Question

我不想继续讨论所有人，但我有另一个问题。我想我只是错过了一些非常简单的东西，但我无法找到它会是什么。我在第8章结束时进行了登录/上/下示例应用程序。但是当我运行测试时，我收到以下错误。

Failures:

  1) Aithentication signin with valid information followed by signout 
     Failure/Error: before { click_link "Sign Out" }

这是我的User_pages_spec

require 'spec_helper'

describe "User pages" do

  subject { page }

  describe "profile page" do
    let(:user) { FactoryGirl.create(:user) } #this was what I added
    before { visit user_path(user) }

    it { should have_content(user.name) }
    it { should have_title(user.name) }
  end

  describe "signup page" do
    before { visit signup_path }

    it { should have_content('Sign up') }
    it { should have_title(full_title('Sign up')) }
  end

  describe "signup page" do

    before { visit signup_path }

    let(:submit) { "Create my account" }

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

    describe "with valid information" do
      before do
        fill_in "Name",         with: "Example User"
        fill_in "Email",        with: "user@example.com"
        fill_in "Password",     with: "foobar"
        fill_in "Confirmation", with: "foobar"
      end

      it "should create a user" do
        expect { click_button submit }.to change(User, :count).by(1)
      end
    end

    describe "after saving the user" do
        before { click_button submit }
        let(:user) { User.find_by(email: 'user@example.com') }

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

和我的authentication_page_spec

require 'spec_helper'

describe "Aithentication" do

    subject { page }

    describe "signin page" do
        before { visit signin_path }

        it { should have_content('Sign in') }
        it { should have_title('Sign in') }
    end

    describe "signin" do
        before { visit signin_path }

        describe "with invalid information" do
            before { click_button "Sign in"}

            it { should have_title('Sign in') }
            it { should have_selector('div.alert.alert-error') }

            describe "after visiting another page" do
                before { click_link "Home" }
                it { should_not have_selector('div.alert.alert-error') }
            end
        end


    describe "with valid information" do
      let(:user) { FactoryGirl.create(:user) }
      before do
        fill_in "Email",    with: user.email.upcase
        fill_in "Password", with: user.password
        click_button "Sign in"
      end

      it { should have_title(user.name) }
      it { should have_link('Profile',     href: user_path(user), visible: false) }
      it { should have_link('Sign out',    href: signout_path) }
      it { should_not have_link('Sign in', href: signin_path) }

      describe "followed by signout" do
        before { click_link "Sign Out" }
        it { should have_link('Sign In') }
      end
    end
  end
end

这是我的_header，其中大部分失败来自我认为

<header class="navbar navbar-fixed-top navbar-inverse">
  <div class="navbar-inner">
    <div class="container">
      <%= link_to "sample app", root_path, id: "logo" %>
      <nav>
        <ul class="nav pull-right">
          <li><%= link_to "Home", root_path %></li>
          <li><%= link_to "Help", help_path %></li>
          <% if signed_in? %>
            <li><%= link_to "Users", '#' %></li>
            <li id="fat-menu" class="dropdown">
              <a href="#" class="dropdown-toggle" data-toggle="dropdown">
                Account <b class="caret"></b>
              </a>
              <ul class="dropdown-menu">
                <li><%= link_to "Profile", current_user %></li>
                <li><%= link_to "Settings", '#' %></li>
                <li class="divider"></li>
                <li>
                  <%= link_to "Sign out", signout_path, method: "delete" %>
                </li>
              </ul>
            </li>
          <% else %>
            <li><%= link_to "Sign in", signin_path %></li>
          <% end %>
        </ul>
      </nav>
    </div>
  </div>
</header>

感谢您的帮助，请告诉我您是否需要其他任何内容。

Answer 1

capybara通常搜索区分大小写，并搜索带有标签，名称或ID的字段。

在第一个测试案例中

<%= link_to "Sign out", signout_path, method: "delete" %>

  describe "followed by signout" do
    before { click_link "Sign Out" }
    it { should have_link('Sign In') }
  end

您在此处搜索的是Sign Out，其链接中包含Sign out。

关于第3个测试用例

let(:user) { User.find_by(email: 'user@example.com') }将此更改为

let(:user) { User.find_by_email('user@example.com') }

希望这能解决您的问题。

添加下拉菜单后，无法通过测试
