ruby-on-rails - 为什么请求规范中没有 capybara ？

Question

使用 rspec 和 capybara 开发新的 Rails 3.2.9 应用程序。

我在 Gemfile 中有以下内容:

gem 'rspec-rails'
gem 'capybara'

以及 spec/spec_helper.rb 中的以下内容:

require 'rspec/rails'
require 'capybara/rspec'

在 spec/requests/asdf_spec.rb 中:

require 'spec_helper'
describe 'Asdf' do
  describe "GET /asdfs" do
    it "should list asdfs" do
      visit asdfs_path
    end
  end
end

此测试失败:

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)>'

所以看起来 Capybara 没有被加载。啊，为什么不呢？我觉得我之前已经做了十几次完全相同的事情......可能对一些愚蠢的事情感到茫然。

所以这是一个 capybara 版本 2 的变化。我找到了这个:

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

这解释了:

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.
