我正在为个人计费构建一个设置屏幕。控制器/视图位于 Admin 命名空间中。

当在没有 :js => true 的情况下运行第一个测试时，我遇到了一个失败，我认为这是因为链接不能作为它的帮助器工作，它使用 js 脚本来构建一组嵌套的字段（基于 Railscasts单个表单，多个表 - 嵌套属性）。

Failures:

  1) Patient Setup create patient bill heading - with extended details -with valid data
     Failure/Error: fill_in "Extended Bill Heading", :with => 'Regular Registration'
     Capybara::ElementNotFound:
       cannot fill in, no text field, text area or password field with id, name, or label 'Extended Bill Heading' found
     # (eval):2:in `fill_in'
     # ./spec/requests/admin/patient_setup_pages_spec.rb:52:in `block (4 levels) in <top (required)>'

Finished in 0.83047 seconds
3 examples, 1 failure, 2 pending

但是当我使用 :js = true 时，我遇到了一个失败，这似乎来自登录，运行时无效的用户/密码在屏幕上闪烁。

在此处输入图像描述

Failures:

     Failure/Error: click_link 'System'

这是支持这一切的代码。

spec/requests/admin/patient_setup_spec.rb

require 'spec_helper'

feature 'Patient Setup' do

  let!(:ci_user) { FactoryGirl.create(:user, 
                                       name: "configuration engineer", 
                                       password: "password",
                                       password_confirmation: "password"
                                     ) }
  let!(:admin_role) { FactoryGirl.create(:admin_role) }
  let!(:assignment) { FactoryGirl.create(:assignment, 
                                         :role => admin_role, 
                                         :user => ci_user 
                                         ) } 

  before do 
    visit login_path
    fill_in "Name", with: "configuration engineer"
    fill_in "Password", with: "password"
    click_button "Login"
    save_and_open_page
    click_link 'System'
    click_link 'Patient Setup'
  end

  describe "create patient bill heading" do
    before do
      click_link 'New Bill Heading'
      fill_in 'Bill heading', :with => 'Consultation' 
      fill_in 'Abbreviation', :with => "CON"       
    end

    context "- no extended details" do
      pending

      scenario "- with valid data" do
        pending
        click_button 'Create Patient bill heading' 
        page.should have_content('Patient Bill Heading created.')
      end
    end

    context "- with extended details", :js => true do #(without :js => true 1st error)
      before do
        # save_and_open_page
        click_link "Extended Bill Heading"
        # save_and_open_page        
      end

      scenario "-with valid data" do
        save_and_open_page
        fill_in "Extended Bill Heading", :with => 'Regular Registration'
      end
    end

  end
end

这是我的出厂设置。

spec/factories.rb

FactoryGirl.define do

  # Users, Roles
  factory :user do
    name     "Joesephine Bloggs"
    password "testmenow"
    password_confirmation "testmenow"
  end

  factory :admin, :class => User do
    sequence(:name) { |n| "Administrator-#{n}" }
    password "adminiam"
    password_confirmation "adminiam"
    after(:create) do |user|
      FactoryGirl.create(:assignment, :role => FactoryGirl.create(:admin_role), :user => user )
    end
  end

  factory :role do
    description { "Clerical-#{rand(99)}" }

    factory :admin_role do
      description "Admin"
    end
  end

  factory :assignment do
    user
    role
  end

  # Patients Module

  factory :patient_bill_heading do


      sequence(:bill_heading) { |n| "bill-heading-#{n}" }
      sequence(:abbreviation) { |n| "abbreviation-#{n}" }


      factory :delete_patient_bill_heading, :class => PatientBillHeading do
        bill_heading :bill_heading
        abbreviation :abbreviation
      end

  end  
end

这是我认为调用生成嵌套属性字段的帮助程序的链接。

<p>
  <%= link_to_add_fields "Extended Bill Heading", f, :patient_extended_bill_headings %>
</p>

这里是帮手。

helpers/application_helper.rb

  def link_to_add_fields(name, f, association, options={})
    defaults = {
      :partial_name => nil
    }
    options = defaults.merge(options)

    new_object = f.object.send(association).klass.new
    id = new_object.object_id
    fields = f.fields_for(association, new_object, child_index: id) do |builder|
      if options[:partial_name].nil?
        render(association.to_s.singularize + "_fields", f: builder)
      else
        render(options[:partial_name], f: builder)
      end
    end
    link_to("#{name} <i class='icon-plus icon-white'></i>".html_safe, 
            '#', 
            class: "btn btn-success add_fields",
            data: {id: id, fields: fields.gsub("\n", "")}
           )
  end

我正在努力提高我的 RSpec 测试知识，因为我在一个小时试图弄清楚为什么我的测试失败后已经成功地在我的应用程序中构建了这个工作。所以在应用程序中它可以工作，但我想了解如何让我的测试通过。

我是否断言一个错误是由于使用 js 创建链接，而 capybara 没有运行它，因为我不使用 :js => true 选项？

使用 :js => true 选项时，谁能看到我做错了什么？

您可能config.use_transactional_fixtures = true在您的 spec_helper.rb 中有。它不适用于 Capybara javascript 规范，因为服务器和浏览器客户端在不同的线程上运行。由于服务器上的数据库事务对客户端不可见，客户端不知道您在 let!() 中创建的用户，因此用户无法登录系统。

您需要在每次运行之前/之后为您的 js 规范关闭事务装置并清理数据库（考虑 gem database_cleaner ）。

RSpec.configure do |config|
  config.use_transactional_fixtures = false

  config.before(:suite) do
    DatabaseCleaner.clean_with :truncation
  end

  config.before(:each) do
    if example.metadata[:js]
      DatabaseCleaner.strategy = :truncation
    else
      DatabaseCleaner.strategy = :transaction
    end
    DatabaseCleaner.start
  end

  config.after(:each) do
    DatabaseCleaner.clean
  end
end
