PB Functional test symfony2 controller - symfony

Question

I try to do a functional test on a controller that executes doctrine. When I execute my test, it fails. but when I commented in my controller this line:"$products = $em->getRepository("Couture\FrontBundle\Entity\Produit")->findAll()".
my test is success.
this is my controller:
class ProductController extends Controller {
/**
* Get products
* #Route("/products")
* #Method("GET")
*/
public function getAllAction() {
$serialize = $this->get('jms_serializer');
$em = $this->getDoctrine();
$products = $em->getRepository('Couture\FrontBundle\Entity\Produit')->findAll();
if (!$products) {
$response = new Response(json_encode(array('error' => 'Resources not found for products')));
$response->headers->set('Content-Type', 'application/json');
$response->setStatusCode('400');
return $response;
}
$response = new Response($serialize->serialize($products, 'json'));
$response->headers->set('Content-Type', 'application/json');
return $response;
}
}
this is my class test:
class ProductControllerTest extends WebTestCase {
public function testGetAll() {
$client = static::createClient();
$client->request('GET', $client->getContainer()->get('router')->generate('couture_front_product_getall'));
$this->assertEquals(
200, $client->getResponse()->getStatusCode()
);
}
}

Answer 1

When you comment that line, !$products is false and then your controller return a Reponse object with application/json content-type header. This response is considered as successful because its status code is 200 OK.
What I have seen in such scenario, is the use of data fixtures to test entities managed by doctrine entityManager.
Your test class may look like this ( not tested code, just to give you the idea behind):
class ProductControllerTest extends WebTestCase {
public function testGetAll() {
$client = static::createClient();
$fixtures = array('Acme\YourBundle\dataFixtures\LoadProductData');
$this->loadFixtures($fixtures);
$uri= $this->getUrl('couture_front_product_getall');
$crawler= $client->request('GET',$uri);
$this->assertEquals(200,$client->getResponse()->getStatusCode() );
}
}
