Assets are not loaded during capybara/rspec spec - ruby-on-rails

Question

I'm using rspec, capybara and launchy to test my web application.
Here's my spec:
require 'spec_helper'
describe "Routes" do
describe "GET requests" do
it "GET /root_path" do
visit root_path
page.should have_content("All of our statuses")
click_link "Post a New Status"
page.should have_content("New status")
fill_in "status_name", with: "Jimmy balooney"
fill_in "status_content", with: "Oh my god I am going insaaaaaaaaane!!!"
click_button "Create Status"
page.should have_content("Status was successfully created.")
click_link "Statuses"
page.should have_content("All of our statuses")
page.should have_content("Jimmy balooney")
page.should have_content("Oh my god I am going insaaaaaaaaane!!! ")
save_and_open_page
end
end
end
My .rspec
--color
--order default
and my spec_helper.rb:
# This file is copied to spec/ when you run 'rails generate rspec:install'
ENV["RAILS_ENV"] ||= 'test'
require File.expand_path("../../config/environment", __FILE__)
require 'rspec/rails'
require 'rspec/autorun'
require 'capybara/rspec'
# Requires supporting ruby files with custom matchers and macros, etc,
# in spec/support/ and its subdirectories.
Dir[Rails.root.join("spec/support/**/*.rb")].each { |f| require f }
# Checks for pending migrations before tests are run.
# If you are not using ActiveRecord, you can remove this line.
ActiveRecord::Migration.check_pending! if defined?(ActiveRecord::Migration)
RSpec.configure do |config|
# ## Mock Framework
#
# If you prefer to use mocha, flexmock or RR, uncomment the appropriate line:
#
# config.mock_with :mocha
# config.mock_with :flexmock
# config.mock_with :rr
config.before(:suite) do
DatabaseCleaner.strategy = :transaction
DatabaseCleaner.clean_with(:truncation)
end
config.before(:each) do
DatabaseCleaner.start
DatabaseCleaner.clean
end
config.after(:each) do
DatabaseCleaner.clean
end
# Remove this line if you're not using ActiveRecord or ActiveRecord fixtures
config.fixture_path = "#{::Rails.root}/spec/fixtures"
# If you're not using ActiveRecord, or you'd prefer not to run each of your
# examples within a transaction, remove the following line or assign false
# instead of true.
config.use_transactional_fixtures = true
# If true, the base class of anonymous controllers will be inferred
# automatically. This will be the default behavior in future versions of
# rspec-rails.
config.infer_base_class_for_anonymous_controllers = false
# Run specs in random order to surface order dependencies. If you find an
# order dependency and want to debug it, you can fix the order by providing
# the seed, which is printed after each run.
# --seed 1234
config.order = "random"
end
If you look back at my spec, you'll see a rspec spec that uses capybara to browse my application, and finishes by calling the launchy gem's save_and_open_page method to open this final page in a browser for a human to look at. At this final page, however, there is no javascript or css displayed, just pure HTML.
Does anyone have any ideas why this would be? I want to test javascript, and would prefer it if all assets were loaded.

Answer 1

Inside config.before(:suite) do
add:
%x[bundle exec rake assets:precompile]
to precompile your Rails assets then in your test.rb environment file add:
config.action_controller.asset_host = "file://#{::Rails.root}/public"
config.assets.prefix = 'assets_test'
to point to the location of the precompiled assets. Now you can use assets when you run Capybara. Note: make sure if you are using git to ignore that new folder.

Answer 2

You can just add to test.rb:
config.assets.compile = true
