You have problems with WebMock,

Question

Ruby 1.9.3, RSpec 2.13.0, WebMock 1.17.4, Rails 3

I am writing tests for a company application. The controller in question displays a table of calls placed by the client and allows you to select sorting / filtering options.

EDIT The test failed because with my current setup the path is not displayed because recorder_servereither it doesn’t work locally or it’s not configured correctly. Also help with this.

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>

• As the call is placed, its data is attached to an XML file created by an external API called Recorder
• RecordingsController accepts the xml file and parses it for hash.

require 'spec_helper'

  include_context "shared admin context"

    canned_xml = File.open("spec/support/assets/canned_response.xml").read

      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"},

      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

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

localhost? ,

stub_request(:get, "http://#{Rails.application.config.recorder_server}:#{Rails.application.config.recorder_server_port}/recorder/index").
