asLongAs timeout

[Cedric Cazin]

Hello all

I have done something like that

  .exec { session => session.set("status", "In progress") }

.asLongAs(session => session("status").as[String].equals("In progress")) {

exec(

_GetStuff // call http to a webservice to get a json

.check(jsonPath("""$.finalStatus""").ofType[String].saveAs("status"))

.check(jsonPath("""$.finalStatus""").ofType[String].not("Error"))

)

.pause(4 seconds)

}

I did not anticipate is that sometime the backend will never update a status, so always "In progress"

Is there a way to have a max try on this or another method ? 

I checked poll but not sure how to have a timeout too..

And yes I will fix the backend too ;)

Cheers

Have you tried  tryMax ?  Ref.  http://gatling.io/docs/current/general/scenario/

Hi 

Thanks for the answer

I tried but I have some condition to failed the scenario, and I cannot figure out how to do it.

here is an example, THE CHECK ARE NOT REAL CODE, but rather a way to explains my different conditions :)

  .exec(http.post(publishsomething))                                                                           // publish something 

  .check(jsonPath("""$.taskId""").ofType[String].saveAs("taskId"))                              // get the task id of the backend background task

.tryMax(300) {                                                                                                           // try max 5 minutes

exec(

http.get(get taskId status)                                                                          // call http to a webservice to get a json

.check(jsonPath("""$.finalStatus""").ofType[String].is("Done"))                  >>  should exit the tryMax block and continue the 

.check(jsonPath("""$.finalStatus""").ofType[String].is("Error"))                   >>  should exit the tryMax block and failed the scenario

                                .check(jsonPath("""$.finalStatus""").ofType[String].is("In progress"))         >>  should continue the tryMax block 

)

.pause(1 seconds)

}

any ideas ?

Thanks

I don't want to muddy the waters further, but one _untested_ idea might be something like:

.exec { session => session.set("counter", 0) }
.asLongAs(session => session("counter").as[Int] < 300) {

  .exec(http.get(get taskId status)

  .doSwitch("${status}") (
    "Error" -> handleError,
    "Done" -> publishingComplete
    /* "In progress" is not matched, so the switch is bypassed */
  )

  .pause(1 second)
  .exec { /* increment the counter */ }
}

where you'd need to create handleError and publishingComplete elsewhere to handle those conditions.   Good luck.

Thanks Nige

But what I cannot find in the Doc, Group, google...

is how handleError can stop the current scenario session with KO
