如何在纯Ruby（无Rails）中使用Capybara？ [英] How to use Capybara in pure Ruby (without Rails)?

问题描述

我试图让Capybara在简单的Ruby脚本中运行-即在Rails之外/之外。这是脚本：

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

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

include Capybara

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

visit('/')

问题是，当我运行此命令时，出现此错误：

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

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 

我在做什么错了？

更多信息：

• Mac OS X 10.5


• ruby​​ 1.8.6（2009-06-08补丁程序级别36 9）[universal-darwin9.0]


• 水豚（0.3.9）

谢谢！

注意：根据jnicklas的评论，我尝试过此操作，它与新的自述文件更紧密地匹配：

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

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

不幸的是，我仍然看到相同的错误：

Unfortunately, I'm still seeing the same error:

NameError: uninitialized constant Capybara::Session

有什么想法？

谢谢！

推荐答案

以下内容似乎对我有用：

Here's something that seems to work for me:

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
