Ruby on rails 4 使用Rails 4和selenium web驱动程序，可以在Travis CI上使用Sauce Labs，但不能在本地使用

我正在填写一个开源Rails项目的规范，需要在浏览器中运行该应用程序以获取我的一些功能规范。我想在Travis CI上使用沙司实验室，但不必重写我的规范，也可以在本地使用沙司实验室，因为：

我不想在开发期间必须连接到互联网才能运行我的规范

使规范依赖于Sauce Labs将使贡献者不可能在不设置自己的Sauce Labs帐户和环境变量的情况下自行运行规范

---

我找不到详细说明此场景的文档。实现这一目标的最佳方式是什么？

对于那些有类似需求的人，我最后做的就是：

.travis.yml：

env:
  global:
    - secure: "encrypted sauce username"
    - secure: "encrypted sauce secret key"

addons:
  sauce_connect: true

before_install:
  # install the ed text editor which we use to append 
  # file contents to a specific line of another file
  - sudo apt-get install -y ed
  # appends contents of travis/Gemfile.travis to Gemfile
  - cat travis/Gemfile.travis >> Gemfile
  # adds contents of travis/rails_helper.rb.travis to line 12 of spec/rails_helper.rb
  - ed -s spec/rails_helper.rb <<< '12r travis/rails_helper.rb.travis'$'\nw'

group :test, :development do
  gem 'sauce', '~> 3.1.1'

  gem 'parallel_tests'
end

require 'sauce'
require 'sauce/capybara'

# change to "Capybara.default_driver = :sauce" to use sauce 
# for ALL feature specs, not just ones marked with "js: true"
Capybara.javascript_driver = :sauce

Sauce.config do |config|
  config[:browsers] = [
    ['Linux', 'Chrome', nil],
    # and other OS/browser combos you want to support...
  ]
end

  Sauce.config do |config|
    config[:browsers] = [
      ['Linux', 'Chrome', nil],
      # and other OS/browser combos you want to support...
    ]
  end
end

travis/rails\u helper.rb.travis：

end

require 'sauce'
require 'sauce/capybara'

Capybara.javascript_driver = :sauce

Sauce.config do |config|
  config[:browsers] = [
    ['Linux', 'Chrome', nil],
    # and other OS/browser combos you want to support...

end

env:
  global:

    - secure: "encrypted sauce secret key"
    - SAUCY: true

  # change to "Capybara.default_driver = :sauce" to use sauce

  Capybara.javascript_driver = :sauce

  Sauce.config do |config|
    config[:browsers] = [
      ['Linux', 'Chrome', nil],
      # and other OS/browser combos you want to support...
    ]
  end
end

更新（2014/11/25）： 最后，我在最终的解决方案中使用了稍微不同的配置。我不喜欢在行号处插入的脆弱性。我没有在单独的文件中包含特殊的酱汁，而是将特殊配置嵌套在条件中，这取决于环境变量

SAUCY

是否设置为true

通过这种方式，如果我选择与以下产品搭配，我也可以轻松地在当地使用酱汁：

SAUCY=true bundle install
SAUCY=true SAUCE_USERNAME=username SAUCE_ACCESS_KEY=access_key bundle exec rspec

我是酱汁宝石的维护者；我喜欢这个只在Travis身上使用酱汁的解决方案！[Sauce Gem Wiki]（）上有一个迷你指南，用于使用环境变量交换Sauce的输入和输出；在Travis上，可以使用“Travis”环境变量。
