how do I test my new reader is working without making a real sale?

Hmm. If you want to make sure your reader can accept cards, then you can swipe one but not complete or cancel the transaction.

After inputting a dollar figure and choosing your payment method you have to additionally hit charge or tender (if taking cash) before the sale goes through.

If you can spare a buck you can always complete a full transaction for $1 (the least you can charge), let it process and then refund it back to yourself so you know how that process works as well.

The answer from @HeyItsMuff is right on, @jean.

First off, thanks for signing up for Square! Once you run your $1 payment as a test, like you heard, you can issue a refund (back to your card or just to balance your books, if it's cash). Here's the step-by-step: https://squareup.com/help/article/5060

Then you should be up and running!
