Question

I\'m trying to run this functional test on my laravel controller. I would like to test image processing, but to do so I want to fake image uploading. How do I do this? I fou

Answer 1

With phpunit you can attach a file to a form by using attach() method.

Example from lumen docs:

public function testPhotoCanBeUploaded()
{
    $this->visit('/upload')
         ->name('File Name', 'name')
         ->attach($absolutePathToFile, 'photo')
         ->press('Upload')
         ->see('Upload Successful!');
}

Docs for CrawlerTrait.html#method_action reads:

Parameters
string $method
string $action
array $wildcards
array $parameters
array $cookies
array $files
array $server
string $content

So I assume the correct call should be

$response = $this->action(
    'POST',
    'FileStorageController@store',
    [],
    $values,
    [],
    ['file' => $uploadedFile]
);

unless it requires non-empty wildcards and cookies.

The best and Easiest way : First Import the Necessary things

use Illuminate\Http\UploadedFile;
use Illuminate\Support\Facades\Storage;

Then make a fake file to upload.

Storage::fake('local');
$file = UploadedFile::fake()->create('file.pdf');

Then make a JSON Data to pass the file. Example

$parameters =[
            'institute'=>'Allen Peter Institute',
            'total_marks'=>'100',
            'aggregate_marks'=>'78',
            'percentage'=>'78',
            'year'=>'2002',
            'qualification_document'=>$file,
        ];

Then send the Data to your API.

$user = User::where('email','candidate@fakemail.com')->first();

$response = $this->json('post', 'api/user', $parameters, $this->headers($user));

$response->assertStatus(200);

I hope it will work.

Add similar setUp() method into your testcase:

protected function setUp()
{
    parent::setUp();

    $_FILES = array(
        'image'    =>  array(
            'name'      =>  'test.jpg',
            'tmp_name'  =>  __DIR__ . '/_files/phpunit-test.jpg',
            'type'      =>  'image/jpeg',
            'size'      =>  499,
            'error'     =>  0
        )
    );
}

This will spoof your $_FILES global and let Laravel think that there is something uploaded.

For anyone else stumbling upon this question, you can nowadays do this:

    $response = $this->postJson('/product-import', [
        'file' => new \Illuminate\Http\UploadedFile(resource_path('test-files/large-avatar.jpg'), 'large-avatar.jpg', null, null, null, true),
    ]);

Here is a full example how to test with custom files. I needed this for parsing CSV files with known format so my files had to had exact formatting and contents. If you need just images or random sized files use $file->fake->image() or create() methods. Those come bundled with Laravel.

namespace Tests\Feature;

use Tests\TestCase;
use Illuminate\Http\UploadedFile;
use Illuminate\Support\Facades\Storage;

class PanelistImportTest extends TestCase
{
    /** @test */
    public function user_should_be_able_to_upload_csv_file()
    {
        // If your route requires authenticated user
        $user = Factory('App\User')->create();
        $this->actingAs($user);

        // Fake any disk here
        Storage::fake('local');

        $filePath='/tmp/randomstring.csv';

        // Create file
        file_put_contents($filePath, "HeaderA,HeaderB,HeaderC\n");

        $this->postJson('/upload', [
            'file' => new UploadedFile($filePath,'test.csv', null, null, null, true),
        ])->assertStatus(200);

        Storage::disk('local')->assertExists('test.csv');
    }
}

Here is the controller to go with it:

namespace App\Http\Controllers;

use Illuminate\Http\Request;
use App\Http\Controllers\Controller;
use Illuminate\Support\Facades\Storage;

class UploadController extends Controller
{
    public function save(Request $request)
    {
        $file = $request->file('file');

        Storage::disk('local')->putFileAs('', $file, $file->getClientOriginalName());

        return response([
            'message' => 'uploaded'
        ], 200);
    }
}
