Settlement Service

Prerequisites

• Dotnet 9.0 SDK
• nix | nix-darwin (Optional, if you want to run nix-shell)
• just (Optional, if you want to run automate task)

Demo Testing Note

I already create a hack to mimic InMemoryDatabase behavior that clear everything on shutdown.

Sample Request:

POST http://localhost:5209/api/Settlement

Sample Request Body

{ "bookingTime": "09:00", "name": "John Doe" }

Name value: is enforce to fullname with firstname and lastname.

Implementation Note:

My implementation focusing on showcase Domain Driven Design, application architecture design pattern and my prefer coding style. I like to design rich model with enforce business domain constraint instead of creating anemic model that would do every on fat service layer. I do left some comment on Domain model class where I explain some of my thought process.

I hope you have a great time exploring the project, I'm surely enjoy creating this project from scratch !

SQL

I implement ApplicationDbContext with SQLite since I want to build a complex EF core entity configuration. Since InMemoryDatabase does not support migration.

Auth

I didn't implement Auth since we would use a library like Auth0 or Azure AD to make authenticate and authorize.

Caching

I didn't implement Caching which is a necessary in real-world application. Since in this example we didn't focus on the retrieval of data in the application.

Future Work

Docker support

Testcontainer

In a real project I would love to test out Testcontainer for reliable testing. Since in that pass I face an error on production that does not occur in testing with InMemoryDatabase
