Gatling check every value in array - scala

Question

I am writing gatling tests and using JSONPath $..parentId.
I am getting the response:
[
"102044",
"102044",
"102044"
]
I want to check that every value is equal to 102044. The amount of values can change.
By now I'm checking only random one:
#Then("then is successful")
override def thenStep(): Seq[HttpCheck] = {
var checks = List[HttpCheck]()
checks ::= status.is(session => 200)
checks ::= jsonPath("$..totalElements").ofType[Int].gt(8)
checks ::= jsonPath("$..totalElements").ofType[Int].lt(15)
checks ::= jsonPath("$.data[*].parentId").findRandom.is("102044")
checks
}
I tried to save the amount of values and the do something with it, like this:
checks ::= jsonPath("$..totalElements").ofType[Int].saveAs("all")
checks ::= jsonPath("$.data[*].parentId").findAll.is(Seq.fill(s"$all")("102044"))
But this is not working.
Is there a simple solution?
This question is similar to: In Gatling, how to iterate json array in .check to validate all values

Answer 1

What you should be able to do, using JMESPath is:
totalElements
To find the totalElements property of your JSON.
And
length(data[?parentId != '102044'])
To find if there are elements where the parentId is not 102044.
So, your assertions end up being be:
checks ::= jmesPath("totalElements").ofInt().gt(8)
checks ::= jmesPath("totalElements").ofInt().lt(15)
checks ::= jmesPath("length(data[?parentId != '102044'])").ofInt().is(0)
All this is based on the assumption that your input looks something like what you provided in your previous question:
{
"pageable": {
"currentPage": 1,
"totalPages": 1,
"pageSize": 20,
"last": true,
"first": true
},
"sort": {
"orders": [],
"sorted": false,
"unsorted": true,
"empty": true
},
"totalElements": 6,
"data": [
{
"id": 1,
"roleName": "test1",
"userCount": 5,
"parentId": "102044"
},
{
"id": 2,
"roleName": "test2",
"userCount": 5,
"parentId": "102045"
}
]
}
