Hi,

I am getting below error in while running gatling test. Test finishes and fails when report is being generated.

Simulation finished

Please help me with this error.

I’d say your gatling-highcharts jar version is not aligned with your gatling-chars jar one.

I am using below dependencies in Gradle

dependencies {
// Gatling dependencies
compile ‘io.gatling:gatling-app:2.0.0-RC2’
compile “io.gatling.highcharts:gatling-charts-highcharts:2.0.0-RC2”

}

Sorry, I’d didn’t properly read the stacktrace.

You mustn’t have spaces in the path (not sure why, I haven’t investigated yet), so /var/lib/jenkins/jobs/SIC-API Post Load Test/workspace/results/APIPost-1409004716082 is not good.
It’s one of the first warnings in the doc: http://gatling.io/docs/2.0.0-RC2/quickstart.html#installing
and it also holds when running from Jenkins.

Please rename your job.

Stephane,

Thanks for you quick reply :slight_smile:

I renamed the job, but it is giving same error.

The issue seem to occur especially when i use Throttle statement in scenario setup

setUp(scn.inject(rampUsers(5).over(5 seconds)))
.throttle( reachRps(5) in (120 seconds), holdFor(500 seconds))
.protocols(httpConf)

when i use constant Users per sec , i dont see above error. Any reason you can think about?

Could you locate the “createactivity-1409008444056” folder somewhere else on your file System?

For the benefit of others who run into the same issue make sure you have file as a data writer in gatling.conf. I ran into the same issue and spent a good hour trying to figure this out

gatling {
  data {
    writers = "console, file"
