How to prevent Laravel event() from firing during unit tests

I have a class that uses Laravel’s global event() function to fire off a single event when a model is changed. The only way I have been able to prevent this event from firing during unit tests is to actually namespace and declare a new event() function in the test itself and make it do nothing. It works, but it doesn’t seem like a pretty solution to me. I looked into the Laravel docs and I can see some people have used Event::fake() inside the test successfully, but when I try to do it I get:

BadMethodCallException: Method Mockery_0_Illuminate_Contracts_Events_Dispatcher::until() does not exist on this mock object

I’m on Laravel 5.4. Is there a cleaner way to prevent this event from firing during a test? I really dislike the idea of declaring an empty namespaced event() function.

EDIT:

The class I am testing is a UserDomain class. In one part of the logic it invokes Laravel’s global event() method:

event(new RoleChanged($this->user));

To suppress this from firing in a test I have tried Event::fake() and I have also tried using the trait WithoutEvents and its withoutEvents() method. Neither work, and the same error I mentioned above occurs both times.

Answer

I read some more docs on mocking in Laravel unit testing and I discovered that all I had to do is this at the beginning of the test:

$this->expectsEvents(RoleChanged::class);

This tells framework to acknowledge this event occurred but to not actually fire it off. Thanks everybody for your help. It led me to a workable solution.
