I had the same problem and finally fixed.
The solution is to explicitly require the 'jquery-rails' gem in the
dummy config/application.rb file, so Sprockets can add the jquery
assets in the assets.path.
In test/dummy/config/application.rb
require File.expand_path('../boot', __FILE__)
# Pick the frameworks you want:
# require "active_record/railtie"
require "action_controller/railtie"
require "action_mailer/railtie"
require "active_resource/railtie"
require "rails/test_unit/railtie"
require "sprockets/railtie"
# Auto-require default libraries and those for the current Rails
environment.
Bundler.require :default, Rails.env
require "coffee"
require "jquery-rails" # this should be auto-included with the
Bundler.require :default, Rails.env, but it's not happening
module Dummy
class Application < Rails::Application
# ...
end
end
Same with other gems that have assets that should be auto-loaded by
Sprockets.
Hope this helps.
