Unit testing explicitly dispatching WebhookReceived event is not working - laravel

Question

I am building a Laravel application. I am using Laravel Cashier to handle subscription in my application. I am writing unit test for the Stripe Webhook creating a custom event listener for that.
I have an event listener like this:
class StripeEventListener
{
/**
* Create the event listener.
*
* #return void
*/
public function __construct()
{
//
}
/**
* Handle the event.
*
* #param object $event
* #return void
*/
public function handle(WebhookReceived $event)
{
if ($event->payload['type'] === 'invoice.payment_succeeded') {
// Handle the incoming event...
}
// TODO: write unit test for this event.
if ($event->payload['type'] === 'customer.subscription.updated') {
// Handle the incoming event...
// handleCustomerSubscriptionUpdated
if ($user = $this->getUserByStripeId($event->payload['data']['object']['customer'])) {
$data = $event->payload['data']['object'];
if (
isset($data['status']) &&
($data['status'] === StripeSubscription::STATUS_INCOMPLETE_EXPIRED ||
$data['status'] == StripeSubscription::STATUS_INCOMPLETE)
) {
if (! $user->payment_method_needs_updating) {
$user->payment_method_needs_updating = true;
$user->save();
}
}
}
}
}
protected function getUserByStripeId($stripeId)
{
return Cashier::findBillable($stripeId);
}
}
Then I bind that to WebhookReceived event in the EventServiceProvider like this:
protected $listen = [
WebhookReceived::class => [
StripeEventListener::class
],
Registered::class => [
SendEmailVerificationNotification::class,
],
];
I am unit testing the listener dispatching the WebhookReceived event like this:
WebhookReceived::dispatch([
.... mock data
]);
But I am getting this error:
Illuminate\Contracts\Container\BindingResolutionException
Target class [events] does not exist.

878▕ } catch (ReflectionException $e) {
➜ 879▕ throw new BindingResolutionException("Target class [$concrete] does not exist.", 0, $e);
880▕ }
How can I fix it or how can I unit test it?
