Look inside

BestInsurance has an online portal with a newly built application for providing features it hopes will attract new customers. As a backend developer for the insurance company, it’s your job to implement create, read, update, and delete (CRUD) services that allow front-office staff to manage and query data as needed to perform their daily tasks. You’ll define your CRUD API, using Spring Web and the DTO pattern, and observe your components in action. Leveraging inheritance and generic types in Java, you’ll refactor the code as necessary and complete the implementation of your RESTful APIs. To ensure your solution meets BestInsurance’s high standards, you’ll test the services with Spring Test and MockMvc.

This project is designed for learning purposes and is not a complete, production-ready application or solution.
