Hello Remi,

Lowering the root level to DEBUG will only print the HTTP requests and responses, not the Session content.  
Maybe we should add some DEBUG and TRACE logs to help debugging.

Until then, you can debug your Simulation with a Session function:  
[https://github.com/excilys/gatling/wiki/Session#wiki-functions](https://github.com/excilys/gatling/wiki/Session#wiki-functions)

Regarding your wanting to select a random entry among a check result, you have to:

1. ensure you capture ALL the results of your regex, not only the first one (which is the default): use findAll: [https://github.com/excilys/gatling/wiki/Checks#wiki-extracting](https://github.com/excilys/gatling/wiki/Checks#wiki-extracting)
2. use a transform step in your check in order to save only one of the results: [https://github.com/excilys/gatling/wiki/Checks#wiki-transforming](https://github.com/excilys/gatling/wiki/Checks#wiki-transforming)  
So, you’ll have something like this:

val randomData = new org.apache.commons.math3.random.RandomDataImpl

val selectRandomElementInList = (list: List[String]) =\> {  
val randomIndex = randomData.nextInt(0, list.size - 1)  
list(randomIndex)  
}

…  
…  
check(regex(“XXXXXX”).findAll.transform(selectRandomElementInList).saveAs(“idnr”))

And voila, you can use ${idnr}.

Cheers,

Stéphane

Hello Stephane,

thanks for your reply.  
unfortunately i am getting an error:

Collecting simulations…  
Exception in thread “main” java.lang.RuntimeException: Compilation failed:  
C:\projecten\tools\gatlin\gatling-charts-highcharts-1.2.5\user-files\simulations\Simulation1.scala:54: error: type mismatch;

required: Seq[String] =\> ?  
.check(regex("""\<a href="/video/([^"]\*)""").findAll.transform(selectRandomElementInList).saveAs(“idnr”))  
^  
one error found

do you know what’s going wrong?

My fault.  
As the compiler states, findAll returns a Seq[String], not a List[String].  
You just have to change the selectRandomElementInList signature:

val selectRandomElementInList = (list: Seq[String]) =\> {

val randomIndex = randomData.nextInt(0, list.size - 1)

list(randomIndex)

}

Cheers,

Steph

Thanks & Regards,
