Testing File uploads in Symfony2

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. https://github.com/symfony/symfony/pull/1891

I think that this question should be closed or mark as answered, I've follow this conversation: github.com/symfony/symfony/pull/1891 and it seems that was just a problem with documentation. — Claudio Acciaresi

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));

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()
    );
}

on the created UploadedFile object $file->isValid() fails. any idea why?

@astroanu please add a new question to explain your problem.

Still works on Symfony 5.0, except the UploadedFile constructor removes the file size and added error & test.

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);

The fifth parameter active the "test" mode, in order to not trigger HTTP real upload in test.

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

this is a much better solution. Unit test where you can!

Please include the code in your answer so your answer will be still valid if the page disappear.

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');
