Demo Google Accounts for App Testing?

I'm working on an openid login system for an app I'm building and I'm wondering if anyone has ever heard of a "dummy" Google Account for testing?

I have my own Google account that I've used, but I want to make 开发者_如何学Gosure it's working with different users.

So, I'm wondering if Google provides a few accounts for this purpose?

I'd rather not sign up my own "dummy" accounts, but it might be my only choice.

Thanks! Troy
