How to identify the specific true or false value from json assertion using jmeter?

Question

The requirement is we have to identify "elements" and then check if its true or false.

{
    "first": {
        "second": [
            {
                "element": 1,
                "elementrec": null,
                "enabled": true,
                "rec": null
            },
            {
               "element": 2,
                "elementrec": null,
                "enabled": false,
                "rec": null
            },
            {
                "element": 3,
                "elementrec": [
                    "3"
                ],
                "enabled": true,
                "rec": [
                    "3"
                ]
            }
        }
      ]
    } 
}

Above 3 element has either true or false. Would like to identify all 3 elements for true or false using different json assertion.

I don't know what do you mean by "identify", there are too many possible options so I'll come up with the shortest one:

1. Add JSR223 PostProcessor as a child of the request which returns the above JSON

2. Put the following code into "Script" area

   new groovy.json.JsonSlurper().parse(prev.getResponseData()).first.second.each { item ->
       log.info('Element: ' + item.element + ', enabled: ' + item.enabled)
   }
   

3. Run your test

4. In jmeter.log file you will see "elements" with their "enabled" status
