Architecture Overview

This solution embodies clean architecture principles and follows the Domain-Driven Design (DDD) methodology.

Project Structure

Core Project

The Core project serves as the foundation, defining entities and encapsulating business logic pertaining to bank accounts and transactions.

UseCases Project

In the UseCases project, business use cases are implemented, orchestrating application behavior and interacting with Core entities.

Infrastructure Project

The Infrastructure project manages I/O devices, implementing database access, and a (fake) client to external web services. It acts as a bridge between the application and external systems.

Web Project

The Web project, a Web API, exposes three endpoints:

• GET /Accounts: Lists all accounts with their balances.
• GET /Accounts/{AccountId}: Returns a specific account with its balance and all associated transactions.
• POST /Accounts/{AccountId}/Transactions: Allows adding a transaction to a specific account. Hint: Transaction types are "Deposit" and "Withdrawal".

Test Projects

Three test projects facilitate comprehensive testing:

• Unit Tests: Focuses on testing the business logic and the use cases.
• Integration Tests: Group-tests features.
• Functional Tests: Verifies that the application functions correctly from an end-to-end perspective.

Dependency Diagram

Build

Prerequisites

Ensure you have .NET 8.0 SDK installed.

Build Steps

> dotnet build

Run

Prerequisites

Make sure you have the ASP.NET Core Runtime 8.0 installed. You already have it if you installed the SDK from the build step.

Run Steps

> cd src/ExaltIt.BankAccount.Web/
> dotnet run

an SQLite database "database.sqlite" and log files are generated in the web project when you run the application.

Test

To run tests (unit, integration, functional):

> cd tests/ExaltIt.BankAccount.<TestProject>/
> dotnet test
