How to validate response in Postman?

Question

I am trying to validate response body including errors in postman. How can I validate the response and text below?

{
    "responseHeader": {
        "publisherId": "12345",
        "responseId": "abbcb15d79d54f5dbc473e502e2242c4abbcb15d79d54f5dbc473e502e224264",
        "errors": [
            {
                "errorCode": "1004",
                "errorMessage": "XXXX Not Found"
            }
        ]
    }
}

These are my tests which are failing:

tests['response json contains responseHeader'] = _.has(responseJSON, 'responseHeader');
tests['response json contains errors'] = _.has(responseJSON, 'responseHeader.publisherId');
tests["Response has publisher id"] = responseJSON.publisherId === 10003;

In the "Test" tab, parse your response body into an object, then use JavaScript to perform your tests.

var data = JSON.parse(responseBody);
tests["publisherId is 12345"] = data.responseHeader.publisherId === "12345";

Take a look at the test examples at the Postman site:
