ruby - 如何在纯 Ruby(无 Rails)中使用 Capybara？

Question

我试图让 Capybara 在一个简单的 Ruby 脚本中运行——即没有/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('/')

问题是，当我运行它时，我得到了这个错误:

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 

我做错了什么？

更多信息:

• Mac OS X 10.5
• ruby 1.8.6(2009-06-08 补丁级别 369)[universal-darwin9.0]
• capybara (0.3.9)

谢谢!

注意:根据 jnicklas 的评论，我尝试了这个，它更接近于新的 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

不幸的是，我仍然看到同样的错误:

NameError: uninitialized constant Capybara::Session

想法？

谢谢!

Answer 1

下面是一些似乎对我有用的东西:

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
