Locust：意外的关键字参数 'user_count'

Question

我有一个 locust 测试成功终止，满足了我指定的所有 environment.stats。然而，某些原因导致 locust 以 code 2 结尾。

这是最终输出。

注意：kill pid 是一个单独的进程，它只是获取 Windows Perf Counter 数据，与 locust.

无关

进一步调查，发现在长日志输出的最顶部有一个未处理的异常。

Answer 1

已修复。

我插入了一个 @events.spawning_complete.add_listener 定义错误的侦听器（没有参数）。

我删除了它，问题就消失了。
