module ActionController #:nodoc:
# In addition to these specific assertions, you also have easy access to various collections that the regular test/unit assertions
# can be used against. These collections are:
#
# * assigns: Instance variables assigned in the action that are available for the view.
# * session: Objects being saved in the session.
# * flash: The flash objects currently in the session.
# * cookies: Cookies being sent to the user on this request.
#
# These collections can be used just like any other hash:
#
# assert_not_nil assigns(:person) # makes sure that a @person instance variable was set
# assert_equal "Dave", cookies[:name] # makes sure that a cookie called :name was set as "Dave"
# assert flash.empty? # makes sure that there's nothing in the flash
#
# For historic reasons, the assigns hash uses string-based keys. So assigns[:person] won't work, but assigns["person"] will. To
# appease our yearning for symbols, though, an alternative accessor has been deviced using a method call instead of index referencing.
# So assigns(:person) will work just like assigns["person"], but again, assigns[:person] will not work.
#
# On top of the collections, you have the complete url that a given action redirected to available in redirect_to_url.
#
# For redirects within the same controller, you can even call follow_redirect and the redirect will be followed, triggering another
# action call which can then be asserted against.
#
# == Manipulating the request collections
#
# The collections described above link to the response, so you can test if what the actions were expected to do happened. But
# sometimes you also want to manipulate these collections in the incoming request. This is really only relevant for sessions
# and cookies, though. For sessions, you just do:
#
# @request.session[:key] = "value"
#
# For cookies, you need to manually create the cookie, like this:
#
# @request.cookies["key"] = CGI::Cookie.new("key", "value")
#
# == Testing named routes
#
# If you're using named routes, they can be easily tested using the original named routes methods straight in the test case.
# Example:
#
# assert_redirected_to page_url(:title => 'foo')
