ruby-on-rails - Rails チュートリアルの RSpec エラー (User_Pages_Spec ch. 9.1.1)

Question

私は Hartl の Rails チュートリアルに取り組んでおり、9.1.1 の一部として最初のテストで行き詰まっています。user_pages_spec.rb、users_controller.rb、routes.rb、edit.html.erb、および application_controller.rb ファイルを調べましたが、何が問題なのかわかりません。

ターミナルで次の 3 つのエラーが発生します。

Ryans-MacBook-Air-3:tutorialapp rlhinchey$ bundle exec rspec spec/requests/user_pages_spec.rb -e "edit page"

テストが edit.html.erb ファイルを認識していないように見えますか? 私はこれに慣れていないので、おそらく完全に間違っています。どんな助けでも大歓迎です！

ここでこの回答を見つけました: Michael Hartl による Ruby on Rails チュートリアル。第 9.1 章の失敗したテスト

_header.html.erb ファイルを変更して、「#」を「users_path」に更新すると、全体が緑色に点灯しました。

Header.html ファイル:

ユーザーページの仕様:

describe "User pages" do

  subject { page }

    let(:user) { FactoryGirl.create(:user) }
    before { visit user_path(user) }

    it { should have_selector('h1',    text: user.name) }
    it { should have_selector('title', text: user.name) }
  end

describe "signup page" do
    before { visit signup_path }

    it { should have_selector('h1',    text: 'Sign up') }
    it { should have_selector('title', text: full_title('Sign up')) }
end

describe "signup" do

    before { visit signup_path }

    describe "with invalid information" do
        it "should not create a user" do
            expect { click_button "Create my account"}.not_to change(User, :count)
        end

it "should create a user" do
        expect do
          click_button "Create my account"
         end.to change(User, :count).by(1)

        it { should have_selector('div.alert.alert-success', text: 'Welcome') }
        it { should have_link('Sign out') }
        end

  end
end

Answer 2

訪問したページが正しくないようです

このコードをdescribe "page"セクションにドロップすると

it { should == '' }

エラー メッセージには、実際にアクセスされているページが表示されます。これにより、問題がどこにあるかの手がかりが得られます。これは、レンダリングされているページの html を確認するだけの便利な方法だと思います。
