How to validate dynamic values in postman

Question

I want to validate some mandatory fields in my JSON response body. Until now I am using a static way of testing by using hardcoded values something like this

json_response = JSON.parse(responseBody);
x=json_response
pm.expect(x).to.equal("abc"); 

But I want to rerun my test scripts so I don't want to change my tests again and again to validate the values. Could anyone please suggest how can I validate my response body.

{
    "Name": "John",
    "Contact number": 9826363660,
    "Address": "xyz"
}

As every time I will get new values in these keys "Names" "Contact number" "Address"

Answer 1

  pm.response.json().hasOwnProperty("Name")

You can use hasOwnProperty to check whether the field exists

Do schema validation

var schema = {
    type: "object",
    properties: {
        "NAME": {
            "type":"string"
        },
        "ADDRESS": {
            "type":"string"
        },
        "Contact Number": {
             "type":"number"
        }
    }

};

    
  pm.response.to.have.jsonschema(schema)
