从 Webrat 迁移到 Capybara...不成功

希望有人可能会看到我忽略的内容...

我正在尝试让水豚在现有的小型应用程序中工作...但我没有任何运气。

Gemfile：

  group :development, :test do
    gem 'rspec-rails'
    # gem 'webrat'
    gem 'capybara', :git => 'git://github.com/jnicklas/capybara.git'
  end
  ...

两个地方的类似规范由于不同的原因而失败。不知道为什么？

spec/controllers/pages_controller_spec.rb：

require 'spec_helper'

describe PagesController do

  describe "GET 'about'" do
    it "should be successful" do
      # get 'about'                         #worked w/ webrat
      # response.should be_success          #worked w/ webrat
      visit pages_about_path
      # page.should have_content('About Us') 
      page.html.should match(/About/i)
    end

    it "should have title" do
      # get 'about'                         #webrat
      # response.should have_selector("title", :content => "About Us") #webrat
      visit pages_about_path                
      page.should have_selector("title")    
    end
  end  
end

失败： （可能会拉入一些通用页面，因为浏览器中的文档类型是 ""）

  1) PagesController GET 'about' should be successful
     Failure/Error: page.html.should match(/About/i)
       expected "<!DOCTYPE html PUBLIC \"-//W3C//DTD HTML 4.0 Transitional//EN\" \"http://www.w3.org/TR/REC-html40/loose.dtd\">\n\n" to match /About/i
     # ./spec/controllers/pages_controller_spec.rb:13:in `block (3 levels) in <top (required)>'

  2) PagesController GET 'about' should have the right title
     Failure/Error: page.should have_selector("title") 
       expected css "title" to return something
     # ./spec/controllers/pages_controller_spec.rb:20:in `block (3 levels) in <top (required)>'

spec/views/pages/about.html.haml_spec .rb：

require 'spec_helper'

describe "pages/about.html.haml" do
  it "renders attributes in <p>" do
    # render #webrat
    # rendered.should match(/About/) #webrat
    visit pages_about_path
    page.should have_content("About Us")
  end

  it "should have the right heading" do  
    # render #webrat
    # rendered.should have_selector("h2", :content => "About Us") #webrat
    visit pages_about_path
    page.should have_selector("h2")
  end
end

失败：

  1) pages/about.html.haml renders attributes in <p>
     Failure/Error: visit pages_about_path
     NoMethodError:
       undefined method `visit' for #<RSpec::Core::ExampleGroup::Nested_1:0x00000101dc2970>

Hoping someone might see what I've overlooked...

I'm trying to get Capybara working in a small existing application...and I'm not having any luck.

Gemfile:

  group :development, :test do
    gem 'rspec-rails'
    # gem 'webrat'
    gem 'capybara', :git => 'git://github.com/jnicklas/capybara.git'
  end
  ...

Similar specs in two places are failing for different reasons. Not sure why?

spec/controllers/pages_controller_spec.rb:

require 'spec_helper'

describe PagesController do

  describe "GET 'about'" do
    it "should be successful" do
      # get 'about'                         #worked w/ webrat
      # response.should be_success          #worked w/ webrat
      visit pages_about_path
      # page.should have_content('About Us') 
      page.html.should match(/About/i)
    end

    it "should have title" do
      # get 'about'                         #webrat
      # response.should have_selector("title", :content => "About Us") #webrat
      visit pages_about_path                
      page.should have_selector("title")    
    end
  end  
end

Failures:
(may be pulling in some generic page as doctype in browser is "<!DOCTYPE html>")

  1) PagesController GET 'about' should be successful
     Failure/Error: page.html.should match(/About/i)
       expected "<!DOCTYPE html PUBLIC \"-//W3C//DTD HTML 4.0 Transitional//EN\" \"http://www.w3.org/TR/REC-html40/loose.dtd\">\n\n" to match /About/i

       expected css "title" to return something
     # ./spec/controllers/pages_controller_spec.rb:20:in `block (3 levels) in <top (required)>'

spec/views/pages/about.html.haml_spec.rb:

require 'spec_helper'

describe "pages/about.html.haml" do
  it "renders attributes in <p>" do
    # render #webrat
    # rendered.should match(/About/) #webrat
    visit pages_about_path
    page.should have_content("About Us")
  end

刚刚遇到了同样的问题，发现水豚需要：

response.body.should have_selector("title")

webrat 也不需要 .body

，请确保您正在渲染视图，例如：。

describe PagesController do
  render_views

Just had the same issue and found that capybara needs:

response.body.should have_selector("title")

webrat does not need the .body

also, make sure you are rendering views eg:.

describe PagesController do
  render_views

您应该在测试文件中包含 capybara DSL ：

require 'spec_helper'

    describe PagesController do

    include Capybara::DSL

      describe "GET 'about'" do
        it "should be successful" do 
      ...

You should include capybara DSL in your test file :

require 'spec_helper'

    describe PagesController do

    include Capybara::DSL

      describe "GET 'about'" do
        it "should be successful" do 
      ...

这不会解决您的所有问题，但可以改为：

page.html.should match(/About/i)

尝试：（

page.should match(/About/i)

您甚至可能不需要页面）。

另外，检查您是否已将 Capybara 设置为在 env.rb 中使用 CSS 查询（默认为 XPath）。

This won't fix all your problems, but Instead of:

page.html.should match(/About/i)

try:

page.should match(/About/i)

(you might not even need page).

Also, check that you have Capybara set to use CSS queries in env.rb (it defaults to XPath).

确保您的 spec_helper.rb 文件顶部有以下内容：

ENV["RAILS_ENV"] ||= 'test'
require File.expand_path("../../config/environment", __FILE__)
require 'rspec/rails'
require 'rspec/autorun'
require 'capybara/rspec'

我遇到了与您类似的问题（即，未定义的方法“visit”）并弹出这些行解决了问题。

Ensure that your spec_helper.rb file has the following at the top:

ENV["RAILS_ENV"] ||= 'test'
require File.expand_path("../../config/environment", __FILE__)
require 'rspec/rails'
require 'rspec/autorun'
require 'capybara/rspec'

I had a similar issue as yours (i.e., undefined method 'visit') and popping those lines solved the issue.
