Json Extractor in JMeter

Question

I am using JSON extractor in JMeter. Below is my Response Body. I am using the Json path expression to capture the value, which is working fine.

Apart from the above condition, I need to add one more condition.

If the "travelID" length is equal to 33, then only I need to get the BoundID.

Example : AAA-AB1234-AAABBB-2022-11-10-1111

Total length or count of the above travelID is 33, but sometime I used to get 31,32 also but I need to capture the Bound ID only when the length is 33. Is that feasible ? Please help on the same PFB sample response body.

                        }
                    ]
                },

                            }
                        ]
                    }
                ]
            }
        ]
    },

        }
    ]
}

Answer 1

I don't think it's possible with JSON Extractor, I would rather suggest going for JSR223 PostProcessor and the following Groovy code:

def BoundId = new groovy.json.JsonSlurper().parse(prev.getResponseData())
        .data.RenewalDetails[0].Itemdetails.find { itemDetail ->
    itemDetail.availabilityDetails[0].travelID.length() == 33
}?.BoundId


vars.put('BoundId', BoundId ?: 'Not Found')

You will be able to refer extracted value as ${BoundId} later on where required.
