  • Http 接口测试框架 (思路 + 实现中 + 开源 + 可能难产)
  • Http 接口测试框架疑问解答
  • Fiddler 保存会话 (请求)

说明

由于部分内容涉及公司机密，已用字母替换，不影响阅读

实际效果

  • 验证1000个接口平均耗时6s（看机器配置及网速）
  • 第一次投入使用，马上发现5个接口异常并且该验证过程不到30s的时间

框架的下一步

  • 目前已兼容我们公司所有app

  • response body全字段验证（含字段类型）

    • 已有思路

  • 字段变化导致2个大问题

    • 由原本int（0/1）变成了布尔型
    • 时间戳长度由10位突然变成13位

  • 尽量避免日常监控中跑接口对外网数据/用户的影响

    • 目前做法是屏蔽相关接口
    • 目前状态
    • 跑接口时创建的数据id有变化，然而删除接口还是调用老的id去删除，导致数据删除不到
    • 改进
    • 拦截创建数据的response body取出对于id
    • 拦截删除接口request body，传入上一步拦截的id

fiddler js 自定义信息


//自定义参数设置
public static var filterUrl = "a-webapi.test.b.com";
public static var filePath = "D:\\Fiddler Sessions\\Api\\";
public static var filePathForRequested = "D:\\Fiddler Sessions\\Requested.txt";
public static var filePathForErrorResponse = "D:\\Fiddler Sessions\\ErrorResponse.txt";
public static var filePathForVerifyRequset = "D:\\Fiddler Sessions\\VerifyRequset.txt";
public static var filePathForRemoveSession = "D:\\Fiddler Sessions\\RemoveSession.txt";
