<?php

namespace Tests\Unit\Jobs;

use Tests\TestCase;
use Illuminate\Support\Facades\Queue;
use Illuminate\Foundation\Testing\DatabaseTransactions;

class FirstJobTest extends TestCase
{
    use DatabaseTransactions;

    /** @test */
    public function it_asks_every_employee_to_rate_the_given_manager(): void
    {
        // The FirstJob() dispatched another job, called SecondJob().
        // We need to omit this job from the Queue facade's fake method so we can assert that
        // the second job was pushed.
        
        Queue::fake()->except([FirstJob::class]);
        
        // Now we may dispatch the first job normally
        FirstJob::dispatch();

        // Having been allowed to operate normally, the first job will push second job to the fake queue.
        Queue::assertPushed(SecondJob::class);
    }
}
