Thanks David, but could you explain me how should I use this before do
block in order to sign in an user? I am not a very experienced Rails
developer and I tried different things like:

13    before :each do
14      # @member = Factory.create(:member)
15      request.env['warden'].stub(:authenticate!) { double(Member) }
16      sign_in @member
17      @person = Person.new
18    end

which throws this error:

RuntimeError in 'PeopleController Methods should render form for a new
person on GET people#new'
Could not find a valid mapping for
/Library/Ruby/Gems/1.8/gems/devise-1.0.8/lib/devise/mapping.rb:49:in
`find_scope!'
/Library/Ruby/Gems/1.8/gems/devise-1.0.8/lib/devise/test_helpers.rb:
71:in `sign_in'
/Users/damselem/Documents/Harvard/WebDev/hv_club/spec/controllers/
people_controller_spec.rb:16:

Thanks David, and sorry for asking too much about this issue.
