session = <webdriver.client.Session object at 0x7f20aefa2550>, url = <function url at 0x7f20aef3b668>, server_config = {'host': 'localhost', 'ports': {'http': ['8802']}}

    def test_duplicated_cookie(session, url, server_config):
        session.url = url("/common/blank.html")
        clear_all_cookies(session)
        create_cookie_request = {
            "cookie": {
                "name": "hello",
                "value": "world",
