RSpec helpers for testing page and action caching in Rails

RSpec Rails Caching

Provides a cache store for recording and matchers for testing cache events in Rails controller tests.

Installation

Add this line to your application's Gemfile:

gem 'rspec-rails-caching'

And then execute:

$ bundle

Or install it yourself as:

$ gem install rspec-rails-caching

Usage

Set config.action_controller.perform_caching = true in config/environments/test.rb

This gem captures the actual cache events for each request. In a controller example group, use a proc or a lambda around the action for matching:

describe WidgetsController, type: :controller do
  it "should cache the show action" do
    ->{ get :show, id: 123 }.should cache_page('/widgets/123')
  end

  it "should expire the update action" do
    ->{ put :update, id: 123 }.should expire_page('/widgets/123')
  end
end

Available matchers:

• cache_page / expire_page
• cache_fragment / expire_fragment
• cache_action / expire_action
