Assertions: Json Schema complaince

This url can be any normal url link which contains JSON schemas.

For example - http://example.com/docs/path/employee.json

Which contains the schemas like this:-

{
  "$id": "https://example.com/person.schema.json",
  "$schema": "http://json-schema.org/draft-07/schema#",
  "title": "Person",
  "type": "object",
  "properties": {
    "firstName": {
      "type": "string",
      "description": "The person's first name."
    },
    "lastName": {
      "type": "string",
      "description": "The person's last name."
    },
    "age": {
      "description": "Age in years which must be equal to or greater than zero.",
      "type": "integer",
      "minimum": 0
    }
  }
}

So, in your case, I guess, you cannot use this JSON Schema complaince. Since, you don't have the urls.

You can use JSON Path Assertions.
