Testing AJAX/XMLHttpRequest pages functionally in Symfony2

Question

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

Answer 1

For POST, PUT:

$crawler = $client->request('POST', '/foo/', array('param' => 'value'), array(),
array(
    'HTTP_X-Requested-With' => 'XMLHttpRequest',
));

For POST, PUT with raw JSON body:

$crawler = $client->request('POST', '/foo/', array(), array(), array(
    'HTTP_X-Requested-With' => 'XMLHttpRequest',
    'CONTENT_TYPE' => 'application/json',
), '{"param": "value"}');
