Testing AJAX/XMLHttpRequest pages functionally in Symfony2

Question

Is it possible to simulate/make an XMLHttpRequest request (ajax) in symfony2 tests?

Answer 1

The Request#isXmlHttpRequest() method simply checks if the X-Requested-With header is equivalent to XMLHttpRequest. If that's the method you're using to determine if a request is an ajax call, then you can simulate the behavior in the test client by adding the appropriate header to the request:

class FooFunctionalTest extends WebTestCase
{
    $client = static::CreateClient();
    $crawler = $client->request('GET', '/foo/', array(), array(), array(
        'X-Requested-With' => 'XMLHttpRequest',
    ));
    // ...
}
