How to set some data in session in functional test?

[shubaivan]

I use "liip/functional-test-bundle": "~1.8", and "symfony/symfony": "~3.4", and for my functional test I want set some data in session,but after set data in action, with the same key, I had null. Mytest class extends from extends WebTestCase

this is how I set data in test method

    $session = $this->container->get('session');
    $session->set('test', 2);

    $this->getClient()->request(
        Request::METHOD_GET,
        $routing
    );

config_test.yml

framework:
test: ~
session:
    storage_id: session.storage.mock_file
    name: "MOCKSESSID"
profiler:
    collect: false

and in action

public function getEntityAction()
{
    $test = $this->get('session')->get('test');

variable $test equal null

Someone had the same question in #383.

I think that the test should follow the same path than the one used by visitors. So you'll test that the data is wrote in session and readen later.

I think the main mistake here is forgetting that $this->container is NOT the same as $client->getContainer(): the Client spuns a completely separated, new container, and depending on how you use the session, you may not find the same stuff in both of them.

@Jean85 Do you remember if $this->getContainer() returns the container of the real application?

@alexislefebvre yes you get a real container, but it's not the same instance as $client->getContainer(); it's separated do avoid collisions or issues while testing through the client.

[alexislefebvre]

@shubaivan Did you try to use the client's container?

It may work with something like this:

$client = $this->makeClient();
$client->getContainer()->set('test', 2);
$crawler = $client->request('GET', '/contact');
