Rails3,Cucumber,Capybara,文件上传=>内容正文(EOFError)？

Question

我很难让简单的文件上传测试工作.我在使用Cucumber和Capybara的ruby 1.9.2上使用Rails 3.0.0.

视图:

<%= form_tag "/upload/create", :multipart => true do %>
  <label for="file">File to Upload:</label>
  <%= file_field_tag "file" %>
  <%= submit_tag "Upload" %>
<% end %>

黄瓜步骤:

When /^I upload the basic file$/ do  
  visit path_to("upload")
  path = File.join(::Rails.root, "somefile") 
  attach_file("file", path)
  click_button("Upload")
end

在我的控制器中,除了:

def create
  file = params[:file]
end

Gemfile片段:

group :development, :test do
  # testing with specs
  gem "ZenTest", ">= 4.3.3"
  gem "autotest"
  gem "rspec-rails", ">= 2.0.0.beta.19", :git => "git://github.com/rspec/rspec-rails.git"
  gem "rspec", :git => "git://github.com/rspec/rspec.git"
  gem "rspec-core", :git => "git://github.com/rspec/rspec-core.git"
  gem "rspec-expectations", :git => "git://github.com/rspec/rspec-expectations.git"
  gem "rspec-mocks", :git => "git://github.com/rspec/rspec-mocks.git"
  # cucumber stuff
  gem 'capybara'
  gem 'database_cleaner'
  gem 'cucumber-rails'
  gem 'cucumber'
  gem 'spork'
  gem 'launchy'    # So you can do Then show me the page
  gem 'escape_utils' # needed to fix Cucumber - http://crimpycode.brennonbortz.com/?p=42
end

当我尝试运行测试时,我收到:

(::) failed steps (::)
bad content body (EOFError)
<internal:prelude>:10:in `synchronize'

我感谢任何帮助或见解.谢谢.

事实证明，这是机架测试的一个问题，并且在更多人采用 Rails3 和 Ruby 1.9.x 之前，对于大多数人来说这可能不会成为问题。

将rack-test升级到当前的master分支解决了这个问题。我不确定机架测试何时会在 gem 中包含这些更改。
