like above all the request from unit test will not in cons.REQUEST_SOURCE_TYPE.

so all the request will do not know whether come for user or from local neturon .

[baisen (song1)]

it is look like a throuble.

in resource2.py openstack generate the post methond base on the session,but it do not

pass the user-agent para.

 response = session.post(request.uri, endpoint_filter=self.service,
                                    json=request.body, headers=request.headers)

even in the session.py the function have allow to pass the user_agent para.like below.

 def request(self, url, method, json=None, original_ip=None,
                user_agent=None, redirect=None, authenticated=None,
                endpoint_filter=None, auth=None, requests_auth=None,
                raise_exc=True, allow_reauth=True, log=True,
                endpoint_override=None, connect_retries=0, logger=_logger,
                allow=None, client_name=None, client_version=None,
                microversion=None, microversion_service_type=None,
                **kwargs):

so even we set the usr-agent in the headers is also no use, because like below:
the request will rewrite the user-agent, which we have set it before this.

       if user_agent:
            headers['User-Agent'] = user_agent
        elif self.user_agent:
            user_agent = headers.setdefault('User-Agent', self.user_agent)
