Symfony 3.4-“在"doctrine:schema"命名空间中未定义命令"尝试在类中运行控制台命令时 [英] Symfony 3.4 - "no commands defined in the “doctrine:schema” namespace" when attempting to run console command in class

问题描述

我正在与此博客一起创建广告单元以我的数据装置为基础的测试.相关代码:

I'm following along with this blog to create unit tests that use my data fixtures as a base. The relevant code:

namespace Tests\AppBundle\Repository;

use Symfony\Component\Console\Application;
use Symfony\Component\Console\Input\StringInput;
use Symfony\Bundle\FrameworkBundle\Test\WebTestCase;

class DataFixtureTestCase extends WebTestCase
{
    protected $client, $container, $em;
    protected static $application;

    /**
     * {@inheritdoc}
     */
    protected function setUp()
    {
        self::runCommand('doctrine:schema:drop --force');
        self::runCommand('doctrine:schema:create');
        self::runCommand('doctrine:fixtures:load --append --no-interaction --force');

        $this->client = static::createClient();
        $this->container = $this->client->getContainer();
        $this->em = $this->container->get('doctrine')->getManager();
    }

    protected static function runCommand($command)
    {
        $command = sprintf('%s --quiet', $command);

        try {
            return self::getApplication()->run(new StringInput($command));
        } catch(\Exception $e) {
            echo $e->getMessage();
        }
    }

    protected static function getApplication()
    {
        if (null === self::$application) {
            $client = static::createClient();

            self::$application = new Application($client->getKernel());
            self::$application->setAutoExit(false);
        }

        return self::$application;
    }

    // other methods not relevant to the question

我的单元测试类扩展了DataFixtureTestCase.调用setUp()时，我不断收到如下错误:

My unit test classes extend DataFixtureTestCase. When setUp() is invoked, I keep getting errors like:

在"doctrine:schema"命名空间中没有定义命令

There are no commands defined in the "doctrine:schema" namespace

关于什么原因的任何想法?我的研究尚未发现错误的原因.通过Composer正确安装了Doctrine，我可以在终端中手动运行控制台命令.

Any ideas on what's causing this? My research hasn't revealed the cause of the error. Doctrine is correctly installed via Composer, and I can run the console commands manually in a terminal.

推荐答案

您的问题是为此使用了错误的 Application 类.

Your problem is that you are using the wrong Application class for this.

查看您的 bin/console php文件. github链接

Have a look at your bin/console php file. github link

更改:

use Symfony\Component\Console\Application;

到

use Symfony\Bundle\FrameworkBundle\Console\Application;
