How to run tests without buying the domain.

Hello everyone,
This is a newbie question here, so if it sounds silly please forgive me.... :slight_smile:

I installed the WHMCS provisioning plugin in my network and I am ready to run some tests to make sure that once the payment is cleared everything gets created and mapped right.
So, I was wondering if there is a way to test the mapping without having to buy the domains. Not trying to be cheap here..lol the word would be resourceful.
I don`t have any ideas on how to conduct some tests to make sure everything is talking to each other and ready to go.
Can anybody shine some light?

I appreciate your input.

Thanks
Davys
