You just have to Git-clone and run (using Maven) this simple, stand-alone project: https://github.com/ptrthomas/karate-gatling-demo
Take the help of someone who knows their way around a Maven project if needed.
Once you get this running, you will be able to understand and modify this in no time.
package mock
import com.intuit.karate.gatling.PreDef._
import io.gatling.core.Predef._
import scala.concurrent.duration._
class CatsSimulation extends Simulation {
val protocol = karateProtocol(
"/cats/{id}" -> Nil,
"/cats" -> Nil
)
val create = scenario("create").exec(karateFeature("classpath:mock/cats-create.feature"))
val delete = scenario("delete").exec(karateFeature("classpath:mock/cats-delete.feature"))
setUp(
create.inject(rampUsers(10) over (5 seconds)).protocols(protocol),
delete.inject(rampUsers(5) over (5 seconds)).protocols(protocol)
)
}
