测试轨道使用RSpec＆AMP +骨干申请;水豚 [英] testing rails+backbone application with rspec & capybara

问题描述

我正在写一个测试我与上市宝石应用程序。我找不到如何设置水豚与骨干网（阿贾克斯全部）的结果工作
例如测试：

I'm writing a tests for my app with listed gems. I couldn't find how to set Capybara to work with backbone (ajax in all)
example test:

require 'spec_helper' describe "Main" do   describe "GET /" do
    it "displays articles" do
      Article.create!(title:'title',body:'<p>body text</p>')
      visit '/'
      page.should have_content('body text')
    end   
  end 
end

和测试的输出：

Failures:

  1) Main GET / displays articles
     Failure/Error: page.should have_content('body text')
       expected there to be text "body text" in "Loading..."
     # ./spec/features/main_spec.rb:8:in `block (3 levels) in <top (required)>'

正在加载...在我看来模板中的pre阿贾克斯文字...

"Loading..." is the pre ajax text in my view template...

问题的关键是，我不想在此刻用茉莉花为这个应用程序

The point is that I don't want to use Jasmine at the moment for this app

推荐答案

它看起来像您正在使用默认的机架::测试驱动程序，这意味着没有JavaScript的运行水豚。机架::测试加载过程中您的应用程序和假货的水豚API后面的浏览器的DOM。

It looks like you are running Capybara with the default Rack::Test driver, which means no JavaScript. Rack::Test loads your app in process and fakes a browser DOM behind the Capybara API.

您需要使用运行在一个真正的Web浏览器测试的驱动程序。有几个不同的选择：一个司机硒自带的水豚并运行你在一个真正的浏览器（通常Firefox）的测试，其他人都在不同的宝石，如的骚灵，它使用PhantomJS和无头WebKit浏览器。

You need to use a driver that runs your tests in a real Web browser. There are a few different options: a Selenium driver comes with Capybara and runs your tests in a real browser (normally Firefox), others are implemented in separate gems, such as Poltergeist which uses PhantomJS and the headless WebKit browser.

有对水豚说明自述有关设置正确的驱动程序。您可以切换一组测试中加入 JS 选项为一个描述块，例如使用JavaScript支持驱动程序：

There are instructions on the Capybara readme about setting up the right driver. You can switch a group of tests to use a JavaScript supporting driver by adding the js option to a describe block, e.g.:

describe "Main with JavaScript", :js => true do
  # ...
end
