本文档本章说明如何从不同位置运行命令。请注意，用于满足您的需求是相当肮脏的解决方案...exec()

在Symfony2中执行控制台命令的正确方法如下：

备选案文一

use Symfony\Bundle\FrameworkBundle\Console\Application as App;
use Symfony\Component\Console\Tester\CommandTester;

class YourTest extends WebTestCase
{
    public function setUp()
    {
        $kernel = $this->createKernel();
        $kernel->boot();

        $application = new App($kernel);
        $application->add(new YourCommand());

        $command = $application->find('your:command:name');
        $commandTester = new CommandTester($command);
        $commandTester->execute(array('command' => $command->getName()));
    }
}

备选案文二

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

class YourClass extends WebTestCase
{
    protected static $application;

    public function setUp()
    {
        self::runCommand('your:command:name');
        // you can also specify an environment:
        // self::runCommand('your:command:name --env=test');
    }

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

        return self::getApplication()->run(new StringInput($command));
    }

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

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

        return self::$application;
    }
}

P.S. 伙计们，不要因为打电话给exec（）而羞辱Symfony2...

文档会告诉您建议的方法来执行此操作。示例代码粘贴在下面：

protected function execute(InputInterface $input, OutputInterface $output)
{
    $command = $this->getApplication()->find('demo:greet');

    $arguments = array(
        'command' => 'demo:greet',
        'name'    => 'Fabien',
        '--yell'  => true,
    );

    $input = new ArrayInput($arguments);
    $returnCode = $command->run($input, $output);

    // ...
}
