Treat your sessions like models, not hashes. Intercession mixes a module into the session on each request, allowing you to nicely encapsulate (and test!) lots of user and session-specific behavior.
Check out this gist: gist.github.com/44506
Unit tests for your session model! Mix it in to a Hash and go to town:
def setup @session = Hash.new @session.extend Transient::Session end def test_session_user_lazily_loads_from_user_id assert_nil @session.user @session[:user_id] = users(:default).id assert_equal users(:default), @session.user end
Intercession works as a plugin or a gem. I've only used it as a plugin against Rails 2.2, though, so YMMV. If you install it as a plugin, it'll create you a stub session module in app/models/transient/session.rb. If you're using it as a gem, do it yourself. :)
As a plugin:
$ script/plugin install git://github.com/jbarnette/intercession.git
As a gem:
$ gem install intercession
If you're using Intercession as a gem, add it to your app's gem dependency mechanism.
