Rails3，Cucumber，Capybara，File upload =>坏内容体（EOFError）？ [英] Rails3, Cucumber, Capybara, File upload => bad content body (EOFError)?

问题描述

我很难获得简单的文件上传测试工作。我在Rugs 3.0.0上使用ruby 1.9.2与Cucumber和Capybara。

查看：

 <％= form_tag/ upload / create，：multipart => true do％> 
< label for =file>要上传的文件：< / label> 
<％= file_field_tagfile％> 
<％= submit_tag上传％> 
<％end％> 
  

Cucumber步骤：

 当/ ^我上传基本文件$ / do 
访问path_to（upload）
 path = File.join（:: Rails.root，somefile）
 attach_file（file，path）
 click_button（Upload）
 end 
  

$ b b

在我的控制器中，我已经注释掉除了以下内容：

  def create 
 file = params [ ：file] 
 end 
  

Gemfile片段：

  group：development，：test do 
＃使用规格测试
 gemZenTest，> = 4.3.3
 gemautotest
 gemrspec-rails，> = 2.0.0.beta.19，：git => git：//github.com/rspec/rspec-rails.git
 gemrspec，：git => git：//github.com/rspec/rspec.git
 gemrspec-core，：git => git：//github.com/rspec/rspec-core.git
 gemrspec-expectations，：git => git：//github.com/rspec/rspec-expectations.git
 gemrspec-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'＃所以你可以做然后显示页面
 gem'escape_utils'＃需要修复Cucumber  -  http： //crimpycode.brennonbortz.com/?p=42 
 end 
  

运行测试，我收到：

 （：:)失败的步骤$ b bad content body（EOFError）
< internal：prelude>：10：in'同步'
  

我很感激任何帮助或见解。谢谢。

解决方案

这证明是rack-test的问题，它可能不会是一个问题，更多的人采用Rails3和Ruby 1.9.x。

将rack-test升级到当前主分支修复了问题。
我不知道rack-test何时会将这些更改包括在gem中。

I'm having a hard time getting a simple file upload test working. I'm using Rails 3.0.0 on ruby 1.9.2 with Cucumber and Capybara.

View:

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

Cucumber Step:

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

In my controller, i have commented out everything except for:

def create
  file = params[:file]
end

Gemfile snippet:

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

When I try to run the test, I receive:

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

I appreciate any help or insight. Thanks.

解决方案

This turned out to be an issue with rack-test and it probably won't be a problem for most until more people adopt Rails3 and Ruby 1.9.x.

Upgrading rack-test to the current master branch fixed the problem. I'm not sure when rack-test will include these changes in the gem.
