How to run Gatling from source

Gatling (Open-Source)
1

Hey there!)

I have some experience with the contribution to Gatling and during this I used simple tests to check new functionality, etc. But, currenlty I would like to run a scenario. A long time ago, if I clearly remember, I launched some scenarios, but unfortunately I forgot how.

Can you provide steps or instructions for that?

Thank you!

It’s not possible to run Gatling from sources. You have to compile the sources and publish them locally.

Thanks for the answer!

I tried what you wrote but seems like I’m missing something. Can you please help me with the right direction. Here are my steps:

  1. Run sbt "clean;compile;test:compile;publishLocal"
  2. Get archive of the bundle by path $HOME/.ivy2/local/io.gatling/gatling-bundle/3.7.5-SNAPSHOT/zips/gatling-bundle-bundle.zip
  3. Unarchive

Then I saw there isn’t a folder with all dependencies .jar. Is there any way to compile and package all dependencies to the lib folder? Or do I need to create a script which will move all these?

If you want the complete bundle, you’ll have to publishLocal the gatling-highcharts project as well.

Note that you need to ensure they are at the very same version (as gatling-highcharts depends on gatling as same version).

Okey, got it. Thank you!

I found solution. I created:

1) gatling-app/src/test/scala/Engine.scala:

import io.gatling.app.Gatling
import io.gatling.core.config.GatlingPropertiesBuilder

object Engine extends App {

	val props = new GatlingPropertiesBuilder()
		.resourcesDirectory(IDEPathHelper.mavenResourcesDirectory.toString)
		.resultsDirectory(IDEPathHelper.resultsDirectory.toString)
		.binariesDirectory(IDEPathHelper.mavenBinariesDirectory.toString)

	Gatling.fromMap(props.build)
}

2) gatling-app/src/test/scala/IDEPathHelper.scala:

import java.nio.file.Paths

object IDEPathHelper {

	private val projectRootDir = Paths.get(getClass.getClassLoader.getResource("gatling.conf").toURI).getParent.getParent.getParent
	private val mavenTargetDirectory = projectRootDir.resolve("target")
	private val mavenSrcTestDirectory = projectRootDir.resolve("src").resolve("test")

	val mavenSourcesDirectory = mavenSrcTestDirectory.resolve("scala")
	val mavenResourcesDirectory = mavenSrcTestDirectory.resolve("resources")
	val mavenBinariesDirectory = mavenTargetDirectory.resolve("test-classes")
	val resultsDirectory = mavenTargetDirectory.resolve("gatling")
	val recorderConfigFile = mavenResourcesDirectory.resolve("recorder.conf")
}

3) gatling-app/src/test/scala/ExampleSimulation.scala (just example)
4) Set gatling.core.simulationClass = "ExampleSimulation" in gatling.conf
5) Add logback-test.xml
6) Run Engine.scala

Anyway, @slandelle @sbrevet thank you guys)
