testing facebook like button offline

Is there a way to test what information is being sent to the like button while my site is still offline? At the mom开发者_运维技巧ent, the like button shows up but pressing it produces an error, I can't test if the right info is going to be passed to facebook once the implementation goes live.

If you put your app in "sandbox" mode, then it remains offline for all but the registered developers for it. That will allow you to test it, whilst stopping others from seeing it.
