Gilded Rose Requirements Specification
|
|
======================================
|
|
|
|
Hi and welcome to team Gilded Rose. As you know, we are a small inn with a prime location in a
|
|
prominent city ran by a friendly innkeeper named Allison. We also buy and sell only the finest goods.
|
|
Unfortunately, our goods are constantly degrading in quality as they approach their sell by date. We
|
|
have a system in place that updates our inventory for us. It was developed by a no-nonsense type named
|
|
Leeroy, who has moved on to new adventures. Your task is to add the new feature to our system so that
|
|
we can begin selling a new category of items. First an introduction to our system:
|
|
|
|
- All items have a `SellIn` value which denotes the number of days we have to sell the item
|
|
- All items have a `Quality` value which denotes how valuable the item is
|
|
- At the end of each day our system lowers both values for every item
|
|
|
|
Pretty simple, right? Well this is where it gets interesting:
|
|
|
|
[//]: # (- Once the sell by date has passed, `Quality` degrades twice as fast)
|
|
[//]: # (- The `Quality` of an item is never negative)
|
|
[//]: # (- "Aged Brie" actually increases in `Quality` the older it gets)
|
|
|
|
[//]: # (- The `Quality` of an item is never more than 50)
|
|
[//]: # (- "Sulfuras", being a legendary item, never has to be sold or decreases in `Quality`)
|
|
[//]: # (- "Backstage passes", like aged brie, increases in `Quality` as its `SellIn` value approaches;)
|
|
|
|
[//]: # ( `Quality` increases by 2 when there are 10 days or less and by 3 when there are 5 days or less but)
|
|
|
|
[//]: # ( `Quality` drops to 0 after the concert)
|
|
|
|
We have recently signed a supplier of conjured items. This requires an update to our system:
|
|
|
|
- "Conjured" items degrade in `Quality` twice as fast as normal items
|
|
|
|
Feel free to make any changes to the `updateQuality` method and add any new code as long as everything
|
|
still works correctly. However, do not alter the Item class or Items property as those belong to the
|
|
goblin in the corner who will insta-rage and one-shot you as he doesn't believe in shared code
|
|
ownership (you can make the `updateQuality` method and Items property static if you like, we'll cover
|
|
for you).
|
|
|
|
Just for clarification, an item can never have its `Quality` increase above 50, however "Sulfuras" is a
|
|
legendary item and as such its `Quality` is 80 and it never alters.
