为什么水豚在请求规格中不可用？ [英] Why is capybara not available in request specs?

问题描述

使用rspec和capybara开发新的Rails 3.2.9应用。

我在Gemfile中具有以下内容：

 宝石'rspec-rails'
宝石'水豚'
  

以及spec / spec_helper.rb中的以下内容：

 需要'rspec / rails'
需要'capybara / rspec'
  

并在spec / requests / asdf_spec.rb中：

 需要'spec_helper'
描述'Asdf'做
描述 GET / asdfs做
应该列出asdfs做
访问asdfs_path 
结束
结束
结束
  

此测试失败：

 失败/错误：访问asdfs_path 
 NoMethodError：
 ＃< RSpec :: Core :: ExampleGroup :: Nested_1 :: Nested_2 :: Nested_1：0x007fa7b68961a0>的未定义方法`visit'； 
＃./spec/requests/asdfs_spec.rb:19:in`top（必需）>'
   
 
 
所以看起来水豚没有被装上。阿克，为什么不呢？我觉得我之前已经做过十多次相同的事情了……可能是在愚蠢的事情上做空了。
解决方案
所以这是水豚第2版的更改。我发现了这一点：
 
 
 
  http://alindeman.github.com/2012/11/11/rspec-rails-and-capybara-2.0-what-you-need- to-know.html  
 
 
 
这说明：
 
 
 Upon升级到capybara 2.0后，在RSpec请求规范中，默认
不能使用  capybara  。而是创建了一种新的规格-
功能规格-供水豚使用。
 
 
 
要升级到水豚2.0，您将需要做一些事情：
 
 
 
 
 
将rspec-rails升级到2.12.0或更高版本
 
 
将使用水豚的所有测试从规格/要求移至规格/功能。 Capybara 
测试使用visit方法，通常针对页面进行断言。
 
 
 
 
 
Working on a new Rails 3.2.9 app with rspec and capybara.

I have the following in the Gemfile:
gem 'rspec-rails'
gem 'capybara'
and the following in spec/spec_helper.rb:
require 'rspec/rails'
require 'capybara/rspec'
and in spec/requests/asdf_spec.rb:
require 'spec_helper'
describe 'Asdf' do
  describe "GET /asdfs" do
    it "should list asdfs" do
      visit asdfs_path
    end
  end
end
This test is failing:
Failure/Error: visit asdfs_path
NoMethodError:
 undefined method `visit' for #<RSpec::Core::ExampleGroup::Nested_1::Nested_2::Nested_1:0x007fa7b68961a0>
# ./spec/requests/asdfs_spec.rb:19:in `block (4 levels) in <top (required)>'
So it looks like Capybara isn't getting loaded. Ack, why not? I feel like I've done this exact same thing a dozen times before... probably blanking on something stupid.
解决方案
So it was a capybara version 2 change. I found this:

http://alindeman.github.com/2012/11/11/rspec-rails-and-capybara-2.0-what-you-need-to-know.html

which explains:

  
Upon upgrading to capybara 2.0, capybara will not be available by
  default in RSpec request specs. Instead, a new type of spec--the
  feature spec--has been created for use with capybara.
  
  
To upgrade to capybara 2.0, you'll need to do a few things:
  
  

  
Upgrade rspec-rails to 2.12.0 or greater
  
Move any tests that use capybara from spec/requests to spec/features. Capybara 
  tests use the visit method and usually assert against page.
