Ol' McFroilan Had a Farm

• Objective: To implement a system representative of a Farm environment
• Purpose: To demonstrate multi-inheritence design issues
• Prerequesites: A UML approved by an instructor.

Setting the Plot...

• Consider a system in which

  • Eater can eat an Edible object.

  • NoiseMaker can makeNoise

  • Animal is a NoiseMaker and Eater

    • Horse is an Animal and Rideable
    • Chicken is an Animal and a Produce which yield an EdibleEgg if hasBeenFertilized flag is false.

  • Rider can mount and dismount a Rideable object.

  • Botanist can plant a Crop in a CropRow.

  • CropRow can store many Crop.

  • Field can store many CropRow

  • Vehicle are NoiseMaker and Rideable

    • FarmVehicle can operate on a Farm

      • Tractor is a FarmVehicle which can harvest a Crop.

    • Aircraft are Vehicle which can fly

      • CropDuster is a FarmVehicle and Aircraft which can fertilize a CropRow

  • Produce can yield an Edible object depending on their hasBeenFertilized flag.

    • Crop is a Produce which can yield an Edible object depending on its hasBeenHarvested and hasBeenFertilized flag.
      • CornStalk is a Crop which can yield a EarCorn
      • TomatoPlant is a Crop which can yield a Tomato

  • Person can makeNoise and can eat an Edible object.

  • Farmer is an Eater, a Rider, a Botanist, and a Person.

  • Stable stores many Horse.

  • FarmHouse stores many Person

  • ChickenCoop stores many Chicken

  • Farm stores many Stable, many ChickenCoop, and a single FarmHouse

Establishing The Plot

• Froilan, a Farmer has a Farm consisting of

  • 1 Field of 5 CropRow.

    • Row 1 has Corn
    • Row 2 has Tomato
    • Row 3 and beyond grows arbitrary vegetation.

  • 15 Chicken across 4 ChickenCoop

  • 10 Horse across 3 Stable.

  • 2 FarmVehicle

  • 1 Aircraft

  • His sister, Froilanda, is a Pilot who uses a CropDuster.

The Plot Thickens Chickens...

• Create test cases which simulate a typical work-week for Froilan and Froilanda.

  • The accumulation of your test cases should ensure at least 80% test coverage.

• The first few weekdays have already been considered for you.

• Create a separate Test class for each day in the following scenario.

  • As a farmer, Froilan must stick to a rigorous agricultural routine.

    • Every morning, Froilan and Froilanda begin their morning by

      • Riding each Horse in each Stable.
      • Feeding each Horse 3 ear of Corn.
      • For breakfast,
        • Froilan eats 1 EarCorn, 2 Tomoato, and 5 Egg.
        • Froilanda eats 2 EarCorn, 1 Tomoato, and 2 Egg.

    • Sunday, Froilan plants 3 different type of Crop in his first, second, and third CropRow.

    • On Monday, his sister, Froilanda uses the CropDuster to fly over the Field and fertilize each of the CropRow

    • On Tuesday, Froilan uses his Tractor to harvest each Crop in each CropRow.
