Gilded Rose Kata in Ruby

Hi and welcome to team Gilded Rose. As you know, we are a small inn with a prime location in a prominent city run 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.

Our Current System

• All items have a days_remaining 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, unless legendary

• "Sulfuras", being a legendary item, never has to be sold or decreases in Quality. It never changes.

• "Backstage passes", like aged brie, increases in Quality as it's 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

Our Task

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

The specs are always the source of truth in this scenario. You'll start out with some failing and some passing specs.

Feel free to make any changes to the tick method and add any new code as long as everything still works correctly.

Requirements

• Make all specs pass
• Refactor giant if statements into something cleaner
• Show us what it's like to to work with you
• This is a chance to show some creativity and how you like to go about solving problems
• It's also an opportunity to show how you work with a team as you are welcome to ask questions and talk through ideas
