require 'test/unit' require 'test/unit/assertions' 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') module Assertions def self.included(klass) %w(response selector tag dom routing model).each do |kind| require "action_controller/assertions/#{kind}_assertions" klass.send :include, const_get("#{kind.camelize}Assertions") end end def clean_backtrace(&block) yield rescue Test::Unit::AssertionFailedError => error framework_path = Regexp.new(File.expand_path("#{File.dirname(__FILE__)}/assertions")) error.backtrace.reject! { |line| File.expand_path(line) =~ framework_path } raise end end end module Test #:nodoc: module Unit #:nodoc: class TestCase #:nodoc: include ActionController::Assertions end end end
