symfony2 phpunit - functional testing error (host_with_path)

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.

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.
