如何在JMeter中测试异步回调? [英] How can I test async callbacks in JMeter?

问题描述

我在我的API中使用WebHooks.因此，一旦处理了请求，我们的REST服务就会将响应回发到请求中发送的回调URL.

I am using WebHooks in my API. So, once a request is processed our REST Service will POST a response back to the callback URL sent in the request.

Client             Server
  |(request)         |
  |----------------->|     
  |<-----------------|     ||
  |        (response)|     ||
  |                  |    _||_ Time
  |        (callback)|    \  /
  |<-----------------|     \/
  |----------------->|
  |(response)        |
  |                  |

推荐答案

如果要轮询，则取决于WebHook的实现-您可以只使用交易控制器

It depends on WebHook implementation, if it is a matter of polling - you can just use While Controller to wait for callback in loops. The whole duration of the sequence can be measured using i.e. Transaction Controller

如果回调来自服务器发送的事件，则可以使用 JAX RS API ，它提供了 JSR223采样器或

If the callback comes a a Server-Sent Event you can use i.e. JAX RS API which provides SseEventSource class which can be used for waiting for server-side events either in JSR223 Sampler or in Java Request sampler like described in Stress/Load-Testing of Asynchronous HTTP/REST Services with JMeter article
