Cacheable Flash 0.1.4 — Test Helpers

October 8, 2007 Brian Takita

This post was originally written by Brian Takita.

I just released Cacheable Flash 0.1.4. This version includes test helpers so you can easily test your cache messages. It works by allowing you to make assertions on the flash cookie.

Here is a test/unit example:

  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

Here is a rspec example:

  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

You can install Cacheable Flash by running:

ruby script/plugin install svn://rubyforge.org/var/svn/pivotalrb/cacheable_flash/trunk

See the Cacheable Flash blog post, Show Flash Messages on Cached Pages, and the README for more information.
