Makers Academy week 3 test - Object oriented model of airports and planes

Airport

Makers Academy Week 3 - Test

This test was set by Enrique Comba Riepenhausen @ecomba and Alex Peattie @alexpeattie whilst learning to code at Makers Academy. The aim was to build an object oriented model of airports and planes in Ruby.

I wrote this code alone using RSpec for TDD. I started by writing the CRC cards (shown below). The primary aim of this test was to write clean, simple, readable code. I think the closest I came to this aim was in my Airport class:

def clear_to_land?
has_space_in_hanger? and has_sunny_weather_and_no_bomb_scare?
end

After the test specification I completed the first stretch goal to give each airport a runway and for planes to taxi to the runway before take off.

This model could be improved by making the airport's collection of planes into a separate Hanger class.

Class Weather

Responsibilities	Collaborators
can be sunny or stormy	Airport
can switch state at random

Class Plane

Responsibilities	Collaborators
can land at an Airport, if clear to land	Airport
can take off from an Airport, if clear to take off

Class Airport

Responsibilities	Collaborators
has a maximum capacity of Planes	Plane
has a collection of Planes	Weather
has its own Weather
can have a bomb scare
can call off a bomb scare
can be clear for take offs and landings
(i.e. has space, not stormy, no bomb scare)
