測試頁面標題與水豚2.4和rspec 3和rails 4

Question

我想在rails中測試我的靜態頁面的標題。我使用的是水豚2.4.4和RSpec 3.

我的測試看起來如下 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 

頁面確實有正確的標題集。 我得到的錯誤說下面

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

Answer 1

我花了好幾個小時，試圖弄明白爲好。

最終什麼工作是這樣的

安裝水豚作爲寶石

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

和運行bundle install

添加以下規格的頂部/ spec_helper.rb

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

然後在RSpec.configure裏面添加config.include Capybara::DSL

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

然後在你的pages_controller_spec.rb，修改使用如下。

注意，我已經包括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
