Placing a test order
By placing a test order, you can make sure that your checkout process and settings for order processing, inventory, shipping, email notifications, and taxes are all correct. You should place at least one test order during your store setup or whenever you make changes to your payment settings.
You can place a test order by simulating a transaction through Shopify's Bogus Gateway. If you're using Shopify Payments, then you can test your configuration by using Shopify Payments' test mode. You aren't charged for test orders placed through these gateways.
Test orders and simulated transactions don't display in your payouts or reports. You can test a payment gateway only after you've chosen a paid plan.
You can also process an order using a real payment provider, and then immediately cancel and refund the order. You might be subject to fees from the payment processor you use.
