如何设置Rails角度项目来测试JS？

Question

我试图设置我的Rails角度项目，以提供JS测试。我几乎所有在谷歌上找到的东西都试过了：

• 因果报应 (原为种皮)
• 茉莉 + 茉莉花-无头-WebKit
• 茉莉石
• 其他一些教程

但我都失败了。我正在寻找一种以最无痛的方式运行单元和e2e测试的方法(它可以在卫队或Karma中运行，我不在乎，但它必须在后台自动运行)。

有没有人有一些很好的文章，有一个很好的例子，如何实现这一点？在我的研究中，我发现了这，但是IMHO是一个如何不这样做的例子。

我的实际Gemfile

source 'https://rubygems.org'

# Use Ruby 1.9.3 instead default Heroku's 1.9.2
# for development I suggest https://gist.github.com/1688857
ruby '1.9.3'

gem 'rails', '3.2.12'

# Use PostgreSQL, which is quite awesome, fast and easy
gem 'pg'

# Gems used only for assets and not required
# in production environments by default.
group :assets do
  gem 'sass-rails', '~> 3.2.3'
  gem 'bootstrap-sass', '~> 2.3.1'

  # I heard that you like Compass
  gem 'compass'

  # Angular.js
  gem 'angularjs-rails'
  gem 'angularjs-rails-resource'
  gem 'angular-ui-rails'

  # Assets should be minified before production
  gem 'uglifier', '>= 1.0.3'
end

gem 'jquery-rails'

# Serve static pages like a boss
gem 'high_voltage'

# Some user management will be nice
gem 'devise' # User management
# gem 'cancan' # And they privileges

# To use Jbuilder templates for JSON
gem 'jbuilder'

# Be fast and deadly as Puma
#gem 'puma'

# We need also some administration panel, don't we?
gem 'rails_admin'

# Some helpers
gem 'andand'

group :development do
  # IRb is ugly. Use Pry for the God's sake
  gem 'pry-rails'

  # Deploy with Capistrano
  # gem 'capistrano'
  # or Vlad the Deployer
  # gem 'vlad'

  # Why bother yourself with rerunning tests? Use Guard
  gem 'guard'
  gem 'guard-rspec'
  gem 'guard-spork'
  gem 'guard-livereload'
  gem 'guard-jasmine'
  gem 'rb-fsevent', require: false
  gem 'rb-inotify', require: false

  # Who like ugly error pages? We don't.
  gem 'better_errors'
  gem 'binding_of_caller'

  # Prettier documentation
  gem 'yard'
end

group :development, :test do
  # Use RSpec for testing
  gem 'rspec-rails', '~> 2.12.0'

  # Test JS using Jasmine
  gem 'jasmine'
  gem 'jasmine-headless-webkit'

  # Some DB table generator
  gem 'factory_girl_rails', '~> 4.1.0'

  # And fake data generator
  gem 'ffaker'
end

group :test do
  # Some Gherkins will be also good (to vodka of course)
  gem 'turnip', '~> 1.1.0'

  # Aww, an of course some web browser will be also apprised
  gem 'capybara', '~> 2.0.1'

  # Clean DB after tests
  gem 'database_cleaner'

  # Some nice matchers
  gem 'shoulda-matchers'

  # Extend your mocks
  gem 'bourne', '~> 1.2.1'

  # Coverage reports will be nice
  gem 'simplecov', require: false
end

PS: --如果我能以一种简单的方式创建覆盖率报告，那就太好了。

您可以使用茶匙，它运行您最喜欢的测试套件(默认为茉莉花)，并且它们有一个wiki可以与角集成。茶匙与资产管道集成，因此您可以将所有的角宝石抛入其中，并在生成的spec_helper.js中要求它们。

另一件很酷的事情是:他们也有一个护卫插件可用。

我感觉到了你的痛苦，我花了一些尝试和错误来让我的Rails应用程序运行所有的测试。最后，我使用Guard对规范、验收和javascripts进行了持续测试。这是我劳动的成果。

这是您需要包含的Gemfile片段。它具有守卫、茉莉、Rspec和萝卜所需的Gems。这个设置将与核磁共振和JRuby一起工作，我们对两者都进行了测试。

group :test, :development do
  # Guard
  gem 'guard-jasmine'
  gem "guard-bundler", ">= 1.0.0"
  gem "guard-rails", ">= 0.4.0"
  gem "guard-rspec", ">= 2.5.2"
  gem "rb-inotify", ">= 0.9.0", :require => false
  gem "rb-fsevent", ">= 0.9.3", :require => false
  gem "rb-fchange", ">= 0.0.6", :require => false

  # Rspec
  gem "rspec-rails", '~> 2.12.2'

  # Jasmine
  gem "jasmine", '~> 1.3.1'
  gem "jasminerice"
end

group :test do
  # Turnip
  gem "turnip", '~> 1.1.0'
  gem "capybara", '~> 2.0.3'
end

这是监视Rspec、Turnip和Jasmine以触发测试的完整Guardfile：

guard 'rspec' do
  watch(%r{^spec/.+_spec\.rb$})
  watch(%r{^lib/(.+)\.rb$})     { |m| "spec/lib/#{m[1]}_spec.rb" }
  watch('spec/spec_helper.rb')  { "spec" }

  # Rails 
  watch(%r{^app/(.+)\.rb$})                           { |m| "spec/#{m[1]}_spec.rb" }
  watch(%r{^app/(.*)(\.erb|\.haml)$})                 { |m| "spec/#{m[1]}#{m[2]}_spec.rb" }
  watch(%r{^app/controllers/(.+)_(controller)\.rb$})  { |m| ["spec/routing/#{m[1]}_routing_spec.rb", "spec/#{m[2]}s/#{m[1]}_#{m[2]}_spec.rb", "spec/acceptance/#{m[1]}_spec.rb"] }
  watch(%r{^spec/support/(.+)\.rb$})                  { "spec" }
  watch('config/routes.rb')                           { "spec/routing" }
  watch('app/controllers/application_controller.rb')  { "spec/controllers" }

  # Turnip features and steps
  watch(%r{^spec/acceptance/(.+)\.feature$})
  watch(%r{^spec/acceptance/steps/(.+)_steps\.rb$})   { |m| Dir[File.join("**/#{m[1]}.feature")][0] || 'spec/acceptance' }
end

guard :jasmine do
  watch(%r{spec/javascripts/spec\.(js\.coffee|js|coffee)$}) { 'spec/javascripts' }
  watch(%r{spec/javascripts/.+_spec\.(js\.coffee|js|coffee)$})
  watch(%r{spec/javascripts/fixtures/.+$})
  watch(%r{app/assets/javascripts/(.+?)\.(js\.coffee|js|coffee)(?:\.\w+)*$}) { |m| "spec/javascripts/#{ m[1] }_spec.#{ m[2] }" }
end

现在事情变得有点棘手。为了让茉莉花能够正确地加载AngularJS进行测试，我将角质层.下载到了spec/javascripts/support/angt-mocks.js目录。规范助手和jasmine使用它来运行AnguljarJS规范。

对于spec/ javascript /spec_helper.js.cof，请将其指向Rails应用程序javascript、角-mocks.js和所有javascript规范：

#=require ../../app/assets/javascripts/application
#=require ./support/angular-mocks
#=require_tree ./

对于Jasmine，spec/ javascript /support/jasmine.yml，配置将需要指向Rails应用程序javascript和角-mocks.js。以下是我们使用的内容，但为了简洁起见，删除了注释：

src_files:
  - assets/application.js
  - spec/javascripts/support/angular-mocks.js

stylesheets:
  - stylesheets/**/*.css

helpers:
  - helpers/**/*.js

spec_files:
  - '**/*[sS]pec.js'

src_dir:

spec_dir: spec/javascripts

所有设置就绪后，您只需运行bundle exec guard，所有测试都将运行，并由开发更改触发。

我写了一篇博客文章，介绍了使用默认的Jasmine在Rails应用程序上设置AngularJS单元测试的一个非常简单的方法。为了使事情顺利进行，只需进行一个小的代码更改，茉莉花团队已经接受了这一点。

http://pivotallabs.com/unit-testing-angularjs-using-jasmine/

简而言之：

在Gemfile中添加茉莉花和angularjs-rails

gem "angularjs-rails"
gem "jasmine", github: "pivotal/jasmine-gem"

安装宝石并运行茉莉花生成器

$ bundle install
$ rails g jasmine:install

在应用程序代码的其余部分之前，向application.js添加角

//= require angular
//= require_tree .

创建一个名为./spec/javascripts/helpers/angular_helpers.js的文件并添加这一行

//= require angular-mocks

现在，您可以在您的AngularJS目录中包含app/assets实现文件，并编写使用所提供的模拟的测试。当您升级angularjs-rails gem时，您将同时获得angular.js和angular-mocks.js的新版本。
