I'm trying to modularise a series of performance tests in Gatling.
Several of the tests execute the same initial path through the pages, so I thought that I could break them down into a series of scenarios, each scenario being a series of shared actions defined in its own file, and then a final Simulation definition that simply executed the specified scenarios one after the other.
What I then need is for my Simulation to run those scenarios in sequence; but I can only find how to run them either concurrently, or with a specified delay between each. Is there any Simulation setup option to run the defined scenarios one after the other without specifying an arbitrary delay?
EDIT
Currently, I have the following set of files:
homepageHeaders.scala
package advanced
object homepageHeaders {
val homepage_headers_1 = Map(
"Accept" -> """text/html,application/xhtml+xml,application/xml;q=0.9,*/*;q=0.8""",
"If-Modified-Since" -> """Wed, 20 Mar 2013 15:36:31 +0000""",
"If-None-Match" -> """"1363793791""""
)
}
homepageChain.scala
package advanced
import com.excilys.ebi.gatling.core.Predef._
import com.excilys.ebi.gatling.http.Predef._
import com.excilys.ebi.gatling.jdbc.Predef._
import akka.util.duration._
import homepageHeaders._
object homepageChain {
val homepageChain =
//Homepage
exec(http("homepage")
.get("/")
.headers(homepageHeaders.homepage_headers_1)
)
}
pageHeaders.scala
package advanced
object pageHeaders {
val page_headers_1 = Map(
"Accept" -> """text/html,application/xhtml+xml,application/xml;q=0.9,*/*;q=0.8"""
)
}

object pageChain {
val pageChain =
//Page Menu
exec(http("page request")
.get("/page1")
.headers(pageHeaders.page_headers_1)
)
}
pageSimulation.scala

class pageSimulation extends Simulation {
val urlBase = "http://www.mytestsite.com"
val httpConf = httpConfig
.baseURL(urlBase)
.acceptHeader("image/png,image/*;q=0.8,*/*;q=0.5")
.acceptEncodingHeader("gzip, deflate")
.acceptLanguageHeader("en-gb,en;q=0.5")
.userAgentHeader("Mozilla/5.0 (Windows NT 6.1; WOW64; rv:17.0) Gecko/20100101 Firefox/17.0")
val pageScenario = scenario("Bodycare Scenario")
.exec(homepageChain.homepageChain)
.exec(pageChain.pageChain)
setUp(
homepageScenario.users(1).protocolConfig(httpConf)
)
}
The error that I'm getting is:

Clearly I'm missing something in my definition, but I just don't understand what it is
You can compose chains, not scenarios.
For example:
val login = exec(...)...
val foo = exec(...)...
val bar = exec(...)...
val scn1 = scenario("Scenario1").exec(login).exec(foo)
val scn2 = scenario("Scenario2").exec(login).exec(bar)
Clear?
