[11.x] Fake Queue Interactions

[taylorotwell]

Currently, it's not obvious how to assert that a job was released, deleted, or manually failed from within the job itself. For example, given this job handle method:

public function handle(): void
{
    if ($someCondition) {
        $this->release(30);
    }
}

It is not clear to the end user how to test this nor is it documented. The best way to do this currently would be to extend your job class and define stub / fake methods for release, delete, and fail.

This PR introduces a new withFakeQueueInteractions method on the InteractsWithQueue trait as well as relevant assertions. Now the job above could be tested like so:

public function test_job_is_released(): void
{
    $job = (new TestJob)->withFakeQueueInteractions();

    $job->handle();

    $job->assertReleased(30);

    // $job->assertDeleted();
    // $job->assertFailed();
}
