This Kata has been designed as a final hands-on exam for undergraduate students at IUT Charlemagne.
It borrows many ideas from Gilded Rose and Trip Service.
Kudos to Emily Bache and Sandro Mancuso for these amazing kata !

Welcome to Smart Stuff Society !

You are now in charge of our SmartFridge™ internal software. Your job is to implement the next update, detailed in the todo section.
The original developper left few weeks ago, telling us "the code is a little messy" so feel free to refactor it as you wish !
However, you MUST NOT change the files in the protocol subpackage.

• every day, the fridge run the following routine
  • scan every new products
  • update the freshness of all products
  • destroy all expired products (freshness <= 0)
• freshness update is done according to the following rules
  • for type eternal, it never decreasess
  • for type yogourt, it decreasess by 5% per day
  • for type vegetable, it decreasess randomly by 20% to 25% per day
  • for type mushroom, it decreasess by 10% per day while it is greater than 50%, and then decreases by 5% per day
  • for type meat, it decreases by 10% per day during a random number of days between 3 and 5, and then decreases by 20% per day
  • for others type, it decreases randomly by 5% to 15% per day
• the fridge also has the following features:
  • list all the products expiring tomorrow
  • list all the products with a set of tags
• the fridge is supplied with our SmartRecognitionEngine™, which gives these informations when detecting new products
  • a name
  • a type of product (e.g. meat, vegetable, fruit...)
  • a set of tags (e.g. sweet, salty, healthy, organic...)

Our customers reported that the fridge quickly becomes slow and needs frequents reboot since the meat update, you need to investiguate !

We want to introduce two new types with the following rules

• type egg, freshness decrease by 3% per day
• type fruit, freshness decreases by 5% per day while it is greater than 60%, and then decrease by 15% per day
