Iteration 0 - Bug Fixing

There are some existing tests and classes, with 1 failing test. Make that test pass before moving on!

Iteration 1 - Items, Attendees & Auctions

Use TDD to create Item, Attendee, & Auction that will respond to the interaction pattern below:

Graded Functionality

1. Auction #add_item(item)
2. Auction #item_names

pry(main)> require './lib/item'
#=> true
pry(main)> require './lib/auction'
#=> true
pry(main)> require './lib/attendee'
#=> true

pry(main)> item1 = Item.new('Chalkware Piggy Bank')
#=> #<Item:0x00007fbda98fa1b0 @bids={}, @name="Chalkware Piggy Bank">

pry(main)> item1.name
#=> "Chalkware Piggy Bank"

pry(main)> item2 = Item.new('Bamboo Picture Frame')
#=> #<Item:0x00007fbda91874f0 @bids={}, @name="Bamboo Picture Frame">

pry(main)> attendee = Attendee.new({name: 'Megan', budget: '$50'})
#=> #<Attendee:0x00007fbda913f038 @budget=50, @name="Megan">

pry(main)> attendee.name
#=> "Megan"

pry(main)> attendee.budget
#=> 50

pry(main)> auction = Auction.new
#=> #<Auction:0x00007fbda90f1cc0 @items=[]>

pry(main)> auction.items
#=> []

pry(main)> auction.add_item(item1)
pry(main)> auction.add_item(item2)

pry(main)> auction.items
#=> [#<Item:0x00007fbda98fa1b0 ...>, #<Item:0x00007fbda91874f0 ...>]

pry(main)> auction.item_names
#=> ["Chalkware Piggy Bank", "Bamboo Picture Frame"]

Iteration 2 - Bidding!

Use TDD to update your classes to respond to the following interaction pattern. Some notes:

• unpopular_items are those items which have no bids.
• potential_revenue is the sum of each item's highest bid.

Graded Functionality

1. Item #add_bid(attenddee, bid_amount)
2. Item #current_high_bid
3. Auction #unpopular_items
4. Auction #potential_revenue

Iteration 3 - More bidding stuff!

Use TDD to update your classes to include the following functionality.

Graded Functionality You must complete at least 2 of the 3 methods to pass. If you have time, we suggest doing all 3.

Some notes:

• bidder_info should return a hash with keys that are attendees, and values that are a hash with that attendee's budget and an array of items that attendee has bid on.
• close_bidding should update the item so that it will not accept additional bids

Class	Instance Method Name	Return Value
Auction	bidders	Array of bidders' names as String; ex: ["Megan", "Bob", "Mike"]
Auction	bidder_info	Hash with the following format: key of Attendee object pointing to a value of a Hash. The subhash should have a key of :budget as a Symbol and value of their budget as an Integer. The subhash should have a second key of :items as a Symbol with a value that is an Array of items the attendee has bid on. See example below.
Item	close_bidding	Return value of your choice; ensure it follows the spec above such that closing the bidding on an item makes it so the item will no longer accept new bids.

Example return value hash for bidder_info

 #    #<Attendee:0x00007ff177a45108 @budget=50, @name="Megan"> =>
