Having extracted the App from github, perform the following steps to build, configure and execute the App:

mvn clean install

./mvnw spring-boot:run

• No Junit tests have been provided for the Domain classes as they are simple POJO (Getter and Setter) classes where testing adds no value.
• The Same applied to the Repository Tier Interfaces

Mock MVC Tests have been generated for the Web/Rest Tier, to exercise the REST API ( and subsequent tiers) , by using Mock API REST requests to emulate real REST requests to the API. Invoke the tests vai maven with;

mvn test

Postman has been used as the REST Client and the following requests were co figured for testing the api;

• POST to http://localhost:8080/accounts with JSON document body
• GET to http://localhost:8080/accounts/52
• POST to http://localhost:8080/transactions with JSON DTO document body

• OperationsTypes : Depending on the amount of Operations data that would be required and whether it would change dynamically this class could just be implemented as an Enum.
• Service Tier : Rest Controller classes delegates directly to a Repository Tier, as an intermediate 'Service' is not justified.

For further reference, please consider the following sections:

• Official Apache Maven documentation
• Spring Boot Maven Plugin Reference Guide
• Spring Web
• Spring Data JPA

The following guides illustrate how to use some features concretely:

• Building a RESTful Web Service
• Serving Web Content with Spring MVC
• Building REST services with Spring
