Testando Comandos do Container Aware no Symfony2

Se o seu comando for estendido SymfonyBundleFrameworkBundleCommandContainerAwareCommand, você também precisará usar SymfonyBundleFrameworkBundleConsoleApplicationpara testar o comando em vez da base SymfonyComponentConsoleApplication.

Sua classe de teste também deve estender SymfonyBundleFrameworkBundleTestWebTestCasee inicializar um kernel para obter um contexto utilizável em seu comando.

Exemplo:

use SymfonyBundleFrameworkBundleTestWebTestCase;
use SymfonyBundleFrameworkBundleConsoleApplication;
use SymfonyComponentConsoleTesterCommandTester;
use VLIZToolboxBundleCommandDownloadCommand;

class DownloadCommandTest extends WebTestCase
{
    /**
     * @inheritDoc
     */
    protected function setUp()
    {
        static::$kernel = static::createKernel();
        static::$kernel->boot();
    }

    public function testDownload()
    {
        $application = new Application(static::$kernel);
        $application->add(new DownloadCommand());

        $command = $application->find('demo:greet');
        $command->setApplication($application);
        $commandTester = new CommandTester($command);
        $commandTester->execute(
                array(
                    'command'      => $command->getName(),
                    'name'         => 'Fabien',
                    '--iterations' => 5,
        );

        $this->assertRegExp('/Fabien/', $commandTester->getDisplay());
    }
}
