Question

我正在参加RoR教程。当所有的rspec测试都变成绿色时，我就无法让我的工作了。我运行bundle exec rspec spec /和四个测试，一个失败，出现此错误：

故障：

1）访问后，身份验证登录信息无效   另一页
 Failure/Error: it { should_not have_selector('div.alert.alert-error') }
   expected #has_selector?("div.alert.alert-error") to return false, got true
 # ./spec/requests/authentication_pages_spec.rb:25:in `block (5 levels) in <top (required)>'Finished in 7.2 seconds 62 examples, 1
失败

失败的例子：

rspec ./spec/requests/authentication_pages_spec.rb:25#Authentication   在访问另一页后登录无效信息

我的authentication_pages_spec.rb文件：

require 'spec_helper'

describe "Authentication" 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)) }
      it { should have_link('Settings',    href: edit_user_path(user)) }
      it { should have_link('Sign out',    href: signout_path) }
      it { should_not have_link('Sign in', href: signin_path) }



    describe "follower by signout" do
      before {click_link "Sign out"}
      it {should have_link('Sign in')}
      end
    end
  end

 describe "authorization" do

    describe "for non-signed-in users" do
      let(:user) { FactoryGirl.create(:user) }

      describe "in the Users controller" do

        describe "visiting the edit page" do
          before { visit edit_user_path(user) }
          it { should have_title('Sign in') }
        end

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

请确保您的sessions_controller.rb create动作定义如下：

def create      
    user = User.find_by(email: params[:email].downcase)
    if user && user.authenticate(params[:password])
        # If the user exists and they give a correct password,
        # sign the user in and redirect to the user's show page.
        sign_in user
        redirect_to user 
    else
        # Create an error message and re-render the signin form.
        flash.now[:error] = 'Invalid email/password combination'
        render 'new'
    end
end

注意flash.now。它与我们在本教程的其他部分中使用的flash不同。

失败/错误：它{should_not have_selector（＆＃39; div.alert.alert-error＆＃39;）}
