如何在纯Ruby（没有Rails）中使用Capybara？

I'm trying to get Capybara running in a simple Ruby script -- i.e. without/outside of Rails. Here's the script:

我试图让Capybara运行在一个简单的Ruby脚本中 - 即没有/不在Rails之外。这是脚本：

require 'rubygems'
require 'capybara'
require 'capybara/dsl'

include Capybara

Capybara.current_driver = :selenium
Capybara.app_host = 'http://www.google.com'

visit('/')

The problem is that when I run this I get this error:

问题是，当我运行这个时，我收到此错误：

NameError: uninitialized constant Capybara::Session

at top level    in dsl.rb at line 52
method gem_original_require in custom_require.rb at line 36
method require  in custom_require.rb at line 36
at top level    in capybara_test.rb at line 3
method gem_original_require in custom_require.rb at line 31
method require  in custom_require.rb at line 31
at top level    in capybara_test.rb at line

What am I doing wrong?

我究竟做错了什么？

Note: Per the comment from jnicklas I tried this, which matches the new README more closely:

注意：根据jnicklas的评论我试过这个，它更接近地匹配新的README：

require 'rubygems'
require 'capybara'
require 'capybara/dsl'

Capybara.default_driver = :selenium
Capybara.app_host = 'http://www.google.com'

module MyCapybaraTest
  include Capybara

  def test_google
    visit('/')
  end
end

Unfortunately, I'm still seeing the same error:

不幸的是，我仍然看到同样的错误：

NameError: uninitialized constant Capybara::Session

Thoughts?

思考？

Thanks!

谢谢！

#1

Here's something that seems to work for me:

这似乎对我有用：

require 'rubygems'
require 'capybara'
require 'capybara/dsl'

Capybara.run_server = false
Capybara.current_driver = :selenium
Capybara.app_host = 'http://www.google.com'

module MyCapybaraTest
  class Test
    include Capybara::DSL
    def test_google
      visit('/')
    end
  end
end

t = MyCapybaraTest::Test.new
t.test_google

It goes to show that even incorrect documentation lives forever. The Capybara README used to recommend to include Capybara in the global namespace, this is a really bad idea, and messes up any number of random things. You should include Capybara in your own module or class and use that instead.

它表明，即使不正确的文档永远存在。 Capybara README曾经建议将Capybara包含在全局命名空间中，这是一个非常糟糕的主意，并且会乱搞任意数量的随机事物。您应该在自己的模块或类中包含Capybara并使用它。

Check out the README for current best practices.

Please check this CapybaraRspec101 example and fork it.

请检查此CapybaraRspec101示例并进行分叉。

It's a small example for acceptance tests on http://www.hi5.com using from scratch:
