Michael Hartl のRails 3 チュートリアルに従おうとしていますが、他の場所で説明されていないエラーが発生しています。セクション 9.2.1で、サインインしていないユーザーがプロファイル ページを更新しようとしている場合にテストを実行しようとすると、エラーが発生します。

describe "submitting to the update action" do
  before { put user_path(user) }
  specify { response.should redirect_to(signin_path) }
end

私が得ているエラーは、「未定義のローカル変数またはメソッド 'response' for # (NameError)」です。これは「bundle exec rspec spec/」に対する応答です。問題のある行をコメントアウトすると、すべてのテストがインスタンス化されてパスします。「response」を「response.body」や「page」などに置き換えてみましたが、どちらも役に立たないようです。

チュートリアルを進めていくと、同様のブロックが問題なく通過するため、問題が何であるかはわかりません。

エラーの全文は次のとおりです。

どこかのタイプミスではないと確信していますが、ここに問題のあるファイル (authentication_pages_spec.rb) があります。(have_title() は、明らかに have_selector('title',...) が有効な構文ではなくなったため、エラーを修正するためにここで見つけたメソッドです。)

require 'spec_helper'

  subject { page }

実行しているカピバラのバージョンは何ですか?

$ bundle exec gem list | grep capybara

バージョンを実行している場合は>= 2.0、Gemfile をもう一度見て、バージョンがチュートリアルと同じであることを具体的にマークする必要があります ( 1.1.2)。

Gemfile

group :test do
  gem 'capybara', '1.1.2'
end

どうしても最新バージョンを使用したい場合は、次のStackOverflow Q&A で説明されているように、いくつかの変更を加える必要があります。

アップデート

さて、あなたは自分自身を蹴るつもりですが、レポを複製して同じエラーが発生した後、問題は明らかです (構文の強調表示はあなたの友人です):

spec/requests/authentication_pages_spec.rbの77 行目:

specify ( response.should redirect_to(signin_path) )

そのはず：

specify { response.should redirect_to(signin_path) }

それを修正した後、テストは成功します。
