Testing File uploads in Symfony2 - symfony

Question

In the Symfony2 documentation it gives the simple example of:
$client->request('POST', '/submit', array('name' => 'Fabien'), array('photo' => '/path/to/photo'));
To simulate a file upload.
However in all my tests I am getting nothing in the $request object in the app and nothing in the $_FILES array.
Here is a simple WebTestCase which is failing. It is self contained and tests the request that the $client constructs based on the parameters you pass in. It's not testing the app.
class UploadTest extends WebTestCase {
public function testNewPhotos() {
$client = $this->createClient();
$client->request(
'POST',
'/submit',
array('name' => 'Fabien'),
array('photo' => __FILE__)
);
$this->assertEquals(1, count($client->getRequest()->files->all()));
}
}
Just to be clear. This is not a question about how to do file uploads, that I can do. It is about how to test them in Symfony2.
Edit
I'm convinced I'm doing it right. So I've created a test for the Framework and made a pull request.

Answer 1

This was an error in the documentation.
Fixed here:
use Symfony\Component\HttpFoundation\File\UploadedFile;
$photo = new UploadedFile('/path/to/photo.jpg', 'photo.jpg', 'image/jpeg', 123);
// or
$photo = array('tmp_name' => '/path/to/photo.jpg', 'name' => 'photo.jpg', 'type' => 'image/jpeg', 'size' => 123, 'error' => UPLOAD_ERR_OK);
$client = static::createClient();
$client->request('POST', '/submit', array('name' => 'Fabien'), array('photo' => $photo));

Answer 2

Here is a code which works with Symfony 2.3 (I didn't tried with another version):
I created an photo.jpg image file and put it in Acme\Bundle\Tests\uploads.
Here is an excerpt from Acme\Bundle\Tests\Controller\AcmeTest.php:
function testUpload()
{
// Open the page
...
// Select the file from the filesystem
$image = new UploadedFile(
// Path to the file to send
dirname(__FILE__).'/../uploads/photo.jpg',
// Name of the sent file
'filename.jpg',
// MIME type
'image/jpeg',
// Size of the file
9988
);
// Select the form (adapt it for your needs)
$form = $crawler->filter('input[type=submit]...')->form();
// Put the file in the upload field
$form['... name of your field ....']->upload($image);
// Send it
$crawler = $this->client->submit($form);
// Check that the file has been successfully sent
// (in my case the filename is displayed in a <a> link so I check
// that it appears on the page)
$this->assertEquals(
1,
$crawler->filter('a:contains("filename.jpg")')->count()
);
}

Answer 3

Even if the question is related to Symfony2, it appears in the top results when searching for Symfony4 in Google.
Instancing an UploadedFile works, but the shortest way I found was also actually in the official documentation:
$crawler = $client->request('GET', '/post/hello-world');
$buttonCrawlerNode = $crawler->selectButton('submit');
$form = $buttonCrawlerNode->form();
$form['photo']->upload('/path/to/lucas.jpg');

I found this article, https://coderwall.com/p/vp52ew/symfony2-unit-testing-uploaded-file, and works perfect.

if you want to mock a UploadedFile without a client request, you can use:
$path = 'path/to/file.test';
$originalName = 'original_name.test';
$file = new UploadedFile($path, $originalName, null, UPLOAD_ERR_OK, true);
$testSubject->method($file);
