Symfony how to validate an AJAX request
In my project, I have a part of my form that submits an AJAX request:
$.ajax({
url: '/bio_control/sample',
type: 'POST',
dataType: 'json',
data: {sample_number: $(input_field).val()},
});
Which activates the following controller method:
/**
* @Route("/bio_control/sample", name="get_bio_control_sample")
*/
public function getBioControlSampleAction(Request $request)
{
$sample_number = $request->request->get('sample_number');
/**
* Additional logic not shown for brevity.
*/
$user_id = $user->getId();
$response = array("code" => 100, "success" => true, "sample_number" => $sample_number, "sample_data" => $sample[0], "new_user" => false, "user_id" => $user_id);
return new JsonResponse($response);
}
I would like to be able to test this request in isolation, but I'm not sure how to write the request object.
So far, my first try:
public function testGetBioControlSample()
{
$helper = $this->helper;
$client = $this->makeClient();
$crawler = $client->request('POST', "/bio_control/sample", array(), array('sample_number' => 67655), array(
'CONTENT_TYPE' => 'application/json',
'HTTP_X-Requested-With' => 'XMLHttpRequest'
));
$this->assertStatusCode(200, $client);
}
Failed because it seems to be submitting the form (I get an error related to the form field, completely unrelated to a missing AJAX request).
Can anyone demonstrate how to write such a test correctly?

Does this URL require authentication?
I like to use LiipFunctionalTestBundle for my functional tests and they usually look like this:
<?php
declare(strict_types=1);
namespace Tests\Your\Namespace;
use Liip\FunctionalTestBundle\Test\WebTestCase;
class PostResourceActionTest extends WebTestCase
{
public function testShouldReturnResponseWithOkStatusCode(): void
{
$credentials = [
'username' => 'user',
'password' => 'pass'
];
$client = $this->makeClient($credentials);
$payload = ['foo' => 'bar'];
$client->request(
'POST',
'/the/url/',
$payload,
[],
['HTTP_Content-Type' => 'application/json']
);
$this->assertStatusCode(200, $client);
}
}
Perhaps the error you are getting is a login form asking for authentication?

The exact syntax I used to solve this problem was as follows:
public function testGetBioControlSample()
{
$helper = $this->helper;
$client = $this->makeClient();
$crawler = $client->request(
'POST',
"/bio_control/sample",
array('sample_number' => 67655),
array(),
array('HTTP_Content-Type' => 'application/json')
);
$JSON_response = json_decode($client->getResponse()->getContent(), true);
$this->assertStatusCode(200, $client);
$this->assertNotEmpty($JSON_response);
$this->assertEquals($JSON_response["code"], 100);
$this->assertEquals($JSON_response["success"], true);
$this->assertEquals($JSON_response["sample_number"], 67655);
}
I believe I don't need: 'HTTP_X-Requested-With' => 'XMLHttpRequest'
in the last argument of the array.
Also, I had the array('sample_number' => 67655)
wrong argument.
