Capybara, Rspec, Rails assets pipeline

A clean workaround for running capybara tests on Rails with assets pipeline enabled.

Original: teamcapybara/capybara#500 (comment)

capybara.rb

# environments/capybara.rb

Dummy::Application.configure do
  config.serve_static_assets = true
  config.static_cache_control = "public, max-age=3600"

  config.assets.compress = true
  config.assets.compile = false

  config.assets.precompile += %w(email.css)

  config.assets.digest = true
  config.assets.prefix = "/capybara_test_assets"
end

request_helper.rb

# spec/request_helper.rb

ENV["RAILS_ENV"] = 'capybara'

RSpec.configure do |config|
  config.before(:suite) do
    %x[bundle exec rake assets:precompile]
  end
end

You can save some seconds if you avoid to boot the rails environment twice:

config.before(:suite) do
  Rails.application.load_tasks
  Rake::Task["assets:precompile"].invoke
end
