Manually calling "createWithAttributes" does not work because Event is not called

[renepardon]

This is my method within Upload model:

    public static function createWithAttributes(array $attributes): self
    {
        $attributes['id'] = Str::orderedUuid()->toString();

        event(new UploadCreated($attributes));

        return static::uuid($attributes['id']);
    }

I try to call it like that within my test and it fails because return value of createWithAttributes is null:

    public function test_model_triggers_event_on_creation()
    {
        Event::fake();

        Upload::createWithAttributes($this->getFakeUploadAttributes($this->user, true));

        Event::assertDispatched(UploadCreated::class);
    }

BUT this works:

    $aggregate = UploadAggregate::retrieve(self::UPLOAD_UUID)
            ->createUpload($this->getFakeUploadAttributes($user))
            ->persist();

    return Upload::uuid($aggregate->uuid());

Is there something I miss? Shouldn't the events be called synchronous and Projector be called immediately which persists the model instance?

    public function onUploadCreated(UploadCreated $event)
    {
        Upload::create($event->attributes);
    }

static::uuid is just a helper as shown in the documentation. (https://spatie.be/docs/laravel-event-sourcing/v6/using-projectors/writing-your-first-projector)

I think your events aren't dispatched because you're calling Event::fake(); our event bus hooks into Laravel's event bus, so faking it will simply not trigger anything on the event-sourcing side.

Maybe the testing aggregates section in the docs can help you point in the right direction.

Yes I figured it out, that Event::fake() is the problem here. But without calling Event::fake() the corresponding assertion Event::assertDispatched() is not available as well which makes it a chicken-egg-problem.

Testing the aggregates will not test the Model method itself, sadly. The provided link returns a HTTP 504 right now

Have you considered using Projectionist::fake() ? https://github.com/spatie/laravel-event-sourcing/blob/main/src/Projectionist.php#L39
