symfony2 phpunit - functional testing error (host_with_path) - php

Question

So thanks to Matteo (phpunit in symfony2 - No tests executed) I can now test my functional tests.
Now I got the following error when running phpunit -c app:
You must change the main Request object in the front controller (app.php)
in order to use the `host_with_path` strategy.
so I did change it in the app.php, from:
$request = RequestFactory::createFromGlobals('host_with_path');
to:
$request = Request::createFromGlobals();
I also updated my swiftmailer-bundle from version 2.3 to 5.4.0.
Unfortunately This did not fix my error.
and this is my ../app/config_test.yml
swiftmailer:
disable_delivery: true
Am I missing something here?
I cannot seem to find this error anywhere on the web. Does someone know how I should fix this error?
After some searching I noticed that the app.php wasn't the problem. It was the DefaultControllerTest.php. The error could be fixed by removing the following lines from the DefaultControllerTest:
$crawler = $client->request('GET', '/hello/Fabien');
$this->assertTrue($crawler->filter('html:contains("Hello Fabien")')->count() > 0);
Due to recent developments our development team decided to stop using Sonata. As a side effect this bug got fixed. So I won't have a solution for this problem.

Answer 1

The problem here is, that the Client object is using neither app.php nor app_dev.php.
The client creates the request internally. So it won't be the request you need.
The only solution I can see is to override the method Symfony\Bundle\FrameworkBundle\Test\WebTestCase::createClient to return your own client. This client is than responsible for creating the actual request object. The following is the current behavior.
namespace Symfony\Component\HttpKernel;
use Symfony\Component\BrowserKit\Client as BaseClient;
class Client extends BaseClient
{
...
/**
* Converts the BrowserKit request to a HttpKernel request.
*
* #param DomRequest $request A DomRequest instance
*
* #return Request A Request instance
*/
protected function filterRequest(DomRequest $request)
{
$httpRequest = Request::create($request->getUri(), $request->getMethod(), $request->getParameters(), $request->getCookies(), $request->getFiles(), $request->getServer(), $request->getContent());
foreach ($this->filterFiles($httpRequest->files->all()) as $key => $value) {
$httpRequest->files->set($key, $value);
}
return $httpRequest;
}
...
}
You have to override method filterRequest to return kind of a request you want.
