testAction（）函数在CakePHP测试中的debug（）上返回null [英] testAction() function returns null on debug() in CakePhp testing

问题描述

我试图学习如何在CakePhp中使用单元测试，我试图写一个控制器测试。我读了关于testAction（）和debug（）函数，但它不工作，我的意思是，测试方法通过，但是debug（）返回null（因为testAction）

I was trying to learn how to use unit testing in CakePhp, I'm trying to write a controller test. I read about testAction() and debug() function, but It doesn't work for me, I mean, the test method passes, but the debug() returns null (because testAction does)

这是我的代码：

<?php
App::uses('Controller', 'Controller');
App::uses('View', 'View');
App::uses('PostsController', 'Controller');

class PostsControllerTest extends ControllerTestCase {
    public function setUp() {
       parent::setUp();
       $Controller = new Controller();
       $View = new View($Controller);
       $this->Posts = new PostsController($View);
    }

    public function testIndex() {
          $result = $this->testAction('Posts/Index');
        debug($result);        

    }
}

帖子/索引控制器返回列表的所有帖子存储在DB中。

Posts/index controller returns a list of all posts stored in the DB.

推荐答案

我假设您使用CakePHP 2。

I'm assuming you're using CakePHP 2.

$ this-> testAction（）可以返回几个不同的结果，具体取决于您给出的选项。

$this->testAction() can return a few different results, depending on the options you give it.

例如，如果将 return 选项设置为 vars ，则 testAction 方法将返回在测试操作中设置的vars数组：

For example, if you set the return option to vars, the testAction() method will return an array of the vars that have been set in the tested action:

public function testIndex() {
    $result = $this->testAction('/posts/index', array('return' => 'vars'));
    debug($result);
}

在此示例中，调试数据应该是vars数组设置在 / posts / index 操作中。

In this example, the debug data should be an array of the vars that you set in the /posts/index action.

CakePHP文档描述了您可以返回的可能结果： http://book.cakephp.org/ 2.0 / en / development / testing.html＃selecting-the-return-type

The CakePHP documentation describes the possible results that you can have returned here: http://book.cakephp.org/2.0/en/development/testing.html#choosing-the-return-type

请注意，默认选项 result ，为您提供控制器操作返回的值。对于大多数控制器操作，这将是 null ，所以在你的例子中你得到 null 的事实是预期。

Note that the default option, result, gives you the value that your controller action returns. For most controller actions this will be null, so the fact that you're getting null in your example is to be expected.
