VCR仅使用selenium webkit在capybara中进行一次集成测试

Question

我正在使用Rspec与Capybara运行使用VCR gem的集成测试来模拟存根api请求.我面临着各种奇怪的问题.测试第一次成功运行并创建yaml文件以保存请求及其响应.但是如果我在创建yaml文件后再次运行测试,那么它会遇到问题并显示以下问题: -

     VCR::Errors::UnhandledHTTPRequestError:


       ================================================================================
       An HTTP request has been made that VCR does not know how to handle:
         GET http://127.0.0.1:58021/__identify__

       VCR is currently using the following cassette:
         - /home/pcname/appname/selenium-error/fildername/appaname/cassettes/acceptanceTest/AffiliateSignUpProcess.yml
         - :record => :once
         - :match_requests_on => [:method, :uri]

       Under the current configuration VCR can not find a suitable HTTP interaction
       to replay and is prevented from recording new requests. There are a few ways
       you can deal with this:

         * If you're surprised VCR is raising this error
           and want insight about how VCR attempted to handle the request,
           you can use the debug_logger configuration option to log more details [1].
         * You can use the :new_episodes record mode to allow VCR to
           record this new request to the existing cassette [2].
         * If you want VCR to ignore this request (and others like it), you can
           set an `ignore_request` callback [3].
         * The current record mode (:once) does not allow new requests to be recorded
           to a previously recorded cassette. You can delete the cassette file and re-run
           your tests to allow the cassette to be recorded with this request [4].
         * The cassette contains 64 HTTP interactions that have not been
           played back. If your request is non-deterministic, you may need to
           change your :match_requests_on cassette option to be more lenient
           or use a custom request matcher to allow it to match [5].

以下是我的vcr.rb: -

VCR.configure do |c|
  c.allow_http_connections_when_no_cassette = true
  c.hook_into :fakeweb
  c.cassette_library_dir     = 'cassettes'
end

我的集成测试: -

需要'spec_helper'

describe "AffiliateSignUpProcesses", :js => true  do
  describe "Sign up using affiliate link" do
    it "should create User/Affiliate/AffiliateToken and Conversion when user is created" do
      VCR.use_cassette("acceptanceTest/AffiliateSignUpProcess", :record => :once) do
        visit pricing_path(:aid => 'this_is_sample_value')
        @email="static_for_vcr@testdomain.com"
        #and other code
      end
    end
  end
end

实际上它正在考虑所有localhost请求"访问"作为api调用.所以只需要通过忽略"localhost"请求来修复它们.Simpley在vcr.rb文件中写下以下内容

c.ignore_localhost = true
