RoR - 失败/错误：response.should have.selector，集成测试失败

Question

您好，我是 RoR 的新手，我正在尝试按照 Michael Hartl 的教程进行操作，但在集成测试期间遇到了问题。

我尝试了这里给出的解决方案，Why is Rspec saying "Failure/Error: Unable to find matching line from backtrace"?。但我仍然收到错误。

所以当我运行 $ rspec spec/ 时，它会显示，

1) LayoutLinks should have a Home page at '/'
 Failure/Error: response.should have.selector('title', :content => "Home")
 ArgumentError:
   wrong number of arguments (0 for 1)
 # ./spec/requests/layout_links_spec.rb:7:in `block (2 levels) in <top (required)>'

这是我的宝石清单：

webrat (0.7.1)
xpath (0.1.4)
ZenTest (4.6.2)
rspec (2.8.0, 2.0.1)
rspec-core (2.8.0, 2.0.1)
rspec-expectations (2.8.0, 2.0.1)
rspec-mocks (2.8.0, 2.0.1)
rspec-rails (2.8.1, 2.8.0, 2.0.1, 2.0.0.beta.18)
rubyzip (0.9.5)
sass (3.1.12)
sass-rails (3.2.3, 3.1.5)
capybara (1.1.2)
childprocess (0.3.0)
coffee-rails (3.2.1, 3.1.1)
coffee-script (2.2.0)
coffee-script-source (1.2.0)
cucumber (1.1.4)
cucumber-rails (1.2.1)
factory_girl (2.4.2)
factory_girl_rails (1.5.0)

这是我的 gem 文件：

gem 'therubyracer'
gem 'sqlite3'

group :development do
gem 'rspec-rails'
end

group :test do
gem 'webrat', '0.7.1'
gem 'rspec'
end

Gems used only for assets and not required
in production environments by default.
group :assets do
gem 'sass-rails',   '~> 3.2.3'
gem 'coffee-rails', '~> 3.2.0'

gem 'uglifier', '>= 1.0.3'
end

我猜这是 webrat/capybara 的问题，但我不知道如何解决这个问题。任何帮助都感激不尽。谢谢！

我对标题选择器和水豚有同样的问题。这段代码很适合我，试试吧：

within('head title') { page.should have_content "Home" }
