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.
