CheckoutBreeze is a Chrome add-on developed by Niklas Wenzel that aims to simplify the process of test purchases for Shopify app developers. With this tool, developers can automate the checkout flow, saving time and effort.

By automatically filling in each field and completing the test order in seconds, CheckoutBreeze eliminates the need for manual input, allowing developers to focus on other tasks. The extension works seamlessly and requires no additional thinking or interaction.

It is important to note that CheckoutBreeze uses test credit cards provided by Shopify and is not intended for making real purchases with real credit cards. To ensure the app works properly, the store must have test payments or the Bogus Gateway enabled, and the default payment method should be a credit card or the Bogus Gateway.

In case of any issues, such as Shopify updates or A/B tests that break CheckoutBreeze, the developer suggests deleting site data for the shop or contacting them via email for assistance. Overall, CheckoutBreeze offers a convenient solution for automating test purchases on Shopify.
