Iteration 1

Start with the three existing tests, and then use TDD to create a Room class that responds to the following interaction pattern:

pry(main)> require './lib/room'
#=> true

pry(main)> room = Room.new(:bedroom, 10, "13")
#=> #<Room:0x00007fa53b9ca0a8 @category=:bedroom, @length=10, @width="13">

pry(main)> room.category
#=> :bedroom

pry(main)> room.area
#=> 130

pry(main)> room.is_painted?
#=> false

pry(main)> room.paint

pry(main)> room.is_painted?
#=> true

Iteration 2

Use TDD to create a House class that responds to the following interaction pattern:

Note: Where you see something like #<House:0x00007fccd30375f8...>, this is shorthand for a full house object with that object identifier - we have replaced any attributes with ... for readability.

pry(main)> require './lib/room'
#=> true

pry(main)> require './lib/house'
#=> true

pry(main)> house = House.new("$400000", "123 sugar lane")
#=> #<House:0x00007fccd30375f8...>

pry(main)> house.price
#=> 400000

pry(main)> house.address
#=> "123 sugar lane"

pry(main)> house.rooms
#=> []

pry(main)> room_1 = Room.new(:bedroom, 10, '13')
#=> #<Room:0x00007fccd29b5720...>

pry(main)> room_2 = Room.new(:bedroom, 11, '15')    
#=> #<Room:0x00007fccd2985f48...>

pry(main)> house.add_room(room_1)

pry(main)> house.add_room(room_2)    

pry(main)> house.rooms
#=> [#<Room:0x00007fccd29b5720...>, #<Room:0x00007fccd2985f48...>]

Iteration 3

Use TDD to update your House class so that it responds to the following interaction pattern.

There are 4 methods in iteration 3:

A house is #above_market_average? if its price is greater than $500,000.
A house can list its #rooms_from_category by taking a symbol of the room, and returning the instances of the matching rooms.
A house can calculate its #area by adding together the areas of its rooms.
A house's #details should return a Hash of its attributes (price and address).

pry(main)> require './lib/room'
#=> true

pry(main)> require './lib/house'
#=> true

pry(main)> house = House.new("$400000", "123 sugar lane")
#=> #<House:0x00007fccd30375f8...>

pry(main)> house.above_market_average?
#=> false

pry(main)> room_1 = Room.new(:bedroom, 10, '13')
#=> #<Room:0x00007fccd29b5720...>

pry(main)> room_2 = Room.new(:bedroom, 11, '15')    
#=> #<Room:0x00007fccd2985f48...>

pry(main)> room_3 = Room.new(:living_room, 25, '15')
#=> #<Room:0x00007fccd383c2d0...>

pry(main)> room_4 = Room.new(:basement, 30, '41')
#=> #<Room:0x00007fccd297dc30...>

pry(main)> house.add_room(room_1)

pry(main)> house.add_room(room_2)    

pry(main)> house.add_room(room_3)

pry(main)> house.add_room(room_4)

pry(main)> house.rooms_from_category(:bedroom)
#=> [#<Room:0x00007fccd29b5720...>, #<Room:0x00007fccd2985f48...>]

pry(main)> house.rooms_from_category(:basement)
#=> [#<Room:0x00007fccd297dc30...>]

pry(main)> house.area
#=> 1900

pry(main)> house.details
#=> {"price" => 400000, "address" => "123 sugar lane"}

Iteration 4

Use TDD to update your House class so that it responds to the following interaction pattern:

There are 3 methods in iteration 4:

A house can calculate its price_per_square_foot by dividing its price by its area.
A house can return a list of rooms_sorted_by_area where the room instances returned are listed from greatest area to least area.
#rooms_by_category returns a hash where the keys are symbols of each room category, and the values are a collection of room instances that match the category.
