GotheTollway

This repository contains the codebase for codetest.

Requirements

Each passage through a toll station in Gothenburg costs 8, 13, or 18 kronor depending on the time of day. The maximum amount per day and vehicle is 60 kronor. Congestion tax is collected for vehicles passing through a toll station Monday to Friday between 06:00 and 18:29. Tax is not collected on Saturdays, holidays, days before holidays, or during the month of July. Some vehicles are exempt from congestion tax. A car passing through multiple toll stations within 60 minutes is only taxed once. The amount to be paid is then the highest amount among the passages.

Documentation

The idea of the application is that it should be a simple API that has two ways of communication:

1. Create a Tollpassage, regardless if there's a fee or not. This request and logic should only care to create the Tollpassage.
2. Create an Invoice. This is a GET method with its only purpose to get a specific car's all passages and total sum of fees.

Codewise, I have used the repository pattern and Entity Framework to create an easy way to store and retrieve data based on the different exemptions.

Structure

• API: The API that's exposed to the "public".
• Domain: Holds all entities, interfaces, business logic, and some helper classes.
• Contract: Holds all the models that are used for the API to isolate the domain entities and not expose them.
• Infrastructure: Holds the needed logic to request other services (internally and externally if needed).

I have also tried to cover as much code with tests as possible. (There are some tests left to do).

Good to know

If you want to try this, all you need to do is run 'update-database -Context GotheTollwayContext'. You can use whatever type of Swedish registration number that's valid to test. Using the 'CreateInvoice' function will give you the data for each vehicle.

What I wished have done differently:

Can explain during the meeting and presentation.
