Symfony4:Doctrine2工作但PHPUnit测试中没有连接(内核启动)

Question

Symfony4中的奇怪问题:Doctrine有效,我可以使用验证模式,创建数据库等php bin/console doctrine:schema:create.但我的PHPUnit测试没有连接.通过运行./bin/phpunit我得到SQLSTATE[HY000] [2002] No such file or directory例外.

我按照文档中有关启动内核的步骤进行操作:http: //symfony.com/doc/current/testing/doctrine.html

我的代码:

class PersistingResultTest extends KernelTestCase
{
    protected $em;

    protected function setUp()
    {
        $kernel = self::bootKernel();

        $this->em = $kernel->getContainer()
            ->get('doctrine')
            ->getManager();
    }

    public function testPersistingLogFile()
    {
        // Just a simple schema command to test connection
        $tool = new SchemaTool($this->em);
        $tool->createSchema($this->em->getMetadataFactory()->getAllMetadata());
    }


   protected function tearDown()
    {
        parent::tearDown();

        $this->em->close();
        $this->em = null; // avoid memory leaks
    }
}

谁知道为什么会这样？一个bug？

编辑:

显然.env文件读取不正确.我将DATABASE_URL环境变量移动到doctrine.yml文件中,现在它可以工作了.

你必须把它DATABASE_URL放到你的phpunit.xml文件中,例如:

<php>
        <ini name="error_reporting" value="-1" />
        <env name="KERNEL_CLASS" value="App\Kernel" />
        <env name="APP_ENV" value="test" />

        <!-- ###+ doctrine/doctrine-bundle ### -->
        <!-- Format described at http://docs.doctrine-project.org/projects/doctrine-dbal/en/latest/reference/configuration.html#connecting-using-a-url -->
        <!-- For an SQLite database, use: "sqlite:///%kernel.project_dir%/var/data.db" -->
        <!-- Configure your db driver and server_version in config/packages/doctrine.yaml -->
        <env name="DATABASE_URL" value="mysql://root@127.0.0.1:3306/symfony4-database"/>
        <!-- ###- doctrine/doctrine-bundle ### -->
    </php>
