Integration Testing

I’m using integration testing, with multiple sessions. For the typical
example, a module extends a session, like here:

http://weblog.jamisbuck.org/2006/3/9/integration-testing-in-rails-1-1

For my testing, I would like to emulate the web interface with ruby
objects. I’d like the test statements to look like

bob.goes_to_login
bob.goes_to_main_page
bob.main_window.click(photos(:photo_of_bob))
bob.main_window.menu.click(menus(:file))

I’m not clear on how I can get the structure above using modules,
methods and classes.

Any help appreciated!
