和我的 authentication_pages_spec.rb

require 'spec_helper'

describe "Authentication" do

  subject { page }

  describe "signin page" do
    before { visit signin_path }
    it { should have_selector('h1', text: 'Sign in') }
    it { should have_selector('title', text: 'Sign in') }
  end

  describe "signin" do
    before { visit signin_path }
    describe "with invalid information" do

      it { should have_selector('title', text: 'Sign in') }
      it { should have_selector('div.alert.alert-error', text: 'Invalid') }
      describe "after visiting another page" do
        before { click_link "Home" }
        it { should_not have_selector('div.alert.alert-error') }

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

和 app/view/sessions/new.html.erb

<% provide(:title, "Sign in") %>
<h1>Sign in</h1>
<div class="row">
  <div class="span6 offset3">

您缺少描述块。使您的代码如下所示：

require 'spec_helper'

describe "Authentication" do
  subject { page }

  describe "signin page" do
    before { visit signin_path }
    it { should have_selector('h1', text: 'Sign in') }
    it { should have_selector('title', text: 'Sign in') }
  end

  describe "signin" do
    before { visit signin_path }
    describe "with invalid information" do
      before { click_button "Sign in" }
      it { should have_selector('title', text: 'Sign in') }
      it { should have_selector('div.alert.alert-error', text: 'Invalid') }
      describe "after visiting another page" do
        before { click_link "Home" }
        it { should_not have_selector('div.alert.alert-error') }
      end
    end

    # The following block is missing
    describe "with valid information" do
      let(:user) { FactoryGirl.create(:user) }
      before do
        fill_in "Email", with: user.email
        fill_in "Password", with: user.password
        click_button "Sign in"
      end

      it {should have_selector('title', text: user.name) }
      it {should have_link('Profile', href:user_path(user))}
      it{should have_link('Sign out',href: signout_path)}
      it{should_not have_link('Sign in',href: signin_path)}
     end
  end
end

Capybara 通常visit会先让你使用它的方法，然后才会让你使用它的fill_in方法。您忘记了将最终before块包装在一个describe块中，就像我在上面所做的那样，因此 before 块中的代码实际上覆盖了使用 visit 方法的前一个 before 块。所以这就是你有这个问题的原因。通过将最后一组断言包装在描述块中，您可以解决问题。

看起来事情在 1) 中开始出错，我相信这实际上是在 spec/requests/user_pages_spec.rb 文件中处理的。你能张贴你在那里的东西吗？此外，根据您在教程中的位置，您可能会丢失一些 authentication_pages_spec.rb 文件，因为http://ruby.railstutorial.org/chapters/sign-in-sign-out#sec-下的清单 8.6 signin_tests有工厂女孩调用和以下由描述块包围的“it”子句。
