在jmeter中使用groovy响应断言脚本的问题

Question

I want to write a code for Response assertion using groovy script , for the Response data like this:

[
    {
        "fieldId":"947bb60f",
        "id":"e7b8ad2b",
        "name":"field",
    }
]

Tried using the below groovy script for which i am getting error(failure message).

if (!jsonResponse.keySet().containsAll(["fieldId","id","name"] )) {
         failureMessage += "The json response body has wrong structure or error msg.\n\n";

}

The same script working fine with the single tree structure as below. Appreciate your help on this with groovy script .

[

  "fieldId":"947bb60f",
  "id":"e7b8ad2b",
  "name":"field",

]

Answer 1

So, you are getting a list of items returned (containing a single item)

Assuming you never expect more than one item, you can check the size of it with:

if (jsonResponse.size() != 1) {
     failureMessage += "Expected one item, got ${jsonResponse.size()}.\n\n";
}

Then, you can grab the first element with:

def jsonElement = jsonResponse[0]

And check the field names with:

if (jsonElement.keySet() != ["fieldId","id","name"] as Set) {
     failureMessage += "Unexpected fields in response ${jsonElement.keySet()}.\n\n";
}
