Facebooker talk - Dec 2008 - Getting a test working

A couple of months ago I forked facebooker and pushed a bunch of
patches I''ve written for work to the fork. Today I finally had some
time to write tests so I can submit the patches to core.

This is my first time working with test_unit and I''m having some
trouble getting the very first test I''m trying to write working.

The patch I''m writing the test for is to fix a caching bug with
events. A similar patch was pushed to core a few days ago but it only
fixed @user.events and not @session.events.

The patched version is:
session.rb

    def events(options = {})
      @events ||= {}
      @events[options.to_s] = post(''facebook.events.get'',
options) do |response|
        response.map do |hash|
          Event.from_hash(hash)
        end
      end
    end

The test I''m trying to get working is:
session_test.rb

  def test_events_caching_honors_params
    expect_http_posts_with_responses(example_events_get_xml)
    Facebooker::Event.expects(:from_hash)
    @session.events
    Facebooker::Event.expects(:from_hash)
    @session.events(:eids => "1,2")
    Facebooker::Event.expects(:from_hash).never
    @session.events(:eids => "1,2")
  end

When I run the test I get the following error:
test_events_caching_honors_params(SessionTest):
RuntimeError: Element events_get_response not found in     <?xml
version="1.0" encoding="UTF-8"?>
    <auth_createToken_response xmlns="http://api.facebook.com/1.0/"

    ./test/../lib/facebooker/logging.rb:27:in `log_fb_api''
    ./test/../lib/facebooker/session.rb:497:in `post''
    ./test/../lib/facebooker/session.rb:201:in `events''
    test/session_test.rb:141:in `test_events_caching_honors_params''

I''ve been trying to get this work for over an hour now. It seems that
@session.events works fine but when I call @session.events(:eids =>
"1,2") I get the error above.

Any idea where I might be going wrong?

Thanks!

Somehow the wrong response XML is being sent. I would try breaking  
that up into 3 tests and try to trace down where that XML is coming  
from.
