param View $view
     */
    public function __construct(User $user) 
    {
        $this->user = $user;

        // Filters
        $this->beforeFilter('csrf', array('on' => 'post'));
        $this->beforeFilter('auth', array('except' => array('create', 'store')));
    }

    /**
     * Display a listing of the user.
     *
     * @return Response
     */
    public function index()
    {
        $id = Auth::user()->id;

        $user = $this->user->find($id);

        $this->layout->content = View::make('user.index', compact('user'));
    }
}

User Controller Test

<?php

use \Mockery;

class UserControllerTest extends TestCase {

    public function __construct()
    {
        // Mock an Eloquent User Model instance
        $this->mock = Mockery::mock('Eloquent', 'User');    
    }

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

    public function testIndex()
    {
        Auth::shouldReceive('user')->once()->andReturn(Mockery::any());

        $this->mock
                ->shouldReceive('find')
                ->once()
                ->with(Mockery::any())
                ->andReturn('foo');

        $this->app->instance('User', $this->mock);

        $this->call('GET', 'user');

        $this->assertViewHas('user');
    }

}

I've found the solution to this issue.

All I had to do is call the be() method in my test to set the currently logged in user.

$this->be(User::find(1));
