我正在使用SoapUI Pro 5.1.2对camunda BPM 引擎的 REST API运行负载测试,我得到了大约 10-30% 的失败,但有以下异常。

这是负载测试场景:

  • 在我的测试用例中,我按顺序执行了一系列 REST 调用。
  • 负载测试属性 - 线程:100,Startegy:Burst,Burst Delay:10s,Burst Duration:5s,限制 1000 总运行。

我尝试将 SoapUI 的 'Socket Timeout' 选项设置为 300000 即 300 秒,我发现这是我在论坛上找到的唯一选项,但我仍然收到这些错误。此外,正如我所提到的,并非所有 1000 次运行都是失败的,只有 10-30 % 的运行随机失败,除了这个例外。

有时,负载测试会成功,将总运行次数限制在 500 次以下,即使这样,我也会遇到其中一些错误,并且偶尔会出现。

从上面的跟踪中,我了解到问题出在客户端(SoupUI)方面(或者我的理解不对?)并且想知道如何解决这个问题?

我之前在 SoapUI 的全局设置中设置了套接字超时,但我在SmartBear 论坛中发现我们为测试用例提供了单独的套接字超时选项。当我为测试用例设置超时时它起作用了。

如果您的流程是同步的,则启动流程的 REST 调用将阻塞,直到流程完成。这意味着如果该过程花费的时间比您配置的套接字超时时间长,则连接将被关闭,因为套接字上不需要更多数据。一种解决方案是将流程的开始事件设置为异步,以便 REST 调用将立即返回。但我不知道这是否符合您的基准。
