Event::fake() does not replace dispatcher for guard

[OwlManAtt]

• Laravel Version: 5.7.25
• PHP Version: 7.2.9

Description:

Per the docs, no listeners should be executed after running Event::fake().

The auth guard is not informed that Illuminate\Support\Testing\Fakes\EventFake should be used for dispatching events.

When I call Auth::login($user), it is dispatching Illuminate\Auth\Events\Login to the real event dispatcher & my listener is being executed.

Steps To Reproduce:

Succinctly:

>>> Event::fake()
=> null
>>> Auth::guard()->getDispatcher()
=> Illuminate\Events\Dispatcher {#25}

Workaround:

In a test that I don't want to have my listeners executed:

<?php

namespace Tests;

use Tests\TestCase;
use Illuminate\Support\Facades\Auth;
use Illuminate\Support\Facades\Event;

class FooTest extends TestCase
{
    public function test_login_flow()
    {
        Event::fake();
        Auth::guard()->setDispatcher(app('events'));

        // . . .
    }
}
