How to feature test in irb

require './lib/airport'

# --------------------------------------------------- #

# create an airport
# airport capacity is optional, default is set to 30
airport = Airport.new(airport_id, <capcity>)

# --------------------------------------------------- #

# to create a plane
# airport_id is optional (will be nil if not provided)
# plane = Plane.new(plane_id, <airport_id>)

# --------------------------------------------------- #

# create weather object
# weather = Weather.new
# weather are randomly 1/5 chances of it being stormy

# --------------------------------------------------- #

Example Run in irb

$ irb
2.5.0 :001 > require './lib/airport'
 => true
2.5.0 :002 > airport = Airport.new('HEATHROW',50)
 => #<Airport:0x00007fa969010940 @capacity=50, @hanger=[], @id="HEATHROW">
2.5.0 :003 > plane = Plane.new('BA5567')
 => #<Plane:0x00007fa96a08d7c8 @id="BA5567", @airport=nil>
2.5.0 :004 > weather = Weather.new
 => #<Weather:0x00007fa96a0a1480 @stormy=[false, true, false, false, false]>
2.5.0 :005 > airport.land(plane,weather.stormy?)
 => [#<Plane:0x00007fa96a08d7c8 @id="BA5567", @airport="HEATHROW">]
2.5.0 :006 > airport.take_off(plane,weather.stormy?)
 => #<Plane:0x00007fa96a08d7c8 @id="BA5567", @airport=nil>

Classes and methods

Airport class methods

Airport.land(plane, weather)
# allows planes to land
# land() will throw error if
# - Plane has already landed at an(y) airport
# - Weather is stormy (can be overriden by passing false instead of weather)
# - Airport capacity is reached and there is no more space

Airport.take_off(plane, weather)
# allows planes to take_off if Weather_obj.stormy is false
# take_off() will throw error if
# - Plane not at the airport (in mid air or at any other airport)
# - Weather is stormy (can be overriden by passing false instead of weather)

Airport.full?()
# private method full() returns true or false depending on number of planes in the hanger

Plane class methods

# No public methods. Just initialize() method that takes arguments as above

Weather class methods

Weather.stormy?()
# stormy?(). This method returns true or false randomly 1/5 chances of storm
