gradlew gatlingRun doesn't run any test

Question

I am trying to perform a load testing with gradle-gattling, below are my build.gradle and my BasicSimulation.scala

plugins {
    id "com.github.lkishalmi.gatling" version "3.0.2"
}
repositories {
    mavenCentral()
}
apply plugin: 'scala'
dependencies {
    testCompile 'junit:junit:4.12'
    compile 'org.scala-lang:scala-library:2.11.8'
}

gatling {
    simulations = {
        include "**/predictors/*.scala"
    }
}

gatlingRun {
    systemProperties 'endpoint': "${endpoint}"
}

I put the BasicSimulation.scala in the src/gatling/predictors folder.

package predictors

import io.gatling.http.Predef._
import io.gatling.core.Predef._
class BasicSimulation extends Simulation {
  val httpConf = http.baseURL("http://localhost:8000/")
  val scn = scenario("Basic Simulation")
    .exec(http("request_1")
      .get("api/chemocare/gatling/"))
    .pause(5)
  setUp(
    scn.inject(atOnceUsers(80))
  ).protocols(httpConf)
}

I set up my rest-api and test it with postman. It works fine. However, when I run gradlew gatlingRun, it seems like none of the test is executed and no report is generated. I got this message instead:

BUILD SUCCESSFUL in 1s
1 actionable task: 1 executed

How do I execute and register the test?

Did you try to put your file into `src/gatling/simulations` with a closure that includes every file with extension `.scala`? — Lukas Körfer, Aug 30 '19 at 11:28
yes, I added my file to several folders, I've also tried to include those folder in my build.gradle. But no luck so far. — Saber Alex, Aug 30 '19 at 11:33
The setup from your current example cannot work, because the `src/gatling/simulations` is the base path and every `include` is evaluated starting from this base path. — Lukas Körfer, Aug 30 '19 at 11:37
Yep, it is now detect the simulation, though I got an error `Caused by: java.lang.RuntimeException: Some simulations failed : BasicSimulation`. I can work from that. Thanks — Saber Alex, Aug 30 '19 at 13:15
The gardle plugin is now officially part of Gatling: https://gatling.io/docs/current/extensions/gradle_plugin. The new default location for simulations is now `src/gatling/scala` and `src/gatling/resources` — Younes El Ouarti, Oct 01 '20 at 11:47

I had the same problem and wanted to share my solution, as it deviates a bit from the comments.

In general it is true, that a BUILD SUCCESSFUL without running a test, might indicate that Gatling wasn't able to find the simulations.

In my case I've been running:

gradle gatlingRun-MySimulation

What I've missed is that xyz in gatlingRun-xyz has to be a fully qualified name. So the command should be

gradle gatlingRun-org.corp.pkge.MySimulation

In local, I tried with below approach working fine for me ->

gradle clean build -> to clean build the project

./gradlew gatlingRun-com.project.sample.performance.simulations.sample.SampleBaseSimulation-> to run the single file

gradle gatlingRun-com.project.sample.performance.simulations.sample.SampleBaseSimulation-> to run the single file

gradle gatlingRun -> to run all simulations

I had the same problem, I was getting BUILD SUCCESSFUL but test was not running.

I gave correct command (below command) to run gatling test, in fact which was working earlier, suddenly stopped working. After a bit of investigation I have got to know that build files have been replaced with old files.

I deleted content in build folder in gatling module and rebuilt the module, then the source files have been build into build folder, then the below command starts working again

./gradlew myproject-service-gatling:gatlingRun-com.org.myproject.StoreMyQueriesToSolrGatlingTest

My project structure

  Root_Proj

   |__ myproject-service
   
          |__ src

               |__ gatling [myproject-service-gatling]
                   
                    |__ build

                         |__ resources

                         |__ scala

               |__ main
          
                    |__ java

                    |__ resources

               |__ test

                    |__ java

                    |__ resources

Somebody may place simulations in the wrong package (by default IntelliJ IDEA creates main/scala or main/java source set when you are creating an empty Gradle project)

Check does your files are placed in gatling/scala package

And then run all simulations using ./gradlew clean gatlingRun command

gradlew gatlingRun doesn't run any test
