Symfony/PHPUnit模拟服务 [英] Symfony/PHPUnit mock services

问题描述

我正在为带有PHPUnit的Symfony编写功能测试，而我的模拟无法正常工作.我可能会误解了它们的工作原理.

I'm writing functional tests for Symfony w/ PHPUnit, and my mocks aren't working. It's possible I misunderstood how they work though.

在单元测试的setUp()方法中，我有以下代码:

In my unit test's setUp() method I have this code:

...
// Create a stub
$stub = $this->getMockBuilder('\\ApiBundle\\Util\\WordPressBridge')
    ->disableOriginalConstructor()
    ->getMock();

// Configure the stub.
$user = new WordPressUser();
$user->setUsername('dummy');
$stub->expects($this->any())
     ->method('checkCredentials')
     ->will($this->returnValue(true));
$stub->expects($this->any())
     ->method('getUser')
     ->will($this->returnValue($user));
...

在我的Symfony应用程序中，我定义了一个服务:

In my Symfony application, I have a service defined:

services:
    api.wp_bridge:
        class: ApiBundle\Util\WordPressBridge
        arguments: [@service_container]

据我了解，该模拟应该替换真正的WordPressBridge，但这不是正在发生的事情.我的原件仍在使用中.我想念什么吗?

It's my understanding that the mock should be replace the real WordPressBridge, but that isn't what's happening. My original is still being used. Am I missing something?

基本上，您必须以某种方式在Symfony容器中替换服务.

Basically you have to replace your service somehow in the Symfony Container.

如果您进行功能测试"，则可能应该为测试" env创建测试虚拟"服务，这将覆盖原始服务.您可以执行以下操作:

If you doing "functional testing" then probably you should create test "dummy" service for "test" env which will overwrote original one. You can do something like that:

在 src/YourBundle/Resources/config/services.yml

services:
    api.wp_bridge:
        class: %api.wp_bridge.class%
        arguments: [@service_container]

在 app/config/config.yml

parameters:
    api.wp_bridge.class: "ApiBundle\Util\WordPressBridge"

在 app/config/config_test.yml

parameters:
    api.wp_bridge.class: "ApiBundle\Util\TestWordPressBridge"

然后功能测试将使用"ApiBundle \ Util \ TestWordPressBridge"-因为它是在测试" env中执行的.

Then functional test will use "ApiBundle\Util\TestWordPressBridge" - cause it is executed in "test" env.

您可以尝试模拟容器并将其传递给测试内核，但是如果没有其他模拟库(在纯PHPUnit中)，这可能会很痛苦.

You can try to mock container and pass it to test kernel but this can be painfull without some other mocking lib (in pure PHPUnit).

我个人使用 phpspec2 进行单元"测试，其中模拟很容易:)和一些接受条件" 我正在使用 behat 和

Personally I am using phpspec2 for "unit" testing where mocking is just easy :) and for some "acceptance criteria" stuff I am using behat and mink
