Laravel Listener not fired even though the event was triggered

Question

I am developing a web application using Laravel framework. I am trying to trying to use event and listener in my application. But the event was trigged and the listener for the trigged event is not fired.

This is my controller action

    public function store(Request $request)
    {

        //other code
        $item = Item::create($request->all())
        broadcast(new ItemCreated($item));
        return "Item created successfully";
    }

This is my Events\ItemCreated.php

class ItemCreated
{
    use Dispatchable, InteractsWithSockets, SerializesModels;

    public $item;

    public function __construct($item)
    {
        $this->item = $item;
    }
}

Then I have a listener for that event.

Listeners/EmailSubscribedUsers.php

class EmailSubscribedUsers
{

    public function __construct()
    {
        //this constructor is not triggered
    }


    public function handle(ItemCreated $event)
    {
        //This method is not fired
    } 
}

In the EventServiceProvider I registered the event and the listener like this

protected $listen = [

    ItemCreated::class => [
        EmailSubscribedUsers::class
    ]
];

The event is trigged. But the listener is not fired. Why? What is wrong?

I tried the following solutions.

php artisan optimize
composer dumpautoload
php artisan clear-compiled

What version are you running? optimize and clear-compiled haven't been used in a while. — Devon Bessemer, Oct 17 '18 at 16:57
I'm guessing your actual code differs from what you've posted. For example, is your listener `queueable`? If yes, did you run `artisan queue:work`? — Paras, Oct 17 '18 at 16:59
My sense is that if you post your `real` code, we may be able to help — Paras, Oct 17 '18 at 17:00
That is the real code. So empty coz I am trying the event and the listener — Wai Yan Hein, Oct 17 '18 at 17:02

Sorry everyone. The issue was I was unit testing. In the unit testing if I used Event::fake(), the event listeners are not triggered. I wanted to tested the logic in the event listeners. Therefore, I removed the Event::fake() and tested the logic in the listener instead.

First of all as pointed in comments use

event(new ItemCreated($item));

and not

broadcast(new ItemCreated($item));

In addition make sure you have set QUEUE_CONNECTION to sync in your .env file. If you used some other connection (for example database or Redis) make sure you run in console command:

php artisan queue:work

The last thing - verify your error log in storage/logs directory. You might have some other errors (for example missing import) and that's why your listener fails.

Also make sure in EventServiceProvider that you use valid classes and imported valid namespaces - otherwise listener won't be triggered.

Actually the listener is fired. It is just not fired in the unit test. – Wai Yan Hein Oct 17 '18 at 17:51
@WaiYanHein Well, you haven't mentioned that in your question. How do you know it's not fired? Do you know that in `phpunit.xml` there might be different driver set for queues? How your test look like? – Marcin Nabiałek Oct 17 '18 at 17:54
I will post my test later – Wai Yan Hein Oct 17 '18 at 17:59
QUEUE_CONNECTION to sync solve my problem – Kim Tormes Jun 02 '21 at 04:46
