Iteration 1

Use TDD to create a Ride and a Attendee class that respond to the following interaction pattern:

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

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

pry(main)> ride = Ride.new({name: 'Ferris Wheel', cost: 0})
#=> #<Ride:0x00007ff88ea3fc30...>

pry(main)> ride.name
#=> "Ferris Wheel"

pry(main)> ride.cost
#=> 0

pry(main)> attendee = Attendee.new('Bob', 20)
#=> #<Attendee:0x00007ff88ea979a8...>

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

pry(main)> attendee.spending_money
#=> 20

pry(main)> attendee.interests
#=> []

pry(main)> attendee.add_interest('Bumper Cars')

pry(main)> attendee.add_interest('Ferris Wheel')

pry(main)> attendee.interests
#=> ["Bumper Cars", "Ferris Wheel"]

Iteration 2

Use TDD to create a Carnival class that responds to the following interaction pattern. For the recommend_rides method, the Carnival should recommend rides that match an Attendee's interests.

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

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

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

pry(main)> jeffco_fair = Carnival.new("Jefferson County Fair")
#=> #<Carnival:0x00007fe593a28728...>

pry(main)> jeffco_fair.name
#=> "Jefferson County Fair"

pry(main)> jeffco_fair.rides
#=> []

pry(main)> ferris_wheel = Ride.new({name: 'Ferris Wheel', cost: 0})
#=> #<Ride:0x00007fe59506ede8...>

pry(main)> bumper_cars = Ride.new({name: 'Bumper Cars', cost: 10})
#=> #<Ride:0x00007fe594851930...>

pry(main)> scrambler = Ride.new({name: 'Scrambler', cost: 15})
#=> #<Ride:0x00007fe59314eb98...>

pry(main)> jeffco_fair.add_ride(ferris_wheel)

pry(main)> jeffco_fair.add_ride(bumper_cars)

pry(main)> jeffco_fair.add_ride(scrambler)

pry(main)> jeffco_fair.rides
#=> [#<Ride:0x00007fe59506ede8...>, #<Ride:0x00007fe594851930...>, #<Ride:0x00007fe59314eb98...>]

pry(main)> bob = Attendee.new('Bob', 20)
#=> #<Attendee:0x00007fe59507dc80...>

pry(main)> sally = Attendee.new('Sally', 20)
#=> #<Attendee:0x00007fe593ac3318...>

pry(main)> bob.add_interest('Ferris Wheel')

pry(main)> bob.add_interest('Bumper Cars')

pry(main)> sally.add_interest('Scrambler')

pry(main)> jeffco_fair.recommend_rides(bob)
#=> [#<Ride:0x00007fe59506ede8...>, #<Ride:0x00007fe594851930...>]

pry(main)> jeffco_fair.recommend_rides(sally)
#=> [#<Ride:0x00007fe59314eb98...>]

Iteration 3

• Use TDD to update your Museum class so that it responds to the following interaction pattern.
• For attendees_by_ride_interest, this method takes no arguments and returns a Hash where each key is a Ride. The value associated with that Ride is an Array of all the Attendees that have an interest in that ride.
• ticket_lottery_contestants returns an array of attendees that do not have enough money to go on a particular ride, but are interested in that ride. The lottery winner is generated randomly based on the available contestants when draw_lottery_winner is called.
• You will need to use a stub to test the announce_lottery_winner method in conjunction with the draw_lottery_winner method. JOY!

#=> nil

#If no contestants are eligible for the lottery, nil is returned.

pry(main)> jeffco_fair.announce_lottery_winner(scrambler)
#=> "Bob has won the IMAX exhibit"

#We realize that, in this setup, Bob is not interested in the scrambler.  However, in your test, the result should match exactly.  You will need to stub the return of `draw_lottery_winner` as the above method should depend on that method :)

pry(main)> jeffco_fair.announce_lottery_winner(ferris_wheel)
#=> "No winners for this lottery"

#If there are no contestants, there are no winners.

Iteration 4

Use TDD to update your Carnival class to add the following functionality:

• When an Attendee is admitted to the Carnival, they go on Rides. The Rides that an Attendee goes on follows these rules:
• An Attendee will only go on Rides they are interested in
• An Attendee will got on a Ride with a higher cost before a Ride with a lower cost.
• If an Attendee does not have enough spending_money to cover the cost of the Ride, they will not go on the Ride.
• When the Attendee goes on a Ride, the cost of the Ride should be subtracted from their spending_money and added to the Carnival revenue.
• A Carnival should have a attendees_of_rides method that returns a Hash where the keys are the Rides and the values are Arrays containing all the Attendees that go on that Ride.
• A Carnival should have a method revenue that returns an integer representing the revenue collected from Attendees going on Rides.

The Carnival class should respond to the following interaction pattern:
