PHPUnit 7无法识别我的Symfony 3.4 @required for setters

Question

I am attempting to test the following Symfony 3.4 CLI command class with PHPUnit 7.

class SubscribeUsers extends ContainerAwareCommand
{
    use LoggerTrait;

    use DalcioTrait;

I have a bunch of traits, with this typical format:

DalcioTrait.php

trait DalcioTrait
{
    /**
     * @var Dalcio
     */
    protected $dalcio;

    /**
     * @required
     * @param Dalcio $dalcio
     */
    public function setDalcio(Dalcio $dalcio)
    {
        $this->dalcio = $dalcio;
    }

    /**
     * @return Dalcio
     */
    public function getDalcio(): Dalcio
    {
        return $this->dalcio;
    }
}

In my test I have the following:

    $commandTester = new CommandTester($command);
    $commandTester->execute(['command' => $command->getName()]);

and that is where it falls over because where I call $this->getLogger() or $this->getDalcio() in SubscribeUsers it falls over because they are both NULL.

I am using the Symfony 3.4 @required annotation because I am now using autowired services and no longer explicitly calling setters in my service definitions.

Is there any way to have PHPUnit 7 recognise these annotations?
