unit-testing - zf2 phpunit 控制器依赖

Question

我正在对我的控制器进行单元测试IndexController（使用http://framework.zend.com/manual/2.1/en/user-guide/modules.html教程）。

我的 IndexController 有一个依赖项：Translator $translator.

<?php
// module/Application/src/Application/Controller/IndexController.php

namespace Application\Controller;

use Zend\Mvc\Controller\AbstractActionController;
use Zend\View\Model\ViewModel;
use Zend\I18n\Translator\Translator;

class IndexController extends AbstractActionController
{
    protected $translator;

    public function __construct(Translator $translator)
    {
        $this->translator = $translator;
    }

    public function indexAction()
    {                
        $steeringWheelMapper = $this->getServiceLocator()->get('SupplierName\Mapper\SteeringWheel');
        $carBrandList = $steeringWheelMapper ->fetchCarBrandList();
        return new ViewModel();
    }
}

我的单元测试设置：

• 模块
  • 应用
    • 测试
      • 应用测试
        • 控制器
          • 索引控制器测试.php
      • 引导程序.php
      • phpunit.xml.dist
      • TestConfig.php.dist

测试现在给出以下错误： Argument 1 passed to Application\Controller\IndexController::__construct() must be an instance of Zend\I18n\Translator\Translator, none given。这里没什么奇怪的，但我找不到在哪里添加翻译器对象..

我应该在哪里添加翻译器对象？

Answer 1

在你的 setUp 方法中注入它

protected function setUp()
{
    // ...
    $translator = new \Zend\I18n\Translator;
    $this->controller = new IndexController($translator);
    // ....
}
