Ruby 1.9.3,RSpec 2.13.0,WebMock 1.17.4,Rails 3
我正在为公司应用编写测试。有问题的控制器显示客户拨打电话的表格,并允许排序/过滤选项。
编辑测试失败,因为使用我当前的设置,路径无法呈现,因为recorder_server
未在本地运行,或者未正确设置。请帮助。
A Errno::ECONNREFUSED occurred in recordings#index:
Connection refused - connect(2)
/usr/local/lib/ruby/1.9.1/net/http.rb:763:in `initialize'
-------------------------------
Request:
-------------------------------
* URL : http://www.recorder.example.com:8080/recorded_calls
* IP address: 127.0.0.1
* Parameters: {"controller"=>"recordings", "action"=>"index"}
* Rails root: /var/www/rails/<repository>
到目前为止,这是我的规格。
require 'spec_helper'
include Helpers
feature 'Exercise recordings controller' do
include_context "shared admin context"
background do
canned_xml = File.open("spec/support/assets/canned_response.xml").read
stub_request(:post, "http://recorder.example.com:8080/recorder/index").
with(body: {"durations"=>["1"], "durations_greater_less"=>["gt"], "filter_from_day"=>"29", "filter_from_hour"=>"0", "filter_from_minute"=>"0", "filter_from_month"=>"12", "filter_from_year"=>"2014", "filter_prefix"=>true, "filter_to_day"=>"29", "filter_to_hour"=>"23", "filter_to_minute"=>"59", "filter_to_month"=>"12", "filter_to_year"=>"2014"}, # "shared_session_id"=>"19f9a08807cc70c1bf41885956695bde"},
headers: {'Accept'=>'*/*', 'Content-Type'=>'application/x-www-form-urlencoded', 'User-Agent'=>'Ruby'}).
to_return(status: 200, body: canned_xml, headers: {})
uri = URI.parse("http://recorder.example.com:8080/recorder/index")
visit recorded_calls_path
end
scenario 'show index page with 1 xml result' do
#page.save_and_open_page
expect(title).to eq("Recorded Calls")
end
end
这是RecordingsController
class RecordingsController < ApplicationController
# before_filter options
def index
test_session_id = request.session_options[:id]
#Make request to recording app for xml of files
uri = URI.parse("http://#{Rails.application.config.recorder_server}:#{Rails.application.config.recorder_server_port}/recorder/index")
http = Net::HTTP.new(uri.host, uri.port)
xml_request = Net::HTTP::Post.new(uri.request_uri)
xml_request_data = Hash.new
# sorting params
xml_request_data[:shared_session_id] = request.session_options[:id]
xml_request.set_form_data(xml_request_data)
response = http.request(xml_request)
if response.class == Net::HTTPOK
@recordings_xml = XmlSimple.xml_in(response.body)
@recordings_sorted = @recordings_xml["Recording"].sort { |a,b| Time.parse("#{a["date"]} #{a["time"]}") <=> Time.parse("#{b["date"]} #{b["time"]}") } unless @recordings_xml["Recording"].nil?
else @recordings_xml = Hash.new
end
end
# other defs
end
非常感谢任何和所有建议。谢谢。

我在B-Seven的帮助下回答了我自己的问题以及一系列评论。逐个文件,我将列出为正确使用WebMock所做的更改。
Gemfile
下的group :test, :development
。
bundle install
解决依赖关系设置spec_helper.rb
以禁用“Real HTTP连接”。 (这是在这个令人费解的过程中稍后收到的回溯错误。)根据我的理解,这允许将所有“真实连接”转换为localhost
连接并脱机工作......从理想情况来说,这是非常好的不希望外部应用程序的服务器同时运行。
require 'webmock/rspec'
WebMock.disable_net_connect!(allow_localhost: true)
在我的test.rb
环境文件中,recorder_server
和port
的配置已被注释掉...如果未注释,控制器将引发一个说明未初始化常量的异常。我使用测试服务器/端口(用example
的公司名称替换)作为规范存根的布局。
在recordings_controller_spec.rb
中,我已经想出了如何制作一个固定的XML响应。通过上述这些更改,我的规范能够在外部辅助应用程序上正确存根响应,并使用此类响应正确呈现与正在测试的控制器关联的视图。
require 'spec_helper'
include Helpers
feature "Exercise recordings_controller" do
include_context "shared admin context"
# A background is currently not used, because I have 3 scenario types... No xml
# results, 1 result, and 2 results. I will later DRY this out with a background,
# but the heavy lifting is over, for now.
scenario "show index page with 1 xml result" do
canned_xml_1 = File.open("spec/support/assets/canned_response_1.xml").read
stub_request(:post, "http://recorder.example.com:8080/recorder/index").
with(headers: {'Accept'=>'*/*', 'User-Agent'=>'Ruby'}).
to_return(status: 200, body: canned_xml_1, headers: {})
uri = URI.parse("http://recorder.example.com:8080/recorder/index")
visit recorded_calls_path
title.should == "Recorded Calls"
page.should have_content("Search Results")
page.should have_content("Inbound", "5551230000", "175", "December 24 2014", "12:36:24", "134")
end
end
localhost:3000
。他说这是不对的。经过进一步的研究,我同意,因为与WebMock的存根通常是为外部 http连接保留的。:get
存根请求。一位同事指出,回溯建议使用:post
。这是让我的规格通过的最后一块。test.rb
中取消注释这些配置的原因。答案 1 :(得分:1)
你为什么要捣毁localhost?我想你想
stub_request(:get, "http://#{Rails.application.config.recorder_server}:#{Rails.application.config.recorder_server_port}/recorder/index").
