In this world of technology, meaningful and understandable software can be controlled easily. While designing the application's architecture, loose coupling between the services is necessary, meaning services should behave as a standalone application. This kind of architecture is called service-oriented architecture because, in this architecture design, we mainly focus on designing separate services and using them to make the whole application.

Today, API-driven microservices applications are a source of speed to innovation and competitive advantage – according to SmartBear’s most recent State of Software Quality – API report: However, this modern way of architecting software doesn’t come without challenges. Neglecting to adapt a new approach to service architecture design with a new approach to the underpinnings – API design and testing – can undermine the efforts.
