Creating a dummy account so that you can fully test your programs is very easy. You can actually use your regular email address to create your dummy account.
By adding a "+" and some text between the local and domain parts of your email address, you can create a dummy email address.
Regular Email: email@example.com
Dummy Email: firstname.lastname@example.org
The emails will all go to your regular email inbox, but the SmarterSelect system recognizes them as two different emails, thus allowing you to open a dummy account to fully test your application.
Please note that this may not work with all email domains. For example, while this does work for Gmail, it does not work for Yahoo.
