rspec测试失败

Question

I have a failing Rspec test, _pages_spec.rb. I am following Micheal Hartl's Rails Tutorial.

When I have the second "end" at line 83, all tests pass but one:

Failures:

Here is the code:

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

Can anyone find the problem?

Answer 1

User pages signup edit with valid information

Here's how it looks like:

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

It should be

User pages edit with valid information

ie

User pages
  |- edit
      |- with valid information

Currently edit is described under signup. That's not quite right.

I have the second "end" at line 83

It should be right after the line 53 rather than 83. ie right before describe "edit" do .

With consistent indentation you don't need to guess where to put matching end , it should be obvious from code.

Answer 2

The error message is telling you that the page does not have the selector '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: it { should have_selector('div.alert.alert-success', text:'Welcome') }`

Capybara has a nifty method called save_and_open_page that lets you inspect the HTML file that Capybara parses. Call this method and view the source to inspect the selector that is not working for you. If you are still having trouble, paste the HTML that corresponds to the selector in your question.

You should clean up the formatting of your code because it is very hard to read with the inconsistent spacing and indentation.
