Question

我使用gatling插件进行了性能测试。如果在负载配置文件中使用constantUsersPerSec，则模拟将起作用。如果将其更改为atOnceUsers，则模拟不会运行。没有负载

我尝试了其他注入类型，例如rampUsers，这也可行。看来atOnceUsers是唯一失败的场景

setUp(
    login.inject(        
     constantUsersPerSec(1) during (10 seconds))
      .protocols(protocol)
  )

此设置有效并且测试运行。如果我将设置更改为

setUp(
login.inject(
atOnceUsers(1))
.protocols(protocol)
)

然后不运行负载。由于未生成负载，因此未生成报告。

这是运行日志输出是

我刚刚尝试在karate-gatling-demo中使用atOnceUsers(10)，并且有效。

也许加特灵要求数字大于1？
