rspec users - Sep 2008 - How to unit test code that connects to the external resources?

By external resources, I mean, the code start a http connection and GET xmls
from the url specified. I will definitely not rely my unit test on an
external url or anything like that. But how do I unit test the method? I
mean, I can basically mock the Net::HTTP, but then the test will pretty much
be like the method itself, except all the calls will be replaced by stub! or
should_receive.

I made this method as simple as possible. There is no *if* statements or
loop in the method, should I just NOT test this one?

Thanks for any ideas

def run
        url = URI.parse(run_path)
        http = Net::HTTP.new(url.host, url.port)
        http.use_ssl = use_ssl_for_run
        http.start {
            req = Net::HTTP::Get.new run_path
            req.basic_auth self.class.user, self.class.password
            @response = http.request(req)
        }
    end

run_path and use_ssl_for_run are both instance methods. run
