Symfony PHPUnit Test ( error 500 ) - php

Question

Im testing this function
/**
* #Route("/list", name="_clients")
* #Method("GET")
*/
public function ClientsAction()
{
$em = $this->getDoctrine()->getManager();
$data = $em->getRepository('InvoiceBundle:Clients')->findByUser($this->user());
if($data){
$Clients = array();
foreach($data as $v){
if($v->getCompanyId() != 0 ) {
$companyId = $v->getCompanyId();
} else {
$companyId = '';
}
if ($v->getClient() == 'person'){
$company = $v->getName().' '.$v->getLname();
} else {
$company = $v->getCompany();
}
$Clients[] = array(
'id' => $v->getId(),
'settings' => $company,
'companyId' => $companyId,
'client' => $v->getClient(),
'mobile' => $v->getMobile(),
'email' => $v->getEmail(),
'clientName' => $v->getClientName(),
'delivery' => $v->getDelivery(),
'ContactPerson' => $v->getContactPerson()
);
}
} else {
$Clients = array('data' => 'empty');
}
$response = new JsonResponse($Clients);
return $response;
}
The function it self runs correctly , but then i want to check if my 'Content-Type' is Json with this function
public function testClients()
{
$client = static::createClient();
$client->request('GET', '/clients/list');
$this->assertTrue(
$client->getResponse()->headers->contains(
'Content-Type',
'application/json'
)
);
}
with this i get a FALSE value.
Then i try to do a test for Status code
$this->assertSame(200, $client->getResponse()->getStatusCode());
With this i get error 500 instead of 200 OK
I understand that is why i get a FALSE value in my 'Content-Type' test but i cant get why.
Im doing all this according to the Symfony documentation.
May be i'm doing something wrong or is it just that you cant check the 'Content-Type'?
Any help would be appreciated!

Answer 1

JsonResponse does add the Content-Type header (application/json) so this should not be an issue.
I think the main issue is that you are missing $ on the client->request() line.
Edit :
Before the declaration of your class, did you add #Route("/clients") ?
Or, maybe the data returned by findByUser is not what you expected and calls to $v fail.
