GoURL Bitcoin for WordPress – How to test Bitcoin payments?

Hi,

I am using [Official GoUrl Bitcoin Payment Gateway for WordPress].

After implementing the steps I can see the QR code form for Bitcoin payment. But I want to test the working for this I need a sandbox like environment as I do not want make real payments while development of website.

Is there any such facility?
If yes, please guide me to right direction.
If no, then please confirm.

Thanks
