How do I test subdomain based routes in Symfony2 - symfony

Question

I have a app which uses subdomains to route to agencies:
foo.domain.dev -> Agency:showAction(foo)
bar.domain.dev -> Agency:showAction(bar)
domain.dev -> Agency:indexAction()
These each correspond to an Agency entity and controller.
I have a listener that listens for the onDomainParse event and writes the subdomain into the request attributes.
/**
* Listens for on domainParse event
* Writes to request attributes
*/
class SubdomainListener {
public function onDomainParse(Event $event)
{
$request = $event->getRequest();
$session = $request->getSession();
// Split the host name into tokens
$tokens = $this->tokenizeHost($request->getHost());
if (isset($tokens['subdomain'])){
$request->attributes->set('_subdomain',$tokens['subdomain']);
}
}
//...
}
I then use this in the controller to reroute to a show action:
class AgencyController extends Controller
{
/**
* Lists all Agency entities.
*
*/
public function indexAction()
{
// We reroute to show action here.
$subdomain = $this->getRequest()
->attributes
->get('_subdomain');
if ($subdomain)
return $this->showAction($subdomain);
$em = $this->getDoctrine()->getEntityManager();
$agencies = $em->getRepository('NordRvisnCoreBundle:Agency')->findAll();
return $this->render('NordRvisnCoreBundle:Agency:index.html.twig', array(
'agencies' => $agencies
));
}
// ...
}
My question is:
How do i fake this when doing a test with WebTestCase?

Answer 1

Visit the subdomain by overriding HTTP headers for the request and test for the right page:
Untested, may contain errors
class AgencyControllerTest extends WebTestCase
{
public function testShowFoo()
{
$client = static::createClient();
$crawler = $client->request('GET', '/', array(), array(), array(
'HTTP_HOST' => 'foo.domain.dev',
'HTTP_USER_AGENT' => 'Symfony/2.0',
));
$this->assertGreaterThan(0, $crawler->filter('html:contains("Text of foo domain")')->count());
}
}

Based on the Symfony docs on host-based routes, Testing your Controllers:
$crawler = $client->request(
'GET',
'/',
array(),
array(),
array('HTTP_HOST' => 'foo.domain.dev')
);
If you don't want to pad all your requests with array parameters, this might be better:
$client->setServerParameter('HTTP_HOST', 'foo.domain.dev');
$crawler = $client->request('GET', '/');
...
$crawler2 = $client->request('GET', /foo'); // still sends the HTTP_HOST
There's also a setServerParameters() method on the client, if you have a few parameters to change.
