Question

我想在加特林sbt项目中使用命令行参数传递加速用户，调节持续时间，保持持续时间等。

例如：

val rampUpUserCount  =  Integer.parseInt(System.getProperty("rampUpUsers"))
val rampUpDuration = Integer.getInteger(System.getProperty("rampUpDuration"))

我正在测试中

setUp(
    test.homePageScenario.inject(
      nothingFor(10 seconds),
      rampUsers(rampUpUserCount) over (rampUpDurationInMins minutes)
))

，并在我通过时通过命令行

 sbt gatling:testOnly simulations.test.gateway -DrampUpUsers=200 -DrampUpDuration=20

我得到NumberFormatException

请有人可以帮助我吗？谢谢

您需要将参数移至任务gatling:testOnly

之前

 sbt -DrampUpUsers=200 -DrampUpDuration=20 gatling:testOnly simulations.test.gateway

在加特林sbt项目中传递命令行参数
