Symfony4:Doctrine2 有效但在 PHPUnit 测试中没有连接(内核启动)

Symfony4: Doctrine2 works but no connection in PHPUnit test (kernel booted)

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

我遵循了文档中有关启动内核的步骤: 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
    }
}

有人知道为什么会这样吗?错误?

编辑:

显然 .env 文件没有被正确读取。我将 DATABASE_URL 环境变量移动到 doctrine.yml 文件中,现在可以使用了。

您必须将 DATABASE_URL 放入您的 phpunit.xml 文件中,例如像这样:

<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>
