Laravel Testing Issue: Mocking Event Facade

Laravel provides helpers for mocking events, jobs, and facades out of the box. These helpers primarily provide a convenience layer over Mockery so you do not have to manually make complicated Mockery method calls.

Today first time I used Event::fake() and faced really weird issue when I run tests.

public function testPostCreating()
{
    Event::fake();
    $response = $this->json('POST', '/api/v1/posts', [
        'title' => 'Example Post',
    ]);
    Event::assertDispatched(PostCreated::class);
}

Event facade's fake method prevents all event listeners from executing. And because of we're generating UUID from our model events I got exception below:

[2019-08-09 14:30:22] testing.ERROR: SQLSTATE[23502]: Not null violation: 7 ERROR:  null value in column "id" violates not-null constraint

I found quick, dirty workaround to fix:

public function testPostCreating()
{
    $initialDispatcher = Event::getFacadeRoot();

    Event::fake();

    Model::setEventDispatcher($initialDispatcher);
    $response = $this->json('POST', '/api/v1/posts', [
        'title' => 'Example Post',
    ]);
    Event::assertDispatched(PostCreated::class);
}
