Hi there,
at first congratulation for publishing RC2 and gatling.io, they are really great.
Now my question. In the documentation, all simulations have the form setup(scenario.inject(…)).protocols().
However, the system we want to test, accesses different REST-Apis with different URLs in parallel. Is there a way to model this behavior with Gatling, i.e. to “bind” a protocol to a scenario ?
Thanks in advance
Ulrich
Hi, this works:
http://gatling.io/docs/2.0.0-RC2/http/http_protocol.html#bootstrapping
but looking at the next section we may need to update the example:
http://gatling.io/docs/2.0.0-RC2/http/http_protocol.html#base-url
setUp(scn.protocolConfig(httpConf)…)
16:01:36.436 [ERROR] i.g.a.ZincCompiler$ - x.scala:96: value protocolConfig is not a member of io.gatling.core.structure.PopulatedScenarioBuilder
16:01:36.438 [ERROR] i.g.a.ZincCompiler$ - scn.inject(i) .protocolConfig(httpConf)
16:01:36.438 [ERROR] i.g.a.ZincCompiler$ - ^
16:01:36.460 [ERROR] i.g.a.ZincCompiler$ - one error found
Indeed.
Just fixed it, thanks for reporting Alex !
Cheers,

Hanks Alex,
but how can i get rid of the compilation error?
Replace protocolConfig by protocols and it’ll compile (and works ;-))
Cheers,
Pierre
Nope

I use Gatling-RC2, GetDeviceScenario is a Singleton defined
Hi Pierre, unfortunately it does not compile.
Here comes a schematic of my code
package katwarn.gabriel
import io.gatling.core.Predef._
import io.gatling.http.Predef._
import scala.concurrent.duration._
class TestSimulation extends Simulation {
val userPerSecond : Int = 1
val duration : Int = 1
val url = http.baseURL("…")
val scn = scenario(“test”)
.feed(ssv("…").circular)
.exec(
http("…")
.get("/foo")
.headers(HeaderMapHelper.createHeaderMap(“HEAD”, null, “${foo}”, “${baz}”, “${bar}”))
.signatureCalculator(ProfileHmacSignatureCalculator)
.check(status.saveAs(“status”), status.in(Seq(200,404))))
setUp(scn.protocols(url).inject(constantUsersPersecond) during (duration seconds))
}
I still get “value protocols is not a member of io.gatling.core.structure.ScenarioBuilder”
Sorry, I forgot to mention that the call to protocols has to be after you configured your injection profile.
setUp(GetDeviceScenario.scn.inject(constantUsersPersecond).protocols(profileApi) during (duration seconds)) // compiles
For the record, that’s because protocols is defined on PopulatedScenarioBuilder, which is the what you get after you called inject(…) : https://github.com/gatling/gatling/blob/master/gatling-core/src/main/scala/io/gatling/core/structure/ScenarioBuilder.scala
Cheers,

Hi Pierre,
imho you made a typo - for me the following compiles
setup(GetDeviceScenario.scn.inject(constantUsersPerSec(userPerSecond) during (duration seconds)).protocols(profileApi))
Woops, my bad.
Indeed, in the middle of your injection profile definition, this wouldn’t work well…
Glad you got it working though
