@fuergaosi233 - Thanks so much for the contribution!!! This overall looks good and ready to submit but was wondering if you could add in a unit test using the schema option with something other than public so it validates that it works.

Let me know if you need help.

@fuergaosi233 - just following up if you can get a couple updated unit tests in for this new option.

[fuergaosi233]

Ok, I'll try that
