When it comes to testing your push configuration and messages for quality assurance (QA) purposes, we recommend that you keep separate development/test and production workspaces — especially if they don’t share configuration credentials.

This often has the same certification credentials as your production environment. We still recommend setting up a separate test workspace with the “Send to sandbox” option turned on:
To send any type of test message, you’ll need a device token. Here’s how to find one.
Once you have a device token, if you want to test if your push setup is working, we recommend that you send this message from the configuration page:
