【问题描述】：

我一直在关注一般的 Mockery 和 php-Unit 教程 - 包括 Jeffrey Way 对使用 PHP-Unit 和 Mockery 测试 Laravel 的介绍。然而，对于这个应用程序 - 我们对 Eloquent 的依赖很好，并且宁愿不创建存储库类。

我们能够很好地模拟 Widget 模型的实例方法。但是，我们使用的是 Route:model 绑定，我承认在测试控制器的 show($widget) 方法时，我不确定如何模拟模型的 find() 方法。

我已经阅读了https://github.com/padraic/mockery/wiki#mocking-public-static-methods 文档，发现可以在要模拟的类前面放置一个“别名”前缀。但我似乎也无法让它工作。

这里是 routes.php...

Route::model('widgets', 'Widget');
Route::resource('widgets', 'WidgetController');

这是（缩短的）控制器...

<?php
/*
|--------------------------------------------------------------------------
| Widget Controller
|--------------------------------------------------------------------------
|
| An example controller that uses the pre-baked RESTful resource controller
| actions for index, create, store, show, edit, update, destroy, as well as a
| delete method to show the record before deletion.
|
| See routes.php  ->
| Route::resource('widget', 'WidgetController');
| Route::get('widget/widget/delete', 'WidgetController@delete');
|
*/

class WidgetController extends BaseController

    /**
     * Widget Model
     * @var Widget
     */
    protected $widget;

    /**
     * Inject the model.
     * @param Widget $widget
     */
    public function __construct(Widget $widget)
    
        parent::__construct();
        $this->widget = $widget;
    

    /**
     * Display a listing of the resource.
     *
     * See public function data() below for the data source for the list,
     * and the view/widget/index.blade.php for the jQuery script that makes
     * the Ajax request.
     *
     * @return Response
     */
    public function index()
    
        // Title
        $title = Lang::get('widget/title.widget_management');

        // Show the page
        return View::make('widget/index', compact('title'));
    

    /**
     * Show a single widget details page.
     *
     * @return View
     */
    public function show($widget)
    
        // Title
        $title = Lang::get('widget/title.widget_show');

        // Show the page
        return View::make('widget/show', compact('widget', 'title'));
    

    /**
     * Show the form for creating a new resource.
     *
     * @return Response
     */
    public function create()
    
        // Title
        $title = Lang::get('widget/title.create_a_new_widget');

        // Show the page
        return View::make('widget/create', compact('title'));
    

    /**
     * Store a newly created resource in storage.
     *
     * @return Response
     */
    public function store()
    
        // Validate the inputs
        $rules = array(
            'name'=> 'required|alpha_dash|unique:widgets,name',
            'description'=> 'required'
            );

        // Validate the inputs
        $validator = Validator::make(Input::all(), $rules);

        // Check if the form validates with success
        if ($validator->passes()) 
            // Get the inputs, with some exceptions
            $inputs = Input::except('csrf_token');

            $this->widget->name = $inputs['name'];
            $this->widget->description = $inputs['description'];
            $this->widget->save($rules);

            if ($this->widget->id) 
                // Redirect to the new widget page
                return Redirect::to('widgets')->with('success', Lang::get('widget/messages.create.success'));

             else 
                // Redirect to the widget create page
                //var_dump($this->widget);
                return Redirect::to('widgets/create')->with('error', Lang::get('widget/messages.create.error'));
            
         else 
            // Form validation failed
            return Redirect::to('widgets/create')->withInput()->withErrors($validator);
        
    

这是测试夹具。

# /app/tests/controllers/WidgetControllerTest.php

class WidgetControllerTest extends TestCase

    public function __Construct()
    
        $this->mock = Mockery::mock('Eloquent', 'Widget');
    

    public function setUp()
    
        parent::setUp();

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

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

    /**
     * Index
     */
    public function testIndex()
    
        $this->call('GET', 'widgets');

        $this->assertTrue($this->client->getResponse()->isOk());
        $this->assertViewHas('title');
    

    /**
     * Show
     */
    public function testShow()
    
        //$this->mock->shouldReceive('find')->with(1)->once()->andReturn(array('id'=>1));

        $this->mock
        ->shouldReceive('find')
        ->once()
        ->andSet('id', 1);

        //$this->call('GET', 'widgets/1');
        $this->action('GET', 'WidgetController@show', array(
            'widgets' => 1
            ));

        $this->assertTrue($this->client->getResponse()->isOk());
    

    /**
     * Create
     */
    public function testCreate()
    
        $crawler = $this->client->request('GET', 'widgets/create');

        $this->assertTrue($this->client->getResponse()->isOk());
        $this->assertViewHas('title');
        $this->assertCount(1, $crawler->filter('h3:contains("Create a New Widget")'));

    

    /**
     * Store Success
     */
    public function testStoreSuccess()
    
        $this->mock
        ->shouldReceive('save')
        ->once()
        ->andSet('id', 1);

        $this->call('POST', 'widgets', array(
            'name' => 'Fu-Widget',
            'description' => 'Widget description'
            ));

        $this->assertRedirectedToRoute('widgets.index');
    

    /**
     * Store Fail
     */
    public function testStoreFail()
    

        $this->call('POST', 'widgets', array(
            'name' => '',
            'description' => ''
            ));

        $this->assertRedirectedToRoute('widgets.create');
        $this->assertSessionHasErrors(['name']);

    

testShow方法报错：Call to undefined method Widget::find()

想法？

【参考方案1】：

好的 - 移除了 Route 模型绑定，并将一个对象返回给模拟模型的视图。
