before and after do not work (not another DSL in before/after post)

So I am well aware we can’t do DSL things in the before/after, but it looks like they do not even fire. From the below code in Gatling 3.0 I do not get the println statements and I do not reach the breakpoints in intellij. I have to be missing something pretty obvious here.

My Simulation:


import io.gatling.core.Predef._
import io.gatling.http.Predef._

class Sample extends Simulation {

 val httpProtocol = http

 val headers_0 = Map(
  "accept" -> "text/html,application/xhtml+xml,application/xml;q=0.9,image/webp,image/apng,*/*;q=0.8",
  "accept-encoding" -> "gzip, deflate, br",
  "accept-language" -> "en-US,en;q=0.9",
  "cache-control" -> "max-age=0",
  "upgrade-insecure-requests" -> "1",
  "user-agent" -> "Mozilla/5.0 (Macintosh; Intel Mac OS X 10_14_3) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/72.0.3626.121 Safari/537.36")

 def before = {
  println("In the Before")

 def after = {
  println("All done!")

 val scn = scenario("Sample")



In case it matters I am running the simulation via a object. See below:


import io.gatling.core.config.GatlingPropertiesBuilder

object temp {

  def main(args: Array[String]): Unit = {
    val simulation = classOf[Sample].getName
    val runner = new GatlingPropertiesBuilder





Incorrect syntax, you’re just creating your own methods that we of course don’t call.

yep, that would be the something obvious. Thank you for the help.
