custom feeders implementation

Gatling (Open-Source)
1

I am new to use scala and gatling. Wondering if you can give me some suggestions on how to do this:

I am trying to implement my own feeder function, which basically is reading a csv file and then massage the data and return for the httpconfig to use:

e,g, I have the feed file as groups.csv

groupname,grouptype

the custom feeder will return groupname+"/community" if grouptype is community, and return groupname + “/others” when grouptype is group. There is a sample code here: https://github.com/excilys/gatling/wiki/Feeders

But that one randomly create the data. For me, I need to get each record from the csv file first and then manupulate the data accordingly and then feed it back to the httpConfig.

Thx advance for the help!

csv(“groups.csv”).map{
case header @ List(“groupname”, “grouptype”) => header

case List(groupname, “community”) => List(groupname + “/community”)
case List(groupname, _) => List(groupname + “/others”)
case r => throw new IllegalArgumentException("Unexpected record " + r)
}

csv produces an Array[Map[String, String]], so you just have to map it.

If you want to learn some Scala basics, I advice you have a look at the Twitter’s Scala School first chapters: http://twitter.github.io/scala_school/
