Public function test_is_attached_to_event() Tip 3 - Assert your event listener is attached to the event you expect handle($event) our listener. Mail::assertSent(NewUserCreatedAdminNotification::class) Notification::assertSentTo($user, WelcomeNotification::class) $listener = new SendUserCreatedNotifications() IвЂ™m calling this a unit test here because weвЂ™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, weвЂ™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.

вЂ¦So, are we done? To have good test coverage in this feature, weвЂ™re still missing a couple of things: This makes our test more reliable, as it cannot break when any of those things change. It doesnвЂ™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', ) Д®vent::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 donвЂ™t want our controller test to break when other things change, which leads us to our testing tip number 1. So, weвЂ™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 letвЂ™s just say that no one likes having to fix a bunch of seemingly unrelated tests because you changed something. [Д«esides 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 вЂњSoftware entities (classes, modules, functions, etc.) should be open for extension, but closed for modification.вЂќ.

As a bonus here, weвЂ™re respecting one of the SOLID principles of software development. This seems like a perfect case to make use of event listeners, so thatвЂ™s what weвЂ™re going to do. Also, our controller wouldnвЂ™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). Php artisan make:model Flight php artisan make:model Flight -migration # Generate a model and a FlightFactory class.php artisan make:model Flight -factoryphp artisan make:model Flight -fВ # Generate a model and a FlightSeeder class.php artisan make:model Flight -seedphp artisan make:model Flight -sВ # Generate a model and a FlightController class.php artisan make:model Flight -controllerphp artisan make:model Flight -cВ # Generate a model, FlightController resource class, and form request classes.php artisan make:model Flight -controller -resource -requestsphp artisan make:model Flight -crRВ # Generate a model and a FlightPolicy class.php artisan make:model Flight -policyВ # Generate a model and a migration, factory, seeder, and controller.php artisan make:model Flight -mfscВ # Shortcut to generate a model, migration, factory, seeder, policy, controller, and form requests.php artisan make:model Flight -allВ # Generate a pivot model.It allows you to dispatch events and attach a set of event listeners to that specific event which are run automatically.
