Test Cheap, Code Simple

(a.k.a. Pragmatic Unit Testing Now!)

This the sample project for the workshop, in C# / .NET Core.

TL;DR if you can run dotnet test and see tests pass then chances are you are all set.

Be warned: the code in this project may change from time to time and workshop to workshop (possibly just very slightly and the gist should stay the same).

Prerequisites

• .NET Core
• Git
• an IDE to work with, e.g. Visual Studio Code
• ... and an open mind :)

The example - a shopping service

A contrived shopping service that works as follows,

1. accepts a BuyRequest
2. calculates and applies discounts
3. charges member the discounted price

How discounts are calculated

• if member is having a birthday, then a certain discount is given
• if promo code "AM" is presented and checkout time is AM then a discount is given
• similarly for promo code "PM"
• only some items are discountable
• the higher discount applies if an item qualifies for more than one types of discounts

The goal of the workshop

• halve the code for this project
• happily write simple code and cheap unit tests, and benefit now! Not later
• and some more excitement

Enjoy coding! :)
