Error test upload php unit symfony2 - forms

Question

Im following the tutorial from symfony's website to make my phpunit's test for my controller.
Im trying to test an upload on a form and i have 3 fields on this form : title,description and file.
I use :
public function testScenarioAdd() {
$client = static::createClient();
$x_wsse = 'UsernameToken Username="username#fai.fr", PasswordDigest="aeirugbjcUbfmùJK", Nonce="OTMzOGMwYzFkYTk2MzJmYzBh", Created="2013-11-12T10:22:15+01:00"';
//X_Wsse is for the connection systeme on my application.
$image = new UploadedFile(
'/past/to/your/images.jpg',
'images.jpg',
'image/jpeg',
100000
);
$crawler = $client->request('POST', '/ad/create', array('ad_form' => array('title' => 'test', 'description' => 'Test description')),array(), array('CONTENT_TYPE' => 'application/x-www-form-urlencoded', 'HTTP_X-WSSE' => $x_wsse));
$response = $client->getResponse()->getContent();
$json_response = json_decode($response);
print_r($response);
}
When i launch it I have an error saying :
{"app_error":{"success":500,"result":[{"message":"Array to string conversion",...
Am i doing something wrong ? or missing something in my code ?
Thanks for your help :)
Edit :
Thanks but, what ive done there is working on another test without upload, i still tried it and its not working. I still have the error array to string... I think it come from the fonction UplaodedFile or maybe from my controller itself because when i try the other solution from symfony's web site with
$photo = array(
'tmp_name' => '/path/to/photo.jpg',
'name' => 'photo.jpg',
'type' => 'image/jpeg',
'size' => 123,
'error' => UPLOAD_ERR_OK
);
With putting the
$crawler = $client->request('POST', '/ad/create', array('ad_form[title]' => 'test', ad_form[description] => 'test description'),array('file' => $image),array('CONTENT_TYPE' => 'application/x-www-form-urlencoded', 'HTTP_X-WSSE' => $x_wsse));
The important part of my controller is :
if ('POST' === $request->getMethod()) {
$form->bind($request);
if ($form->isValid())
{
$Ad->preCreate();
$odm->persist($Ad);
$odm->flush();
$odm->clear();
$data = $this->listAction($request, 1, 5);
Tags::setEvent($request, $this->container, 'member.create.ad', $user->getId(), $Ad->getId());
return $data;
} else {
$data = Errors::formatJson($form, $this->container);
}
}
}
return new JsonResponse(array('ad_create' => $data));
Im kinda new in symfony, i really dont know where this error can come from...

Client::Request method expects you to provide it with one-dimensional array of data. So try this code:
<?php
//...
$crawler = $client->request('POST', '/ad/create',
array('ad_form[title]' => 'test',
'ad_form[description]' => 'Test description'),
array(),
array('CONTENT_TYPE' => 'application/x-www-form-urlencoded', 'HTTP_X-WSSE' => $x_wsse));
