Testing Container Aware Commands in Symfony2

If your command is extending Symfony\Bundle\FrameworkBundle\Command\ContainerAwareCommand, you also need to use Symfony\Bundle\FrameworkBundle\Console\Application to test the command instead of the base Symfony\Component\Console\Application.

Your test class should also extend Symfony\Bundle\FrameworkBundle\Test\WebTestCase and initialize a kernel in order to get usable context within your command.

Example:

use Symfony\Bundle\FrameworkBundle\Test\WebTestCase;
use Symfony\Bundle\FrameworkBundle\Console\Application;
use Symfony\Component\Console\Tester\CommandTester;
use VLIZ\ToolboxBundle\Command\DownloadCommand;

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());
 }
}
