ruby-on-rails-3 - VCR仅运行一次，就可以在带有 Selenium Webkit的 capybara 中进行集成测试

我将Rspec与Capybara一起使用，使用VCR gem运行集成测试来模拟api请求的存根。
我面临着一个奇怪的问题。该测试首次成功运行，并创建了yaml文件来保存请求及其响应。
但是，如果在创建yaml文件后再次运行测试，则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

而我的整合测试：-

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="[email protected]"
        #and other code
      end
    end
  end
end

最佳答案

实际上，它正在考虑将所有“访问”的本地主机请求作为api调用。
因此，只需忽略“ localhost”请求即可修复它们。
简单地将以下内容写在vcr.rb文件中

c.ignore_localhost = true
