Test Failing on Project-Flyer

Not sure what's happening, but I am running Laravel 5.2. So, that could be a problem, but I am very uncertain as I have never written a test before so I wouldn't understand how to read the error. I mean, it obviously has something to do with the move method or something. Anyhoo...

AddPhotoToFlyerTest.php

<?php

// namespace App;

use App\AddPhotoToFlyer;
use Symfony\Component\HttpFoundation\File\UploadedFile;
use Mockery as m;

use Illuminate\Foundation\Testing\WithoutMiddleware;
use Illuminate\Foundation\Testing\DatabaseMigrations;
use Illuminate\Foundation\Testing\DatabaseTransactions;

class AddPhotoToFlyerTest extends TestCase
{
    /**
     * A basic test example.
     *
     * @return void
     */
    public function test_it_processes_a_form_to_add_a_photo_to_a_flyer()
    {
        $flyer = factory(App\Flyer::class)->create();

        $file = m::mock(UploadedFile::class, [
            'getClientOriginalName' => 'foo',
            'getClientOriginalExtension' => 'jpg'
        ]);

        $file->shouldReceive('move')
            ->once()
            ->with('flyer_imgs/photos', 'nowfoo.jpg');

        $thumbnail = m::mock(App\Thumbnail::class);

        $thumbnail->shouldReceive('make')
            ->once()
            ->with('flyer_imgs/photos/nowfoo.jpg', 'flyer_imgs/photos/tn-nowfoo.jpg');

        (new AddPhotoToFlyer($flyer, $file, $thumbnail))->save();

        $this->assertCount(1, $flyer->photos);
    }
}

My test results after running:
