The frontend is a Microservice Testing approach to front-end web development. The current trend is to build a powerful and feature-rich web application that resides on top of a Microservice architecture. Over time the Micro Frontend Architecture becomes a part of the application, often it is developed by a separate team, grows, and gets more difficult to maintain, this type of application is called Frontend Monolith. To solve this problem, the concept of the Micro Frontend came into the picture.
