performance-testing - 将 Taurus 与 Gatling 一起使用失败，并出现“线程“主”io.gatling.core.session.el.E​​lParserException 中的异常”

问题描述

我正在尝试用 Taurus 运行 Gatling 来试验它，但它并不像预期的那样容易。

我有这个代码：

 execution:
   - executor: gatling
   scenario: sample

 scenarios:
   sample:
     script: tests/gatling/BasicSimulation.scala
     simulation: tests.gatling.BasicSimulation

并使用这个加特林模拟 scala 代码：

    package tests.gatling
    import io.gatling.core.Predef._
    import io.gatling.http.Predef._
    import scala.concurrent.duration._
    class BasicSimulation extends Simulation {
      val httpConf = http
        .baseURL("http://computer-database.gatling.io")
.acceptHeader("text/html,application/xhtml+xml,application/xml;q=0.9,*/*;q=0.8")
        .doNotTrackHeader("1")
        .acceptLanguageHeader("en-US,en;q=0.5")
        .acceptEncodingHeader("gzip, deflate")
        .userAgentHeader("Mozilla/5.0 (Windows NT 5.1; rv:31.0) Gecko/20100101 Firefox/31.0")
      val scn = scenario("BasicSimulation")
        .exec(http("request_1")
        .get("/"))
        .pause(1)
      setUp(
        scn.inject(atOnceUsers(1))
      ).protocols(httpConf)
    }

当我运行它时：

bzt 加特林.yml

它以错误结尾：

解决方案

不久前我遇到了同样的问题，根本原因是我使用的是 jdk 9 ，我降级到 8 并且它有效。

我试过你的代码，它在 jdk 8 上对我有用
