WHAT IS HEADLESS COMMERCE?
Now that we know how the e-Commerce market is going to grow over a period of time, it’s time to discuss Headless Commerce.

Headless commerce is an e-commerce architecture which decouples the front end from the backend. In other words, it decouples the customer-facing front-end application of eCommerce from the backend system’s commerce functions and business logic.

Headless Commerce communicate or interact with many systems at various level of technology and it requires extensive levels of testing which can cover all aspect.

- User interfaces (UI) or presentation layer.

Typically testing can start from the Component level and APIs can be tested for each of these components. Reflect of data can be tested on UI, for example, if a payload value is changed how it reflects on the front-end if the content is changed from CMS then how it reflects on the front-end.
