[Laravel] ファイルアップロードのテストの書き方

公式サイトのサンプルコードが参考になる。

<?php

namespace Tests\Feature;

use Tests\TestCase;
use Illuminate\Http\UploadedFile;
use Illuminate\Support\Facades\Storage;
use Illuminate\Foundation\Testing\RefreshDatabase;
use Illuminate\Foundation\Testing\WithoutMiddleware;

class ExampleTest extends TestCase{

    public function testAvatarUpload()
    {
        Storage::fake('avatars');

        $file = UploadedFile::fake()->image('avatar.jpg');

        $response = $this->json('POST', '/avatar', [
            'avatar' => $file,
        ]);

        // Assert the file was stored...
        Storage::disk('avatars')->assertExists($file->hashName());

        // Assert a file does not exist...
        Storage::disk('avatars')->assertMissing('missing.jpg');
    }
}
