php - 模拟静态 Eloquent 模型方法，包括 find()

Question

我一直在关注一般的 Mockery 和 PHP-Unit 教程 - 包括 Jeffrey Way 介绍的使用 PHP-Unit 和 Mockery 测试 Laravel。然而，对于这个应用程序——我们可以接受对 Eloquent 的依赖，而不是创建一个存储库类。

我们能够很好地模拟 Widget 模型的实例方法。但是，我们正在使用 Route:model 绑定(bind)，我承认我不确定在测试 Controller 的 show($widget) 方法时如何模拟模型的 find() 方法。

我读过 https://github.com/padraic/mockery/wiki#mocking-public-static-methods文档，并看到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发挥作用。

这是 routes.php...

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

这是(缩短的) Controller ...

<?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;
    }

    /**

    public function index()
    {
        // Title
        $title = Lang::get('widget/title.widget_management');

        // Show the page
        return View::make('widget/index', compact('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.

    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。

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

    }
}

testShow 方法的错误是:调用未定义的方法 Widget::find()

想法？

好的 - 删除了路由模型绑定(bind)，并向模拟模型的 View 返回了一个对象。
