How can I get a random url for an HTTP request for gatling?

Question

I would like to get a random url for http request for gatling

My script is defined as follows:

import io.gatling.core.Predef._ import io.gatling.http.Predef._ import scala.concurrent.duration._ import scala.util.Random class testSimulation extends Simulation { val httpConf = http.baseURL("OURURL") val scn = scenario("View HomePages") .exec( http("Home page") .get("/" + new Random().nextInt()) .resources( http("genericons.css").get("/wp-content/themes/twentyfifteen/genericons/generi$ http("style.css").get("/wp-content/themes/twentyfifteen/style.css?ver=4.2.3"), http("jquery.js").get("/wp-includes/js/jquery/jquery.js?ver=1.11.2"), http("jquery-migrate.min.js").get("/wp-includes/js/jquery/jquery-migrate.min.j$ http("skip-link-focus-fix.js").get("/wp-content/themes/twentyfifteen/js/skip-l$ http("functions.js").get("/wp-content/themes/twentyfifteen/js/functions.js?ver$ http("wp-emoji-release.min.js").get("/wp-includes/js/wp-emoji-release.min.js?v$ http("wp-emoji-release.min.js").get("/wp-includes/js/wp-emoji-release.min.js?v$ http("skip-link-focus-fix.js").get("/wp-content/themes/twentyfifteen/js/skip-l$ http("functions.js").get("/wp-content/themes/twentyfifteen/js/functions.js?ver$ ) ) setUp( scn.inject ( rampUsersPerSec(1) to(300) during(60 seconds), constantUsersPerSec(300) during(600 seconds) ) .protocols(httpConf) ) } 

I have only one random number generated instead of a single request. Do you know how to solve it? Thanks!

You pass in the value, so of course new Random().nextInt receives the call only once when the simulation is built.

You must pass Expression , that is, a function. Only then will it be evaluated every time.

 .get(session => "/" + new Random().nextInt())
