This will be useful to detect cases where for instance, doesn't have a default response, and the response status "mistakenly" uses a status code that is not defined in the specs.

At OperationValidator.validateBody, if it doesn't find a response validator, it stops without error. It will be interesting to have the option (via parameter/flag) to raise an exception if the status code is not in the specs.

Right now as a workaround I doing that validation beforehand (similar to getResponseValidator) what becomes redundant when it rechecks the body. Also, if has any other option that has a similar effect, please let me know.
