Rails fragment cache testing with RSpec

Question

I feel like this is a not-so-much documented topic, at least I\'ve had a lot of trouble finding our about the best practices here.

I\'m fragment caching in the view usin

Answer 1

Here is what I've used in my specs with caching enabled in my config/environments/test.rb

require 'spec_helper'
include ActionController::Caching::Fragments

describe 'something/index.html.erb' do
  before(:each) do 
    Rails.cache.clear
    render
  end
  it 'should cache my fragment example' do
    cached_fragment = Rails.cache.read(fragment_cache_key(['x', 'y', 'z']))
    cached_fragment.should have_selector("h1")
  end
end
