Dynamic feeders - help!

Gatling (Open-Source)

I have a method that generates data and writes to a csv file in before method

val outputFile = new BufferedWriter(new FileWriter(“src/test/resources/primarycompany.csv”))

val csvWriter = new CSVWriter(outputFile, ‘\n’, CSVWriter.NO_QUOTE_CHARACTER)

before{
createContact()
}

def createContact(): Unit = {
var noOfContacts: Int = 3
listOfRecords += csvSchema
for (i ← 0 until noOfContacts) {
api.data = new JSONObject
api.setContacts()
response = api.createContact(path, 201)
ContactID = response.path(ContactsEnum.mcr_contact_id.keys)
primaryContactIDList.add(ContactID.toString)
}
try{
listOfRecords += GetStringArray(primaryContactIDList)
csvWriter.writeAll(listOfRecords.toList)
}
finally{
csvWriter.close()
}
}

As seen above am writing the values to primarycompany.csv

I wanted to use this file as feeder but "Feeder source is empty" though it has values in it.

Help pls!

Hello,

First, before hook is run after the initialization and “before” the actual simulation (see the lifecycle).

The feeder is initialized before the before hook and then has already check that the source is empty or not.

Solution: you should use the batch loading mode

But, sadly, we had an issue with this loading mode, and we fix in the next release.
You’ll find the fix in Gatling 3.5.0 (release in progress)

Sébastien,
