单元测试 – 一个测试用例似乎干扰了其他测试用例

这是在Rails 4.0.11上.我正在使用minitest和webmock为与API交互的工作者编写测试.我的测试文件中有两个测试用例(到目前为止).当我运行两个测试时,第二个(标题中“成功”的那个)失败.当我注释掉通过测试(标题中“重试”的那个)时,失败的测试用例通过了.似乎测试用例互相干扰,但我不知道如何.

(我在这些代码示例中对公司的机密数据进行了模糊处理.嗨老板！)

这是测试：

require 'test_helper'

  REQUEST_HEADERS = {'Accept'=>'*/*','Accept-Encoding'=>'gzip;q=1.0,deflate;q=0.6,identity;q=0.3','Content-Type'=>'text/xml','User-Agent'=>'Ruby'}

  test "retry codes leave activity processor step in waiting state and activity in auto_processing state" do

这是工人：

class FoocorpVipCheckStatusWorker
  @queue = :short_running

  # Foocorp VIP returns an order-level status code and description
  # and a line-level status code and description. The comments describing
  # the status codes in STATUS_CODE_MATRIX are from Foocorp's Docs.
  #
  # Array format for status codes is:
  # ["(order-level status code)","(line-level status code)"]

  STATUS_CODE_MATRIX = {
    :success  => [
      ["00057","00051"]  # Request Processed Successfully
    ],:retry    => [
      ["00057","00053"],# No Status Yet
      ["00057","00054"],# Order processed successfully but activation is pending.
      ["00099",""],# Unexpected error occurred during processing e.g. null pointer exception which causes thread to terminate.
      ["00059",# Server time out occurred.

    ]
  }

  def perform

    ActivityProcessorStep.where(state: "waiting").where("vip_ref_num IS NOT NULL").each do |activity_processor_step|

      client = Remote::Clients::FoocorpVipClient.new(

          :ecpd_id     => activity_processor_step.activity.carrier_account.parent_account.api_access_id,:vip_ref_num => activity_processor_step.vip_ref_num
        }
      )
      response = client.check_status
      #TODO: Remove debugging code
      #binding.pry
      order_status_code = response.first[:order_status_code]
      order_status_desc = response.first[:order_status_desc]
      line_status_code  = response.last[:line_status_code]

      response_message  ||= "No status description given"

      success             = STATUS_CODE_MATRIX[:success].detect{ |codes_array| codes_array == [order_status_code,line_status_code]}.present?
      retry_status_check  = STATUS_CODE_MATRIX[:retry].detect{ |codes_array| codes_array == [order_status_code,line_status_code]}.present?
      stale_request       = retry_status_check && Time.now > (activity_processor_step.created_at + activity_processor_step.days_to_expire.days)

      if success
        activity_processor_step.update_activity_status('Complete',nil,response_message)
      elsif stale_request
        activity_processor_step.update_activity_status('Failure',"Activity processor step expired.")
      elsif !retry_status_check
        activity_processor_step.update_activity_status('Failure',response_message)
      end

    end
  end
end

这是我的终端输出：

运行两个测试用例：

当我同时运行两个测试并在worker中使用binding.pry(这里注释掉)来检查“成功”测试用例(失败的那个)期间的响应值时,我得到以下两个结果.在这两种情况下,我都期望得到相同的结果(第二个).

运行两个测试用例：

[1] pry(#<VerizonVipCheckStatusWorker>)> response
=> [{:order_status_code=>"00057",:order_status_desc=>"",:_summary=>{:order_status_code=>"00057",:order_status_desc=>""}},{:line_status_code=>"00053",:line_status_desc=>"No Status Yet.",:_summary=>{}}]

评论第一个(“重试”)测试用例：

[2] pry(#<VerizonVipCheckStatusWorker>)> response
=> [{:order_status_code=>"00057",{:line_status_code=>"00051",:_summary=>{}}]

最后一个例子中的响应值是我在“重试”测试用例的第一次迭代期间所期望的,而不是在“成功”情况下.

我已经尝试将设置方法中的内容移动到您在此处看到的常量和sample_response_body方法中.我也试过添加这个拆解方法,但它没有帮助：

def teardown
  WebMock.reset!
end

我正在从头开始编写工作者和测试,所以我完全有可能在某处出现愚蠢的语法/逻辑错误.我为可能是一个过于冗长的问题而道歉,但这确实让我撕裂了我的头发.非常感谢您的帮助.谢谢.
