JMeter json path assert json or array in the response

Question

I am doing api testing with Jmeter and using json path assertion to the response body. Problem is response body is giving two response path based on success and failure.

for failure

{
    "response": {
        "error_message": "Invalid input data.",
        "error_code": "Invalid_input",
        "error": true
    }
}

for success

{
    "response": [
        {
            "attachment_name": "num1.png",
            "attachment_id": 2547,
            "error": false
        },
        {
            "attachment_name": "num2.png",
            "attachment_id": 2548,
            "error": false
        },
        {
            "attachment_name": "num3.png",
            "attachment_id": 2549,
            "error": false
        }
    ]
}

Here am adding assertion on "error" path and value but the path changes on the result. Added $.response.error but this works only for failure case

Please help me to get correct path and assert in both the conditions. Thanks.

You can use deep scan operator .., the relevant JSON Assertion configuration would be something like:

whenever you get error JSON attribute with the value of true the Assertion will fail the relevant Sampler(s) in its scope

You can use regular expression for verifying both value (true or false) in the JSON Assertion.

A sample test plan is available for reference in GitHub

Hope this is useful.
