When testing the Track123 app on a Shopify development store, we encountered an issue where the app doesn't function correctly due to the store not being able to process real payments or real orders. This limitation prevents developers from fully exploring and verifying the app's functionality in a sandbox environment. We request the addition of a test mode or a development flag (e.g., test: true) that enables the app to simulate order tracking and all core features without requiring real transactions. This will allow full functionality testing within development stores, reduce dependency on customer support for test access, and improve developer experience and integration speed. Please consider implementing this to support smoother development and evaluation workflows for merchants and partners.
