Turn off emails during testing

Is it possible to turn off sending emails when members signup?  I want to test acting as a new member but I cannot setup enough email ids.

Hello

I don't really understand the problem you are having. If you don't want the system to send emails, just go to System -> Global Configuration, look at Server tab, set Send Mail parameter to No and no email will be sent

But look like you want to ask something different?
