The "new" authorization does not work in the tests, who faced it?

Question

symfony

In the fifth version, the method was delivered
$this->client->loginUser($user);

. As I understand it, it authorizes through cookies / session.
Amazing. But I don't have sessions.

Authorization by token through headers
HTTP_AUTHORIZATION' Bearer token

It turns out that $this->client->loginUser is generally useless?
And you need to generate a token and shove it into this client ...
