Doctrine2：PreUpdate的单元测试

我正在尝试对我的Doctrine2实体中的生命周期事件的结果进行单元测试 . PrePersist工作，但不是PreUpdate：

// in Entity class:

/**
 * @ORM\PrePersist
 * @ORM\PreUpdate
 */
public function setEndIpForSingle()
{
    if (isset($this->startIp) && !isset($this->endIp)) {
        $this->setEndIp($this->startIp);
    }
}


// in test:

class IpRangeTest extends OrmTestCase
{
    protected $_em;

    protected function setUp()
    {
        $reader = new AnnotationReader();
        $reader->setIgnoreNotImportedAnnotations(true);
        $reader->setEnableParsePhpImports(true);

        $metadataDriver = new AnnotationDriver(
            $reader, 'Yitznewton\\FreermsBundle\\Entity'
        );

        $this->_em = $this->_getTestEntityManager();

        $this->_em->getConfiguration()
            ->setMetadataDriverImpl($metadataDriver);

        $this->_em->getConfiguration()->setEntityNamespaces(array(
            'YitznewtonFreermsBundle' => 'Yitznewton\\FreermsBundle\\Entity'));
    }

    public function testSetEndIpForSingle_UpdateSingle_SetsEndIp()
    {
        $ipRange = new IpRange();
        $ipRange->setStartIp('192.245.1.1');
        $ipRange->setEndIp('192.245.1.2');

        $this->_em->persist($ipRange);
        $this->_em->flush();  // this is line 68

        $ipRange->setStartIp('192.245.2.1');
        $ipRange->setEndIp(null);

        $this->_em->flush();

        $this->assertEquals('192.245.2.1', $ipRange->getEndIp(),
            'IpRange::endIp set on update of single IP address');
    }

结果：

PHP致命错误：在第98行的/var/www/symfony/vendor/doctrine-dbal/lib/Doctrine/DBAL/Statement.php中的非对象上调用成员函数bindValue（）PHP堆栈跟踪：PHP 1 . （）/ usr / bin / phpunit：0 PHP 2.

任何见解？谢谢！
