php - 如何测试使用尝试功能的 laravel 作业的第二次尝试逻辑

Question

我有一个排队的作业类，由于该backoff()方法，它呈指数级后退。我想测试该backoff()方法是否正确。它应该2, 4, 8, 16在每次重试后创建等等。由于attempts()函数属于特征并从更深的类的有效负载InteractsWithQueue中读取尝试计数，我找不到合适的方法来测试它。RedisJobdecoded

有什么帮助吗？

class AJob implements ShouldQueue
{
    use Dispatchable;
    use InteractsWithQueue;
    use Queueable;
    use SerializesModels;

    public $tries = 10; 

    public function backoff()
    {
        return pow(2, $this->attempts());
    }

    public function handle()
    {
        try{
            //Some logic
        }
        catch(Exception $e){
            $this->release($this->backoff());
        }
    }   
}

我解决了这个问题。这是解决方案。

public function test_backoff_after_fifth_attempt()
    {
        /** @var RedisJob $mockRedisJob */
        $mockRedisJob = $this->mock(
            RedisJob::class,
            function (MockInterface $mock) {
                $mock->shouldReceive('attempts')->once()
                     ->andReturn(5);
            }
        );

        $job = new SendMailJob(new Mail());
        $job->setJob($mockRedisJob);

        $this->assertEquals(32, $job->backoff());
    }
