Doctrine2.2（使用内存的sqlite）使用OrmTestCase和phpUnit疑难解答

我目前正在尝试使用phpUnit测试我的doctrine2.2对象，我正在使用可以找到的doctrine扩展

这是我的所有phpUnit测试类都扩展的基类

<?php
use DoctrineExtensions\PHPUnit\Event\EntityManagerEventArgs,
    DoctrineExtensions\PHPUnit\OrmTestCase,
    Doctrine\ORM\Tools\SchemaTool,
    Doctrine\Common\EventManager,
    Doctrine\ORM\Tools\Setup,
    Doctrine\ORM\EntityManager;

class SchemaSetupListener {
    public function preTestSetUp(EntityManagerEventArgs $eventArgs) {
        $em = $eventArgs->getEntityManager();
        $schemaTool = new SchemaTool($em);
        $cmf = $em->getMetadataFactory();
        $classes = $cmf->getAllMetadata();
        $schemaTool->dropDatabase();
        $schemaTool->createSchema($classes);
    }
}

class EntityFunctionalTest extends OrmTestCase {

    protected function createEntityManager() {
        $config = Setup::createXMLMetadataConfiguration(array(DIR_XML_SCHEMA), true); // dev mode true
        $conn = array('driver' => 'pdo_sqlite', 'path' =>  DIR_TEST_SUITE_ROOT . 'test.db');
        $conn = array('driver' => 'pdo_sqlite', 'memory' => true);
        $eventManager = new EventManager();
        $eventManager->addEventListener(array("preTestSetUp"), new SchemaSetupListener());
        return Doctrine\ORM\EntityManager::create( $conn, $config, $eventManager);
    }

    protected function getDataSet() {
        return $this->createFlatXmlDataSet(DIR_XML_TEST_DATA . 'db.boot.strap.test.flat.xml');
    }

    protected function tearDown(){
        $entityManager = $this->getEntityManager();
        $entityManager->flush();
        $entityManager->getConnection()->getConfiguration()->setSQLLogger(null);;
        $entityManager->close();
    }

    public function getSystemUser(){
        return $this->getEntityManager()->createQuery('select u from User u where u.id = 1')->getSingleResult();
    }
}

?>

当我取消对该行的注释并尝试使用内存中的slqlite数据库运行测试时，只有第一个测试函数从getDataSet（）方法获取数据（当我使用sqlite数据库运行此函数时，一切正常）

为什么getDataSet（）方法只对第一个测试方法有效？

以下是在命令行中运行测试的me的输出：

我遇到了同样的问题，解决方案是在测试之间共享实体管理器：

protected static $em = null;

public static function setUpBeforeClass()
{
    $isDevMode = true;
    $config = Setup::createAnnotationMetadataConfiguration(array(__DIR__."/../src"), $isDevMode, null, null, false);

    $connectionOptions = array('driver' => 'pdo_sqlite', 'memory' => true);

    // obtaining the entity manager
    self::$em =  EntityManager::create($connectionOptions, $config);

    $schemaTool = new SchemaTool(self::$em);

    $cmf = self::$em->getMetadataFactory();
    $classes = $cmf->getAllMetadata();

    $schemaTool->dropDatabase();
    $schemaTool->createSchema($classes);

}

public static function tearDownAfterClass()
{
    self::$em = NULL;
}

protected function createEntityManager()
{


    return self::$em;
}

除了@Zedenek Machek所说的： 从测试松散耦合的角度来看，应避免共享夹具：

在测试之间共享夹具会降低测试的价值，这一点再怎么强调也不为过。潜在的设计问题是对象不是松散耦合的。通过解决底层设计问题，然后使用存根编写测试（参见第9章），您将获得比在运行时创建测试之间的依赖关系并忽略改进设计的机会更好的结果

看

protected static $em = null;

public static function setUpBeforeClass()
{
    $isDevMode = true;
    $config = Setup::createAnnotationMetadataConfiguration(array(__DIR__."/../src"), $isDevMode, null, null, false);

    $connectionOptions = array('driver' => 'pdo_sqlite', 'memory' => true);

    // obtaining the entity manager
    self::$em =  EntityManager::create($connectionOptions, $config);

    $schemaTool = new SchemaTool(self::$em);

    $cmf = self::$em->getMetadataFactory();
    $classes = $cmf->getAllMetadata();

    $schemaTool->dropDatabase();
    $schemaTool->createSchema($classes);

}

public static function tearDownAfterClass()
{
    self::$em = NULL;
}

protected function createEntityManager()
{


    return self::$em;
}
