Iteration 1

Use TDD to create a Boat and a Renter class that respond to the following interaction pattern:

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

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

pry(main)> kayak = Boat.new(:kayak, 20)    
# => #<Boat:0x00007fceac8f0480...>

pry(main)> kayak.type
# => :kayak

pry(main)> kayak.price_per_hour
# => 20

pry(main)> kayak.hours_rented
# => 0

pry(main)> kayak.add_hour

pry(main)> kayak.add_hour

pry(main)> kayak.add_hour

pry(main)> kayak.hours_rented
# => 3

pry(main)> renter = Renter.new("Patrick Star", "4242424242424242")    
# => #<Renter:0x00007fb5ef98b118...>

pry(main)> renter.name
# => "Patrick Star"

pry(main)> renter.credit_card_number
# => "4242424242424242"

Iteration 2

Use TDD to create a Dock class. It should have the following methods:

rent - this method takes a Boat and a Renter as arguments. Calling this method signifies that the Boat has been rented by the Renter.
rental_log - this method returns a hash that associates a Boat with the Renter that rented it.

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

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

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

pry(main)> dock = Dock.new("The Rowing Dock", 3)    
# => #<Dock:0x00007fdeedb0a788...>

pry(main)> dock.name
# => "The Rowing Dock"

pry(main)> dock.max_rental_time
# => 3

pry(main)> kayak_1 = Boat.new(:kayak, 20)
# => #<Boat:0x00007fdeedb3a528...>

pry(main)> kayak_2 = Boat.new(:kayak, 20)    
# => #<Boat:0x00007fdeedae1860...>

pry(main)> sup_1 = Boat.new(:standup_paddle_board, 15)
# => #<Boat:0x00007fdeedaa8bc8...>

pry(main)> patrick = Renter.new("Patrick Star", "4242424242424242")    
# => #<Renter:0x00007fdeed0ab828...>

pry(main)> eugene = Renter.new("Eugene Crabs", "1313131313131313")    
# => #<Renter:0x00007fdeed8ce5c8...>

pry(main)> dock.rent(kayak_1, patrick)    

pry(main)> dock.rent(kayak_2, patrick)    

pry(main)> dock.rent(sup_1, eugene)    

pry(main)> dock.rental_log
# =>
# {
#   #<Boat:0x00007fdeedb3a528...> => #<Renter:0x00007fdeed0ab828...>,
#   #<Boat:0x00007fdeedae1860...> => #<Renter:0x00007fdeed0ab828...>,
#   #<Boat:0x00007fdeedaa8bc8...> => #<Renter:0x00007fdeed8ce5c8...>
# }

Iteration 3

Use TDD to implement a Dock#charge method:

This method takes a Boat as an argument
This method returns a hash with two key/value pairs:
- The key :card_number points to the credit card number of the Renter that rented the boat
- The key :amount points to the amount that should be charged. The amount is calculated by multiplying the Boat's price_per_hour by the number of hours it was rented. However, any hours past the Dock's max_rental_time should not be counted. So if a Boat is rented for 4 hours, and the max_rental_time is 3, the charge should only be for 3 hours.

The Dock class should respond to the following interaction pattern:

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

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

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

pry(main)> dock = Dock.new("The Rowing Dock", 3)    
# => #<Dock:0x00007fe2f71f4730...>

pry(main)> kayak_1 = Boat.new(:kayak, 20)
# => #<Boat:0x00007fe2f8074c38...>

pry(main)> kayak_2 = Boat.new(:kayak, 20)    
# => #<Boat:0x00007fe2f70e3e68...>

pry(main)> sup_1 = Boat.new(:standup_paddle_board, 15)    
# => #<Boat:0x00007fe2f80a6ee0...>

pry(main)> patrick = Renter.new("Patrick Star", "4242424242424242")    
# => #<Renter:0x00007fe2f787d700...>

pry(main)> eugene = Renter.new("Eugene Crabs", "1313131313131313")    
# => #<Renter:0x00007fe2f7829c68...>

pry(main)> dock.rent(kayak_1, patrick)

pry(main)> dock.rent(kayak_2, patrick)    

pry(main)> dock.rent(sup_1, eugene)    

pry(main)> kayak_1.add_hour

pry(main)> kayak_1.add_hour

pry(main)> dock.charge(kayak_1)
# =>
# {
#   :card_number => "4242424242424242",
#   :amount => 40
# }

pry(main)> sup_1.add_hour

pry(main)> sup_1.add_hour

pry(main)> sup_1.add_hour

# Any hours past the max rental time should not count
pry(main)> sup_1.add_hour

pry(main)> sup_1.add_hour

pry(main)> dock.charge(sup_1)
# =>
# {
#   :card_number => "1313131313131313",
#   :amount => 45
# }

Iteration 4

Use TDD to update your Dock class with the following methods:

return - This method takes a Boat object as an argument. When this method is called, it signifies that a boat has been returned and is no longer being rented.
log_hour - This method takes no arguments. When it is called, all boats that are currently rented have been rented an additional hour.
revenue - This method takes no arguments. It returns the total revenue generated by charging all boats that have been rented and returned. A charge for a boat follows the same rules as iteration 3.

The Dock class should now respond to the following interaction pattern:

pry(main)> require './lib/renter'

pry(main)> require './lib/boat'

pry(main)> require './lib/dock'

pry(main)> dock = Dock.new("The Rowing Dock", 3)

pry(main)> kayak_1 = Boat.new(:kayak, 20)

pry(main)> kayak_2 = Boat.new(:kayak, 20)    

pry(main)> canoe = Boat.new(:canoe, 25)    

pry(main)> sup_1 = Boat.new(:standup_paddle_board, 15)    

pry(main)> sup_2 = Boat.new(:standup_paddle_board, 15)    

pry(main)> patrick = Renter.new("Patrick Star", "4242424242424242")

pry(main)> eugene = Renter.new("Eugene Crabs", "1313131313131313")    

# Rent Boats out to first Renter
pry(main)> dock.rent(kayak_1, patrick)

pry(main)> dock.rent(kayak_2, patrick)

# kayak_1 and kayak_2 are rented an additional hour
pry(main)> dock.log_hour

pry(main)> dock.rent(canoe, patrick)

# kayak_1, kayak_2, and canoe are rented an additional hour
pry(main)> dock.log_hour

# Revenue should not be generated until boats are returned
pry(main)> dock.revenue
# => 0

pry(main)> dock.return(kayak_1)

pry(main)> dock.return(kayak_2)

pry(main)> dock.return(canoe)

# Revenue thus far
pry(main)> dock.revenue
# => 105

# Rent Boats out to a second Renter
pry(main)> dock.rent(sup_1, eugene)

pry(main)> dock.rent(sup_2, eugene)

pry(main)> dock.log_hour

pry(main)> dock.log_hour

pry(main)> dock.log_hour

# Any hours rented past the max rental time don't factor into revenue
pry(main)> dock.log_hour

pry(main)> dock.log_hour

pry(main)> dock.return(sup_1)

pry(main)> dock.return(sup_2)

# Total revenue
pry(main)> dock.revenue
# => 195
