Sending a POST request with PHPUnit - php

Question

I have a symfony website, and Im trying to do some unit testing. I have this kind of test where I try to submit something:
<?php
namespace Acme\AcmeBundle\Tests\Controller;
use Symfony\Bundle\FrameworkBundle\Test\WebTestCase;
class HomeControllerTest extends WebTestCase {
public function testrandomeThings() {
$client = static::createClient();
$crawler = $client->request(
'POST',
'/',
array(
"shopNumber" => 0099,
"cardNumber" => 231,
"cardPIN" => "adasd"),
array(),
array());
}
but I dont think that the data Im sending is being received in the controler:
class HomeController extends Controller
{
public function indexAction()
{
var_dump($_POST);
die;
return $this->render('AcmeBundle:Home:index.html.twig');
}
}
the var_dump is actually returning me an empty array.
What am I missing to send information through my POST request?

Answer 1

$_POST is a variable filled by PHP and the symfony request is only created from this globals if called directly over http. The symfony crawler doesn't make a real request, it creates a request from the parameters supplied in your $client->request and executes it. You need to access this stuff via the Request object. Never use $_POST, $_GET, etc. directly.
use Symfony\Component\HttpFoundation\Request;
class HomeController extends CoralBaseController
{
public function indexAction(Request $request)
{
var_dump($request->request->all());
die;
return $this->render('CoralWalletBundle:Home:index.html.twig');
}
}
use $request->request->all() to get all POST parameters in an array. To get only a specific parameter you can use $request->request->get('my_param'). If you ever need to acces GET parameters you can use $request->query->get('my_param'), but better set query parameters already in the routing pattern.

I think you're trying to do this:
$client = static::createClient();
$client->request($method, $url, [], [], [], json_encode($content));
$this->assertEquals(
200,
$client->getResponse()
->getStatusCode()
);
You're putting your data (content) in as the params array but you want to put it in as the raw body content which is a JSON encoded string.
