Banking Kata (.NET)

Purpose

This demo was created for the purposes of meetup series on TDD & Clean Architecture. See the YouTube Meetups. Please note that this project is purely for demo purposes only.

Introduction

This Banking Kata illustates the application of TDD and Clean Architecture with a Use Case Driven Approach in .NET.

The Use Cases are:

• Open Account
• Withdraw Funds
• Deposit Funds (pending)
• View Account (pending)

Prerequisites

.NET 6

Tool dotnet-ef needs to be installed:

dotnet tool install --global dotnet-ef

Installing Stryker:

dotnet tool install -g dotnet-stryker

Set Environment variables in Visual Studio for Optivem.Kata.Banking.Web:

1. Right-hand click the project Optivem.Kata.Banking.Web
2. Click on "Properties"
3. Select "Debug" from the left-hand side menu
4. Inside "General" click on "Open debug launch profiles UI"
5. In the section "Environment variables" input the following (feel free to adapt the SQL_SERVER_CONNECTION_STRING based on your local machine):

ASPNETCORE_ENVIRONMENT=Development,SQL_SERVER_CONNECTION_STRING=Data Source/=localhost;Initial Catalog/=BankingKata;Integrated Security/=True;MultipleActiveResultSets/=True;

For running the tests, the environment variable SQL_SERVER_CONNECTION_STRING needs to be configered in Solution Items > test.runsettings.

Inside Visual Studio, click on Test > Configure Run Settings > Select Solution Wide runsettings File, then select test.runsettings (note: this is temporary since I saw that Autodetect wasn't working, but I will try again to find a solution for Autodetect).
