I am considering moving to Gatling 2.0.0-M3a, but I am having issues getting a basic test working. The issue I am having is mapping values to a template file in Gatling 2. The examples below show how I achieved this in Gatling 1.5, but I can't figure it out in 2.

LoginScenario.scala - works in gatling 1.5

package StressTesting import com.excilys.ebi.gatling.core.Predef._ import com.excilys.ebi.gatling.http.Predef._ import Headers._ import akka.util.duration._ import bootstrap._ object LoginScenario { val scn = scenario("Login") .feed(csv("user_credentials.csv")) .exec( http("login") .post("/api/login") .fileBody("loginTemplate", Map( "userName" -> "${userName}", "password" -> "${password}" ) ).asJSON .headers(post_header) .check(status.is(200))) }

LoginScenario.scala - ERRORS - Reworked version to accommodate changes between Gatling 1.5 and 2

package StressTesting import io.gatling.core.Predef._ import io.gatling.http.Predef._ import Headers._ import scala.concurrent.duration._ import bootstrap._ import io.gatling.core.session.Expression object LoginScenario { val scn = scenario("Login") .feed(csv("user_credentials.csv")) .exec( http("login") .post("/api/login") .body(ELFileBody("request-bodies/loginTemplate.ssp", Map("userName" -> "${userName}","password" -> "${password}"))).asJSON .headers(post_header) .check(status.is(200)) ) }

loginTemplate.ssp - Template used in both examples
