Multiple records from same CSV feeder

Gatling (Open-Source)
1

Hey Everyone,

I am using Gatling 3. I have a csv feeder with just one column titled “accountIds”. I need to pass more than one random records from the feeder in the body of my POST request. I do it like this:

val searchFeeder = csv("data/accountids.csv").random

val scn1 = scenario("Scenario 1") // A scenario is a chain of requests and pauses
  .feed(searchFeeder,2)
  .exec(http("Search")
    .post("/v3/accounts/location/search")
    .body(StringBody("""{"accountIds": ["${accountIds}"]}""")).asJson)

setUp(scn1.inject(atOnceUsers(10)).protocols(httpConf))

I get the error:

Failed to build request: No attribute named ‘accountId s’ is defined

This works fine if I remove the 2 from the feed function and use just one argument in .feed(searchFeeder).

Thank you for the help

Failed to build request: No attribute named ‘accountId s’ is defined

It looks like you have copy pasted a non printable character between the ‘d’ and the ‘s’ characters in your Gatling expression.

That might be a typo from my end. I changed the column header of the file to accounts. I still get the same error:

Search: Failed to build request: No attribute named ‘accounts’
is defined

No, that’s not the same error.

Search: Failed to build request: No attribute named ‘accounts’

Yes but I changed the column header of my csv file to ‘accounts’. This is the change:

val scn1 = scenario("Scenario 1")
  .feed(searchFeeder,2)
  .exec(http("Search")
    .post("/v3/accounts/location/search")
    .body(StringBody("""{"accountIds": ["${accounts}"]}""")).asJson)

This works perfectly well if I remove the 2 from the feed function.

Also, I have tried it with feeders other than csv. The error remains.

Thank you for the help.

Should it be “${accounts1}” and “${accounts2}”?https://gatling.io/docs/current/session/feeder
