Ensure CSV records in Gatling using feeder

问题

I have created a simple feeder in Gatling with CSV. The script is working well and not getting any errors. I know values are fetching from the CSV during the load test. But how can I ensure which value is getting for each user. I have to ensure that first user should login with UserName: user1 and Password: password1. As I am very very new to Gatling I could not find a solution for this. Hence please help me to get a solution , Thanks in advance......

My CSV contains-

Username Password

user1 password1

user2 password2

user3 password3

And my gatling script for the feeder is:

val userCredentails= csv("user_credentials.csv").random 
val scn = scenario("RecordedSimulation")
    .exec(http("request_0")
        .get("/thulasi/myhome.php")
        .headers(headers_0)
        .resources(http("request_1")
        .post(uri1 + "/scripts/index.php")
        .headers(headers_1)
        .formParam("Action", "Offline"),
        http("request_2")
        .get(uri1 + "/images/footer.jpg"),

    .pause(75)
    // Login
      .feed(userCredentails)
    .exec(http("request_3")
        .post("/thulasi/index.php")
        .headers(headers_0)
        .formParam("cand_user_cd", "${Username}")
        .formParam("passwd", "${Password}")
        .resources(http("request_4")
        .post(uri1 + "/scripts/index.php")
        .headers(headers_1)
        .formParam("Action", "Offline"))
        )


setUp(scn.inject(atOnceUsers(3))).protocols(httpProtocol)

}

Check Feeder docs: http://gatling.io/docs/2.2.0/session/feeder.html?highlight=feeders

just don't use random on feeder:

val userCredentails= csv("user_credentials.csv")

this will go from first record to last, and crash when there is no more records in CSV = so you have to be sure your tests won't load more records then you have

or use circular:

val userCredentails= csv("user_credentials.csv").circular

this will go from first to last record, over and over again.
