Public function test_is_attached_to_event() Tip 3 - Assert your event listener is attached to the event you expect eloquent events

All of these things are already tested in our controller test. We don’t care how the user gets created (that’s why we’re using the factory) or how the event is dispatched (in this case it’s not being dispatched at all). We ‘re making sure this job does what it needs to do and we only care about testing if the notifications are sent. The most important part of this test is that we’re manually creating ( $listener = new SendUserCreatedNotifications()) and running $listener->handle($event) our listener. Mail::assertSent(NewUserCreatedAdminNotification::class) Notification::assertSentTo($user, WelcomeNotification::class) $listener = new SendUserCreatedNotifications() I’m calling this a unit test here because we’ll be manually instantiating the class and performing its actions, even if it touches filesystem, databases, etc. In order to keep this article from getting too long, we’re going to choose one of our listeners and use it as an example, but the concepts apply to any event listener.

Asserting that our listeners are attached to the expected events.

Testing the functionality inside our event listener classes.

…So, are we done? To have good test coverage in this feature, we’re still missing a couple of things: This makes our test more reliable, as it cannot break when any of those things change. It doesn’t assert that email notifications were sent, or if the commission was created. Our controller test is only making sure the UserCreated event was dispatched. $this->assertDatabaseHas('users', ) Įvent::assertDispatched(UserCreated::class) The mocking tools are really great, and in this case we are going to make use of Event::fake(). Laravel gives us some really great tools for testing. Tip 1 - Event::fake() for integration tests We don’t want our controller test to break when other things change, which leads us to our testing tip number 1. So, we’re going to start with our controller. Why is my user-creation test breaking after I modified the fancy marketing system we integrate with? We could spend hours talking about resilient tests, but for now let’s just say that no one likes having to fix a bunch of seemingly unrelated tests because you changed something. [īesides having good test coverage in our system where we want to be confident when refactoring our code, we want to have tests which are easy to understand and *resilient*. The Open/Closed Principle (OCP) states that “Software entities (classes, modules, functions, etc.) should be open for extension, but closed for modification.”.

As a bonus here, we’re respecting one of the SOLID principles of software development. This seems like a perfect case to make use of event listeners, so that’s what we’re going to do. Also, our controller wouldn’t look that good. Placing them directly in the controller feels a bit weird since they are more like side effects from our main action (user registration). There are a few actions we need to perform when a new user signs up. This is how our controller looks, simple and clean: all())

Since everything is better with an example, picture a system that needs to perform a couple of things when a new user signs up. In this article, we explore one simple yet powerful and scalable approach to setting up and testing your events and listeners. They can run synchronously or asynchronously (by running in the queue). Note: Use and implement method 1 because this method fully tested our system.Īll methods was sourced from or, is licensed under cc by-sa 2.5, cc by-sa 3.0 and cc by-sa 4.It allows you to dispatch events and attach a set of event listeners to that specific event which are run automatically. This is because the models are never actually retrieved when issuing a mass update.

#ELOQUENT EVENTS UPDATE#

When issuing a mass update via Eloquent, the saved and updated model events will not be fired for the updated models. The row is not updated at all – no changes. This will fire the update event: User::find($id)->update()

Where is it from? from other service provider?Īny explanation or hint will be appreciated! update()

#ELOQUENT EVENTS CODE#

Just had a beginner’s question, when I am trying to use service provider and model event to log the update information.Īfter put all code together, I find that the model event only fire when create the use but never log anything when I edit the user.ĭid I miss anything? Feel like the $user didn’t get assigned properly. All we need is an easy explanation of the problem, so here it is.
