如何在PHPUnit测试用例中使用服务器变量? [英] How to use server variables in PHPUnit Test cases?

问题描述

我正在使用PHPUnit测试用例测试模块.一切正常，但是当我使用$_SERVER['REMOTE_ADDR']时，它会导致致命错误并停止执行.

I am testing modules using PHPUnit Test cases. All the things working fine but when i use $_SERVER['REMOTE_ADDR'] it gives fatal error and stops execution.

CategoryControllerTest.php

<?php
namespace ProductBundle\Controller\Tests\Controller;
use Symfony\Bundle\FrameworkBundle\Test\WebTestCase;
class CategoryControllerTest extends WebTestCase {

     protected function setUp() {
        static::$kernel = static::createKernel();
        static::$kernel->boot();
        $this->container = static::$kernel->getContainer();
        $this->em = static::$kernel->getContainer()->get('doctrine')->getManager();
    }

    public function testCategory() {
        $ip_address = $_SERVER['REMOTE_ADDR'];
        $client = static::createClient(
          array(), array('HTTP_HOST' => static::$kernel->getContainer()->getParameter('test_http_host')
        ));

        $crawler = $client->request('POST', '/category/new');
        $client->enableProfiler();

        $this->assertEquals('ProductBundle\Controller\CategoryController::addAction', $client->getRequest()->attributes->get('_controller'));
        $form = $crawler->selectButton('new_category')->form();
        $form['category[name]'] = "Electronics";
        $form['category[id]']   = "For US";
        $form['category[ip]']   = $ip_address;
        $client->submit($form);

        $this->assertTrue($client->getResponse()->isRedirect('/category/new')); // check if redirecting properly
        $client->followRedirect();
        $this->assertEquals(1, $crawler->filter('html:contains("Category Created Successfully.")')->count());
    }
}

错误

有1个错误:

1)ProductBundle \ Tests \ Controller \ CategoryControllerTest :: testCategory 未定义的索引:REMOTE_ADDR

1) ProductBundle\Tests\Controller\CategoryControllerTest::testCategory Undefined index: REMOTE_ADDR

我尝试将其添加到setUp()函数中，但效果不佳.

I have tried to add it in setUp() function but it's not working as well.

推荐答案

创建返回IP地址并在测试用例中模拟该服务的服务.

Create service which returns ip address and mock the service in test case.

在此处，将控制器和服务创建为 UserIpAddress . get()将返回用户的IP地址.

Here, create controller and service as UserIpAddress. get() will return ip address of user.

service.yml

UserIpAddress:
    class: AppBundle\Controller\UserIpAddressController
    arguments: 
    container: "@service_container"  

UserIpAddressController.php

class UserIpAddressController
{
  public function get()
  {
    return $_SERVER['REMOTE_ADDR'];
  }
}

创建"UserIpAddress"服务的模拟.它将覆盖现有服务.使用"UserIpAddress"服务获取您项目中的IP地址.

Create mock of "UserIpAddress" service. It will override existing service. Use 'UserIpAddress' service to get ip address in your project.

CategoryControllerTest.php

$UserIpAddress = $this->getMockBuilder('UserIpAddress')
    ->disableOriginalConstructor()
    ->getMock();

$UserIpAddress->expects($this->once())
  ->method('get')
  ->willReturn('192.161.1.1'); // Set ip address whatever you want to use

现在，使用$UserIpAddress->get();
