Gem 集成测试失败，jQuery 未找到

Question

我有一个名为“fantastic”的 gem，里面有一个 dummy app 来测试。运行启用虚拟应用程序时，一切正常。

然而，当我运行测试时，单元测试工作正常，但集成测试 (Capybara + Poltergeist) 失败并显示消息：

Sprockets::FileNotFound: couldn't find file 'jquery' with type 'application/javascript'.

Checked in these paths:

/fantastic/spec/dummy/app/assets/images, /fantastic/spec/dummy/app/assets/javascripts, /fantastic/spec/dummy/app/assets/stylesheets, /fantastic/app/assets/javascripts, /fantastic/app/assets/stylesheets, /fantastic/vendor/assets/javascripts

我的一些文件：

fantastic.gemspec

# ...
s.add_development_dependency "capybara"
s.add_development_dependency "poltergeist"
s.add_development_dependency "jquery-rails"
# ...

spec/dummy/app/assets/javascripts/application.js

//= require jquery // Error is produced in this line
//= require jquery_ujs
//= require fantastic
//= require_tree .

问题是当运行ning rails server 一切正常，并且 jQuery 加载正确（我在浏览器的控制台）。

知道测试中发生了什么吗？

编辑

我尝试创建自定义 Capybara.app:

spec/spec_helper.rb

ENV["RAILS_ENV"] = 'test'
# Require dummy Rails app
require File.expand_path("../../spec/dummy/config/environment", __FILE__)

require 'database_cleaner'
require 'rspec/rails'
require 'capybara/rspec'
require 'capybara/poltergeist'

# Requires supporting ruby files with custom matchers and macros, etc,
# in spec/support/ and its subdirectories.
Dir["#{File.dirname(__FILE__)}/support/**/*.rb"].each {|f| require f}

require 'capybara/dsl'

Capybara.app = Rack::Builder.new do
  map "/spec/dummy/" { run Rails.application }
end.to_app

Capybara.register_driver :poltergeist do |app|
  Capybara::Poltergeist::Driver.new(app, {js_errors: false})
end
Capybara.javascript_driver = :poltergeist

RSpec.configure do |config|
  # 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
  config.infer_spec_type_from_file_location!
end

鉴于虚拟应用程序位于 spec/dummy/ 文件夹中。

这是我在运行测试

时遇到的错误

Failure/Error: expect(page).to have_content "Users" expected to find text "Users" in "Not Found: /users". (However, it was found 1 time using a case insensitive search.) # ./spec/features/record_updated_spec.rb:6:in `block (2 levels) in '

Answer 1

这就是最终解决问题的方法。

module Fantastic
  class Engine < ::Rails::Engine
    require 'jquery-rails' # <-- this line

    isolate_namespace Megaphone
  end
end
