Multiple clients in user test is deprecated, still present in documentation #12961
Description
Symfony version(s) affected: 4.4.0
Description
After upgrading to Symfony 4.4.0 I got the following deprecation warning:
Calling "Symfony\Bundle\FrameworkBundle\Test\WebTestCase::createClient()" while a kernel has been booted is deprecated since Symfony 4.4 and will throw in 5.0, ensure the kernel is shut down before calling the method.
However, I do the same as in the documentation (https://symfony.com/doc/current/testing/insulating_clients.html), this also gives the same deprecation warning. There is no clear alternative, is the documentation outdated or is this a bug?
How to reproduce
class PagesTestCase extends WebTestCase {
...
public function setUp(): void {
parent::setUp();
...
// Create clients
self::$anonymousClient = self::createClient(array(), array(
'HTTPS' => true,
));
self::$userClient = self::createClient(array(), array(
'PHP_AUTH_USER' => self::get('anonymous')->getUsername(),
'PHP_AUTH_PW' => '***',
'HTTPS' => true,
));
self::$adminClient = self::createClient(array(), array(
'PHP_AUTH_USER' => self::get('testuser')->getUsername(),
'PHP_AUTH_PW' => '***',
'HTTPS' => true,
));
