Iteration 1

Use TDD to create a Spacecraft and a Person class that respond to the following interaction pattern:

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

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

pry(main)> daedalus = Spacecraft.new({name: 'Daedalus', fuel: 400})
#=> #<Spacecraft:0x00007ff88ea3fc30...>

pry(main)> daedalus.name
#=> 'Daedalus'

pry(main)> daedalus.fuel
#=> 400

pry(main)> kathy = Person.new('Kathy Chan', 10)
#=> #<Person:0x00007ff88ea979a8...>

pry(main)> kathy.name
#=> "Kathy Chan"

pry(main)> kathy.experience
#=> 10

pry(main)> kathy.specialties
#=> []

pry(main) kathy.add_specialty(:astrophysics)

pry(main) kathy.add_specialty(:quantum_mechanics)

pry(main)> kathy.specialties
#=>[:astrophysics, :quantum_mechanics]

Iteration 2

Use TDD to create a Flotilla class that responds to the following interaction pattern. For the recommend_personnel method, the Flotilla should recommend Persons that match that ships requirements. (A person matches the requirements if they have a specialty that matches a requirement and experience equal to or greater than the requirement)

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

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

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

pry(main)> daedalus = Spacecraft.new({name: 'Daedalus', fuel: 400})
#=> #<Spacecraft:0x00007ff88ea3fc30...>

pry(main)> daedalus.requirements
#=> []

pry(main)> daedalus.add_requirement({astrophysics: 6})

pry(main)> daedalus.add_requirement({quantum_mechanics: 3})

pry(main)> daedalus.requirements
#=> [{astrophysics: 6}, {quantum_mechanics: 3}]

pry(main)> seventh_flotilla = Flotilla.new({designation: 'Seventh Flotilla'})
#=> #<Flotilla:0x00007fe593a28728...>

pry(main)> seventh_flotilla.name
#=> 'Seventh Flotilla'

pry(main)> seventh_flotilla.personnel
#=> []

pry(main)> seventh_flotilla.ships
#=> []

pry(main)> kathy = Person.new('Kathy Chan', 10)
#=> #<Person:0x00007ff88ea979a8...>

pry(main)> kathy.add_specialty(:quantum_mechanics)

pry(main)> polly = Person.new('Polly Parker', 8)
#=> #<Person:0x00007ff88ea374f9...>

pry(main)> polly.add_specialty(:operations)

pry(main)> polly.add_specialty(:maintenance)

pry(main)> rover = Person.new('Rover Henriette', 1)
#=> #<Person:0x00007fe59506ede8...>

pry(main)> rover.add_specialty(:operations)

pry(main)> rover.add_specialty(:maintenance)

pry(main)> sampson = Person.new('Sampson Edwards', 7)
#=> #<Person:0x000013b59506e2e8...>

pry(main)> sampson.add_specialty(:astrophysics)

pry(main)> sampson.add_specialty(:quantum_mechanics)

pry(main)> seventh_flotilla.add_personnel(kathy)

pry(main)> seventh_flotilla.recommend_personnel(daedalus)
#=> [#<Person:0x00007ff88ea979a8...>, #<Person:0x000013b59506e2e8...]

pry(main)> odyssey = Spacecraft.new({name: 'Odyssey', fuel: 300})
#=> #<Spacecraft:0x00007ff88ea3fc30...>

pry(main)> odyssey.add_requirement({operations: 6})

pry(main)> odyssey.add_requirement({maintenance: 3})

pry(main)> seventh_flotilla.recommend_personnel(odyssey)
#=> [#<Person:0x00007ff88ea374f9...>]

Iteration 3

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

Notes:

For personnel_by_ship this method takes no arguments and returns a hash where the keys are ships and the values are an array of personnel that are qualified to be on said ship.
