Symfony 2 +学说2 + Phpunit 3.5:闭合序列化异常
题
我试图在Google上找到有关此事的信息,但什么都没有。我有一个从webtestcase继承的测试柜类,其中一些方法我想在我的所有单元/功能测试中使用:
<?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,我的单位测试:
<?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 );
}
}
它以前是在工作,但是突然,在我更新供应商(包括学说)之后,它开始引发这个例外:
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:
#0 [internal function]: PDO->__sleep()
#1 -(32): serialize(Array)
#2 -(113): __phpunit_run_isolated_test()

Next exception 'Exception' with message 'Serialization of 'Closure' is not allowed' in -:0
Stack trace:
#0 -(0): serialize()
#1 -(113): __phpunit_run_isolated_test()
#2 {main}

我发现问题来自固定装置。如果我删除加载固定装置的代码,则可以使用。
有人知道我的代码中可能出了什么问题吗?这是加载固定装置的最佳方法吗?
谢谢!
解决方案
从技术上讲与您的问题无关。但是,使用PHPUNIT时,我非常困难地尝试解决“闭合'的序列化”问题,而这个问题是Google最佳结果。
问题源于以下事实:Phpunit序列化系统中的所有$ Globals在测试运行时都必须支持它们。然后在测试完成后将它们还原。
但是,如果您的全球空间中有任何关闭,则会引起问题。有两种解决方法。
您可以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引起了问题(在var_dump中寻找lambda($ globals),则可以将问题变量放黑名单。
class MyTest extends PHPUnit_Framework_TestCase
{
protected $backupGlobalsBlacklist = array('application');
// ...
}
其他提示
您也可以尝试。
<phpunit backupGlobals="false">
<testsuites>
<testsuite name="Test">
<directory>.</directory>
</testsuite>
</testsuites>
</phpunit>
