How to add Facebook Credits to test user

I created a Facebook test user for my Lovers Facebook application, and I'm using this user to test the Facebook Credits API. But, when I click the lin开发者_高级运维k to make an order, I am presented with a Facebook Dialog titled, "Buy Red Rose" I'm asked for my credit card info because the test user doesn't have enough credits. How do I add Facebook credits to a test user

Found it. No need to create a test user. You can just add your user id in the text field labeled Credits Test Users on the Credits tab of the Edit Application Settings page => http://www.facebook.com/developers/editapp.php?app_id=YOUR_APP_ID
