Testing an AJAX call in phpunit / symfony, using client or crawler - ajax

Question

I want to test a conroller which generates a page with a field that changes dynamically with ajax.
Here is the code of ajax:
<script>
var $groupeCompetence = $('#requete_prestataire_groupeCompetence');
// When sport gets selected ...
$groupeCompetence.change(function() {
// ... retrieve the corresponding form.
var $form = $(this).closest('form');
// Simulate form data, but only include the selected sport value.
var data = {};
data[$groupeCompetence.attr('name')] = $groupeCompetence.val();
// Submit data via AJAX to the form's action path.
$.ajax({
url : $form.attr('action'),
type: $form.attr('method'),
data : data,
success: function(html) {
// Replace current position field ...
$('#requete_prestataire_competence').replaceWith(
// ... with the returned one from the AJAX response.
$(html).find('#requete_prestataire_competence')
);
// Position field now displays the appropriate positions.
}
});
});
</script>
How can I call this code from phpunit using client or crawler?
I tried :
$this->client->request(
'POST',
'/',
array('requete_prestataire[groupeCompetence]' =>2),
array(),
array(),
array('HTTP_X-Requested-With' => 'XMLHttpRequest',
));
But it doesn't work.
Thanks a lot !

I found the solution :
you have to disable validation, and send the form as it was generated :
$crawler = $this->client->request('GET', '/');
$form = $crawler->selectButton('requete_prestataire_Rechercher')->form();
$form['requete_prestataire[groupeCompetence]'] = 2;
$form['requete_prestataire[competence]']->disableValidation()->select(50);
$crawler = $this->client->submit($form);
