title: POSTMAN - Schema validation is passed even for bad response data
body: <p>tests["Valid schema"] = tv4.validate(jsonData, schema); is passed even if "error" and "responseType" is missing in the schema. How to make sure that response and schema both are matching for JSON schema.</p>
  
  <p>when I hit post request on postman, the following is the Response Body in postman</p>
  
  <pre><code>{  
    "statusCode": 400,
    "error": "Bad Request",
    "message": "Email/Phone number not found",
    "responseType": "EMAIL_NOT_FOUND",
    "arabicMessage": "البريد الإلكتروني / رقم الهاتف غير موجود"
    }
  </code></pre>
