How to Run Tests

• CLI - gradlew :cleanTest :test --tests "com.gildedrose.GildedRoseTest.foo"
• Intellij
  • Tasks: :cleanTest :test
    
  • Arguments: --tests "com.gildedrose.GildedRoseTest.foo"

The 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.

New Requisites

• 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
• Conjured" items degrade in Quality twice as fast as normal items

Restrictions

• Do not alter the Item class or Items property
• 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.
