How do I use retry?

<?php
namespace backend\job;

use yii\queue\RetryableJobInterface;

class TestPush implements RetryableJobInterface
{
    public $jobLogId;
    
    public function execute($queue)
    {
        var_dump($queue->attempts, $queue->ttr);
        echo '123123213213' , "\n";
        throw new \Exception(date("Y-m-d H:i:s"));
    }
    
    public function getTtr()
    {
        return 30;
    }
    
    public function canRetry($attempt, $error)
    {
        echo $attempt. " ============ canRetry \n";
        return true;
    }
}

output

1 ============ canRetry
The attempt is always 1

Start with the TestPush example in backend/job/TestPush.php and the RetryableJobInterface implementation, then reproduce the reported output with Yii 2.0.15.1 and PHP 7.2.5. Trace why the attempt value remains 1 after the exception; done means retries advance as expected and the behavior is covered by an appropriate test.
