Question

我正在使用 SoapUI Pro 5.1.2 对 camunda BPM引擎的REST API 进行负载测试，并且我得到了大约10-30％的失败，并出现以下异常

这是负载测试场景：

在我的测试用例中，我按顺序完成了一系列REST调用。

加载测试属性 - 线程：100，Startegy：Burst，Burst Delay：10s，Burst Duration：5s，Limit 1000 Total Runs。

我已经尝试将SoapUI的“套接字超时”选项设置为300000，即300秒，我看到这是我在论坛上找到的唯一选项，但我仍然遇到这些错误。另外，正如我所提到的，并非所有1000次运行都是失败的，只有10-30％的运行失败，并且出现此异常。

有时，负载测试会成功将总运行时间限制在500以下，即使这样，我也会遇到一些错误并偶尔发生。

从上面的描述，我理解问题是在客户端（SoupUI）方面（或者我的理解不对吗？）并且想知道如何解决这个问题？

Answer 1

如果您的进程是同步的，则启动该进程的REST调用将阻塞，直到该进程完成。这意味着如果进程花费的时间超过配置的套接字超时，则连接将被关闭，因为套接字上不再需要其他数据。解决方案是将进程的启动事件设置为async，以便REST调用立即返回。但我不知道这是否符合您的基准。

Answer 2

我之前在SoapUI的全局设置中设置了套接字超时，但我在SmartBear forum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，它就可以工作。
