php - $this->dispatch ('/' ) 在 zend 测试中意味着什么

Question

我正在为 zend 项目编写单元测试， 我想知道

<?php

    class IndexControllerTest extends ControllerTestCase
    {

        public function testHomePage() {
            $this->dispatch('/');

        }
    }

ControllerTestcase.php 扩展了 Zend/Test/PHPUnit/ControllerTestCase.php

<?php
    require_once 'Zend/Application.php';
    require_once 'Zend/Test/PHPUnit/ControllerTestCase.php';

    class ControllerTestCase 
        extends Zend_Test_PHPUnit_ControllerTestCase 
    {
        protected $application;

        public function setUp() {
            $this->bootstrap = array($this,'appBootstrap');
            parent::setUp();

        }

        public function appBootstrap() {
            $this->application = 
                new Zend_Application(APPLICATION_ENV,
                                     APPLICATION_PATH.'/configs/application.ini');

            $this->application->bootstrap();


        }
    }

$this->dispatch('/'); 的作用是什么方法？这是否意味着将请求转发到应用程序的根目录？

Answer 1

从注释到此方法:

 * Dispatch the MVC
 *
 * If a URL is provided, sets it as the request URI in the request object.
 * Then sets test case request and response objects in front controller,
 * disables throwing exceptions, and disables returning the response.
 * Finally, dispatches the front controller.
