Example Template Markup
You can test your flash cookies by making assertions on the json of the “flash” cookie. Cacheable Flash provides test helpers which includes the flash_cookie method.
require "cacheable_flash/test_helpers" class TestController < ActionController::Base def index flash["notice"] = "In index" end end class ControllerTest < Test::Unit::TestCase include CacheableFlash::TestHelpers def setup @controller = TestController.new @request = ActionController::TestRequest.new @response = ActionController::TestResponse.new end def test_cacheable_flash_action get :index asset_equal "In index", flash_cookie["notice"] end end
require "cacheable_flash/test_helpers" class TestController < ActionController::Base def index flash["notice"] = "In index" end end describe TestController, "#index" do include CacheableFlash::TestHelpers it "writes to the flash cookie" do get :index flash_cookie["notice"].should == "In index" end end
