What Is a Test Order?
A test order is an order placed on your online store to validate that your checkout procedure and inventory, shipping, order processing, taxes, and email notification settings are all proper.
A test order is recommended by eCommerce systems. Toko also advises business owners to place at least one test order when setting up their store or changing their payment methods.
To conclude, you should do a test buy before launching your general or niche-based store to ensure a smooth and successful transaction.
