Items, Widget, and Gears controller spec examples

controller_specs.rb

# Client required that *all* methods for controllers are covered and 
# do not allow guest access.
#
# To remove code duplication, add controller macro, update test suite.
# Macro defaults to :html formatted requests and handles member vs collection (assumes :id)
# Note that we can specify methods, formats, params, etc. along the lines of:
#   it_should_block_access_to :index, :format => :json
#   it_should_block_access_to :something, :method => :post
#   it_should_block_access_to :index, :foo => :bar
