rspec users - May 2010 - RSpec newb - why is my negative test not passing?

Why won''t this test work?

I am trying to use RSpec to drive a negative test where my code will
throw an exception which it does however, the test does not pass.  It
fails due to my exception.  However, I am using should
raise_exception:
-----------------------

describe "Making non-existent url tiny" do

  it "should raise exception" do
    url = "tttttt.dddddd"
    exception_new = Exception.new "Test URL Error"
 
TinyUrlService.should_receive(:get).with(url).and_raise(exception_new)

    TinyUrlService.make_tiny(url).should raise_exception
  end
end

==========================================
Here is the code under test:
-------------------------------------
require ''httparty''

class TinyUrlService
  class InvalidUrl < Exception
    def intialize original_e
      super original_e.message
    end
  end

  include HTTParty

  base_uri ''tinyurl.com''

  def self.make_tiny (targetUrl)
     return get(''/api-create.php'', :query =>{:url =>
validate_url(targetUrl)})
  end

  private
  def self.validate_url(tiny_url)
    get(tiny_url)
    return tiny_url
  rescue Exception => e
    raise InvalidUrl.new(e)
  end

end

====================================Here is the exception reported:


TinyUrlService::InvalidUrl: Test URL Error
../lib/tiny_url_service.rb:23:in `validate_url''
../lib/tiny_url_service.rb:15:in `make_tiny''
/Users/johnferguson/ruby/flitter/specs/tiny_url_spec.rb:11:
-e:1:in `load''

Thanks, next time I''ll read the documentation with more attention to
what is written there.  It works as you said and as is documented.
