Testing page title with Capybara 2.4 and rspec 3 and rails 4

Question

I am trying to test the title of my static pages in rails. I'm using Capybara 2.4.4 and rspec 3.

My test looks like the following static_pages_controller_spec.rb

require 'spec_helper'
require 'rails_helper'
describe StaticPagesController do
  describe "GET 'Index'" do
    it "should be successful" do 
      visit root_path
      response.should be_success
    end

    it "should have the right title" do
      visit root_path
      expect(page).to have_selector('title', 
                     :text => "Index",
                     :visible => false)
    end 
  end
end

The page does have the correct title set. The error I'm getting says the following

Failure/Error: expect(page).to have_selector('title',
       expected to find css "title" with text "Index" but there were no matches

Answer 1

I spent quite a few hours trying to figure it out as well.

Ultimately what worked was this

Install capybara as a gem

group :test do
  gem 'rspec'
  gem 'capybara'
end

and run bundle install

Add the following to the top of spec/spec_helper.rb

require 'capybara/rails'
require 'capybara/rspec'

Then inside the RSpec.configure, add the config.include Capybara::DSL

RSpec.configure do |config|
  .
  .
  .
  config.include Capybara::DSL
end

Then in your pages_controller_spec.rb , modify to use as follows.

Notice that I have included Capybara.ignore_hidden_elements = false

describe PagesController do
  render_views
  Capybara.ignore_hidden_elements = false

  describe "GET 'home'" do
    it "should be successful" do
      get 'home'
      response.should be_success
    end
    it "should have the right title" do
      get 'home'
      response.body.should have_xpath("//title",:text => "ROR")
    end
  end

end
