Laravel Persist Test Session ID Between Controller Calls

TestCase.php

<?php

class TestCase extends Laravel\Lumen\Testing\TestCase
{

    /**
     * Inject session ID into request, so api can persist on session
     */
    public function call($method, $uri, $parameters = [], $cookies = [], $files = [], $server = [], $content = null)
    {
        $session_id = session()->getId();
        $session_cookie = [session()->getName() => $session_id];

        // set session_id cookie for persistent test calls
        $cookies = array_merge($cookies, $session_cookie);
        parent::call($method, $uri, $parameters, $cookies, $files, $server, $content);
    }

}

This is awesome! Thanks
