Overview
Product summary
Review the store description, core capabilities, and common use cases.
When developing Shopify apps, you likely have to go through the checkout flow over and over again when making test purchases. Doing so manually consumes time and mind space.
CheckoutBreeze automates this process for you. It automatically fills in each field and completes your test order in seconds. It's fast and you don't have to think about it.
NOTE: CheckoutBreeze uses test credit cards provided by Shopify. It's not designed to make real purchases with real credit cards.
Requirements for the app to work:
* The store has test payments or the Bogus Gateway enabled
* Credit card or the Bogus Gateway is the default payment method of the store

Very useful extension. Saves me a minute every time I need to test my checkout flow, which is often.
This extension is amazing. In order to do development on my Shopify app, I have to checkout many times in order to test my app. After a while, this became a bigger and bigger waste of time. This app, save me a ton of time every time I begin developing. Very happy it was built. Thank You!!
