我尝试在 Google 上查找有关此内容的信息,但一无所获。我有一个继承自 WebTestCase 的 TestCase 类,其中包含一些我想在所有单元/功能测试中使用的方法:
<?php
namespace Application\FaxServerBundle\Test;
use Symfony\Bundle\FrameworkBundle\Test\WebTestCase;
use Doctrine\Common\DataFixtures\Loader;
use Doctrine\Common\DataFixtures\Executor\ORMExecutor;
use Doctrine\Common\DataFixtures\Purger\ORMPurger;
use Application\FaxServerBundle\DataFixtures\ORM\NetworkConfigurationData;
class TestCase extends WebTestCase
{
protected $kernel;
public function setUp()
{
parent::setUp();
}
public function getEm()
{
return $this->getService( 'doctrine.orm.entity_manager' );
}
public function getNetworkConfigurationRepository()
{
return $this->getEm()->getRepository( 'Application\FaxServerBundle\Entity\NetworkConfiguration' );
}
public function loadNetworkConfigurationFixtures()
{
$loader = new Loader();
$loader->addFixture( new NetworkConfigurationData() );
$this->loadFixtures( $loader );
}
public function loadFixtures( $loader )
{
$purger = new ORMPurger();
$executor = new ORMExecutor( $this->getEm(), $purger );
$executor->execute( $loader->getFixtures() );
}
protected function getService( $name, $kernel = null )
{
return $this->getBootedKernel()->getContainer()->get( $name );
}
protected function hasService( $name, $kernel = null )
{
return $this->getBootedKernel()->getContainer()->has( $name );
}
protected function getBootedKernel()
{
$this->kernel = $this->createKernel();
if ( !$this->kernel->isBooted() )
{
$this->kernel->boot();
}
return $this->kernel;
}
public function generateUrl( $client, $route, $parameters = array() )
{
return $client->getContainer()->get( 'router' )->generate( $route, $parameters );
}
}
然后,我的单元测试:
<?php
namespace Application\FaxServerBundle\Tests\Entity;
use Doctrine\ORM\AbstractQuery;
use Application\FaxServerBundle\Entity;
use Application\FaxServerBundle\Test\TestCase;
class NetworkConfigurationRepositoryTest extends TestCase
{
public function setUp()
{
parent::setUp();
$this->loadNetworkConfigurationFixtures();
}
public function testGetConfiguration()
{
$config = $this->getNetworkConfigurationRepository()->getConfigurationArray();
$this->assertInternalType( 'array', $config );
$this->assertEquals( 6, count( $config ) );
$this->assertArrayHasKey( 'id', $config );
$this->assertArrayHasKey( 'ip', $config );
$this->assertArrayHasKey( 'gateway', $config );
$this->assertArrayHasKey( 'subnetMask', $config );
$this->assertArrayHasKey( 'primaryDns', $config );
$this->assertArrayHasKey( 'secondaryDns', $config );
}
public function testGetConfigurationObject()
{
$config = $this->getNetworkConfigurationRepository()->getConfigurationObject();
$this->assertInternalType( 'object', $config );
}
public function testGetConfigurationArray()
{
$config = $this->getNetworkConfigurationRepository()->getConfigurationArray();
$this->assertInternalType( 'array', $config );
}
}
它之前可以工作,但是,突然,在我更新我的供应商(包括 Doctrine )后,它开始抛出此异常:
3) Application\FaxServerBundle\Tests\Entity\NetworkConfigurationRepositoryTest::testGetConfigurationArray
RuntimeException: PHP Fatal error: Uncaught exception 'PDOException' with message 'You cannot serialize or unserialize PDO instances' in -:32
Stack trace:

Stack trace:

我发现问题出在夹具加载上。如果我删除加载灯具的代码,它就可以工作。
有谁知道我的代码可能有什么问题?这是加载装置的最佳方式吗?
谢谢!
最佳答案
技术上与您的问题无关。然而,我在使用 PHPUnit 时尝试解决“不允许‘闭包’序列化”问题非常困难,而这个问题是 Google 的最高结果。
问题源于 PHPUnit 序列化系统中的所有 $GLOBALS 以便在测试运行时对它们进行必要的备份。然后在测试完成后恢复它们。
但是,如果您的 GLOBAL 空间中有任何关闭,就会导致问题。有两种方法可以解决。
您可以通过使用注释完全禁用全局备份过程。
/**
* @backupGlobals disabled
*/
class MyTest extends PHPUnit_Framework_TestCase
{
// ...
}
或者,如果您知道哪个变量导致了问题(在 var_dump($GLOBALS) 中查找 lambda),则可以将问题变量列入黑名单。
class MyTest extends PHPUnit_Framework_TestCase
{
protected $backupGlobalsBlacklist = array('application');
// ...
}
关于Symfony 2 + Doctrine 2 + PHPUnit 3.5 : Serialization of closure exception,我们在Stack Overflow上找到一个类似的问题: https://stackoverflow.com/questions/4366592/
