== DESCRIPTION:

An rspec custom matcher to assert Rails action and fragment caching.

== FEATURES/PROBLEMS:

* Assert fragment caching with custom keys
* Assert action caching by URL
* Works only with memcached backend
* There are unresolved issues with the :format URL parameter (.xml, .json, ...)

== SYNOPSIS:

In test.rb turn on caching and set cache_store to memcache:

config.action_controller.perform_caching             = true
config.cache_store = :mem_cache_store


In spec_helper.rb, add into the config block:

config.include(CachingMatcher)
config.before { ActionController::Base.cache_store.clear }


In RSpec Controller Tests:

lambda {
   get :index
}.should be_cached(controller, :action => 'index')

lambda {
    get :edit, :id => 5
}.should_not be_cached(controller, :action => 'edit', :id => 5)

lambda {
    delete :destroy, :id => 5
}.should expire(controller, :action => 'index')

should_not expire is also available.

== REQUIREMENTS:

* memcached backend

== INSTALL:

* gem install caching_matcher
