Using userId with Gatling DSL

I am using session.userId to parametrize my test requests like this:

exec(http("get request")
  .get((s:Session) => "somebaseUrl/" + s.userId.toString ))

Is it possible to get sesion userId differently, so my request addresses are more DRY, eg I won't have to use lambda?

I tried using gatling DSL: 

exec(http("get request")
  .get("somebaseUrl/${userId}")

but then I get: No attribute named 'userId' is defined error

I could just calculate some random id to my tests, but why when gatling already does this.

Only solution that I came up with is saving userId to some different attribute like this:

exec((s:Session) => s.set("user_id",s.userId)),
exec(http("test").get("${user_id}"))

but that doesn't seem right, and you have to make sure to call the set before all other requests.

Solution

  • The userId is some internal details. Gatling Expression language only exposes Session attributes, ie the attributes Map content.

    Either use the first way you described, with a function, or don't use Gatling internals and set your own UUID attribute (feeder, exec(function), etc).
