Selecting random attribute from list captured via check.(jsonPath("$..attribute").findAll.saveAs

[mlastephenw...@gmail.com]

Hi,

I have an issue where I when I've captured  a list of all values returned for 4 attributes in an http response:

    .exec(http("addPosition")

      .post(baseUrl + "/url/getManagePositionByARVAAjax?organisationId=${userOrgIDParam}&isARAVA=false&screenContext=OWN")

      .headers(baseHeaders)

      .headers(headers_21)

      .check(status.is(200))

      .check(jsonPath("$..positionUuid").findAll.saveAs("positionUuidParamList"))

      .check(jsonPath("$..positionId").findAll.saveAs("positionIdParamList"))

      .check(jsonPath("$..positionName").findAll.saveAs("positionNameParamList"))

      .check(jsonPath("$..orgCodeId").findAll.saveAs("orgCodeIdParamList"))

     )

So say if there are a list of 20 values for each attribute, I want to select randomly, say value 5, for all 4 attributes to use in the next http Post, meaning that I can't use the ${Attributename.random()} function. How do I do that? Any help would be greatly appreciated.

    .exec(http("createPositionAssignment")

      .get(baseUrl + "/url/getServerTime?_=${serverTimestamp}")

      .headers(headers_10)

      .resources(http("createPositionAssignmentRequest")

      .post(baseUrl + "/url/createPositionAssignmentRequest ")

      .headers(baseHeaders)

      .headers(headers_21)

      .headers(headers_19)

      .formParam("applicantNotes", "")

      .formParam("positionExists", "true")

      .formParam("userPositions", "[]")

      .formParam("userName", "${firstNameParam} ${lastNameParam}")

      .formParam("userUuid", "${newUserUUID}")

      .formParam("workListId", "${workListIdParam}")

      .formParam("workListOrgId", "")

      .formParam("workListOrgCode", "")

      .formParam("workListOrgName", "")

      .formParam("requestType", "OWN")

      .formParam("organizationId", "${orgIDParam}")

      .formParam("changedOrgId", "")

      .formParam("withOutPermission", "false")

      .formParam("proceedWOSponsorApproval", "true")

      .formParam("userPositionVO[0].startDate", "${dateString}")

      .formParam("userPositionVO[0].endDate", "${dateStringPlusTen}")

      .formParam("userPositionVO[0].usersPositionId", "")

      .formParam("userPositionVO[0].positionName", "${positionNameParam}")

      .formParam("userPositionVO[0].positionUuid", "${positionUuidParam}")

      .formParam("userPositionVO[0].positionId", "${positionIdParam}")

      .formParam("userPositionVO[0].orgCode", "${orgCodeIdParam}")

      .formParam("userPositionVO[0].state", "New")

      .formParam("userPositionVO[0].source", "CareID")

      .formParam("userPositionVO[0].managedInId", "1")

      .formParam("userPositionVO[0].organizationId", "${orgIDParam}")

      .check(

            regex("SUCCESS").find(0).exists

              )

      .check(

            regex("code\":\"SUCCESS\",\"message\":\"(.*)\",\"category")

            .saveAs("requestIdParam")

              )

      ))

Thanks,

Steve

The simplest solution is probably to save the whole array in the session, then extract the fields of a random entry manually in a exec(function), like:

.check(jsonPath("$..array").ofType[Seq[Any]].saveAs("theArray"))

...

.exec { session =>

  for {

    array <- session("theArray").validate[Seq[Map[String, Any]]]

    entry = array(Random.nextInt(array.size))

  } yield session.setAll("positionUuid" -> entry("positionUuid"), "positionId" -> entry("positionId"))

}

Thanks Stephane,

That works, although I did have to amend the check slightly:

      .check(jsonPath("$[*]").ofType[Map[String,Any]].findAll.saveAs("theArray"))

Thanks for your help!
