rspec测试失败

Question

我的Rspec测试_pages_spec.rb失败。 我正在关注Micheal Hartl的Rails教程。

当我在第83行有第二个“结束”时，所有测试都通过了，但只有一个：

Failures:

  1) User pages signup edit with valid information
     ←[31mFailure/Error:←[0m ←[31mit { should have_selector('div.alert.alert-suc
cess') }←[0m

Failed examples:

it with valid information ←[0m

这是代码：

require 'spec_helper'

describe "User pages" do

  subject { page }
  let (:base_title) {"Tom Gong's Sample App"}

  describe "profile page" do
    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', content: "#{base_title} | Sign up") }
  end
  describe "signup" 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
      describe "after submission" do
        before { click_button submit}
        it { should have_selector('title', text: 'Sign up') }
        it { should have_content('error') }
      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
    describe "after saving the user" do
      before { click_button submit }
      let(:user) { User.find_by_email('user@example.com') }
      it { should have_selector('title', text:user.name) }
      it { should have_selector('div.alert.alert-success', text:'Welcome') }
    end
  end
  describe "edit" do
    let(:user) { FactoryGirl.create(:user) }
    before { visit edit_user_path(user) }
    describe "page" do
      it { should have_selector('h1',     text: "Update your profile") }
      it { should have_selector('title',  text:"Edit user") }
      it { should have_selector('a', href: 'http://gravatar.com/emails') }
    end
    describe "with invalid information" do
      before { click_button "Save changes" }
      it { should have_content('error') }
    end
    describe "with valid information" do
      let(:new_name) { "New Name" }
      let(:new_email) { "new@example.com" }
      before do
        fill_in "Name",             with: new_name
        fill_in "Email",            with: new_email
        fill_in "Password",         with: user.password
        fill_in "Confirm Password", with: user.password
        click_button "Save changes"
    end

      it { should have_selector('title', text: new_name) }
      it { should have_selector('div.alert.alert-success') }
      it { should have_link('Sign out', href: signout_path) }
      specify { user.reload.name.should  == new_name }
      specify { user.reload.email.should == new_email }
    end
  end
end
end

谁能找到问题？

Answer 1

用户页面注册使用有效信息进行编辑

看起来是这样的：

User pages
  |- signup
      |- edit
          |- with valid information

它应该是

用户页面使用有效信息进行编辑

即

User pages
  |- edit
      |- with valid information

当前编辑在注册下描述。 那不是很正确。

我在第83行有第二个“结尾”

它应该在53行之后而不是83行之后。即在describe "edit" do 。

使用一致的缩进，您无需猜测匹配end ，这从代码中应该显而易见。

Answer 2

错误消息告诉您该页面没有选择器'div.alert.alert-success'. It looks like the error is related to this line: 'div.alert.alert-success'. It looks like the error is related to this line:它{应该具有_selector（'div.alert.alert-success'，文本：'Welcome'）}}

save_and_open_page有一个名为save_and_open_page的漂亮方法，可让您检查save_and_open_page解析的HTML文件。 调用此方法并查看源以检查对您不起作用的选择器。 如果仍然遇到问题，请在问题中粘贴与选择器相对应的HTML。

您应该清理代码的格式，因为空格和缩进不一致会很难阅读。
