TDD-AnimalFactory

this is a pretty big lab. important to get it done.

remember, make your last commit message "finished" after you have figured it all out

• Objective:
  • To create tests that ensure expected behavior of each class:
    • Cat
    • Dog
    • AnimalFactory
    • CatHouse
    • DogHouse
• Purpose:
  • To establish familiarity with Test-Driven-Development (TDD) practices.
• Getting context:

Getting Started

• You probably already have IntelliJ installed, right?
• Begin by opening the project via its pom.xml with IntelliJ.
  • How do I install IntelliJ?
• Continue by opening the test.java.rocks.zipcodewilmington package and completing each of the TODOs.

CatTest

• Create tests for void setName(String name)
  • ensure that when .setName is invoked on an instance of Cat, the name field is being set to the respective value.
• Create tests for setBirthDate(Date birthDate)
  • ensure that when .setBirthDate is invoked on an instance of Cat, the birthDate field is being set to the respective value.
• Create tests for String speak()
  • ensure that when .speak is invoked on an instance of Cat, the value "meow!" is returned.
• Create tests for void eat(Food food)
  • ensure that when .eat is invoked on an instance of Cat, the numberOfMealsEaten is increased by 1.
• Create tests for Integer getId()
  • ensure that when .getId is invoked on an instance of Cat, the respective id value is returned.
• Create test to check Animal inheritance; google search java instanceof keyword
  • ensure that a Cat is an instanceof an Animal
• Create test to check Mammal inheritance; google search java instanceof keyword
  • ensure that a Cat is an instanceof a Mammal

DogTest

• Create tests for void setName(String name)
  • ensure that when .setName is invoked on an instance of Dog, the name field is being set to the respective value.
• Create tests for setBirthDate(Date birthDate)
  • ensure that when .setBirthDate is invoked on an instance of Dog, the birthDate field is being set to the respective value.
• Create tests for String speak()
  • ensure that when .speak is invoked on an instance of Dog, the value "bark!" is returned.
• Create tests for void eat(Food food)
  • ensure that when .eat is invoked on an instance of Dog, the numberOfMealsEaten is increased by 1.
• Create tests for Integer getId()
  • ensure that when .getId is invoked on an instance of Dog, the respective id value is returned.
• Create test to check Animal inheritance; google search java instanceof keyword
  • ensure that a Dog is an instanceof an Animal
• Create test to check Mammal inheritance; google search java instanceof keyword
  • ensure that a Dog is an instanceof an Mammal

AnimalFactoryTest

• Create Test for Animal createDog(String name, Date birthDate)
  • ensure that when .createDog is invoked on AnimalFactoryTest a Dog is created with the respective name and birthDate value.
• Create Test for Animal createCat(String name, Date birthDate)
  • ensure that when .createCat is invoked on AnimalFactoryTest a Dog is created with the respective name and birthDate value.

CatHouseTest

• Create tests for void add(Cat cat)
  • ensure that when .add is invoked on the CatHouse, a respective Cat object can be retrieved from the house.
• Create tests for void remove(Cat cat)
  • ensure that when .remove is invoked on the CatHouse, a respective Cat object can no longer be retrieved from the house.
• Create tests for void remove(Integer id)
  • ensure that when .remove is invoked on the CatHouse, a Cat object with the respective id can no longer be retrieved from the house.
• Create tests for Cat getCatById(Integer id)
  • ensure that when .getCatById is invoked on the CatHouse, a Cat with the respective id is returned.
• Create tests for Integer getNumberOfCats()
  • ensure that when .getNumberOfCats() is invoked on the CatHouse, the respective number of Cat objects is returned.

DogHouseTest

• Create tests for void add(Dog dog)
  • ensure that when .add is invoked on the DogHouse, a respective Dog object can be retrieved from the house.
• Create tests for void remove(Integer id)
  • ensure that when .remove is invoked on the DogHouse, a respective Dog object can no longer be retrieved from the house.
• Create tests for void remove(Dog dog)
  • ensure that when .remove is invoked on the DogHouse, a Dog object with the respective id can no longer be retrieved from the house.

Now...

Why is this lab important?

Java Inheritance

Java inheritance makes things easier for a programmer by allowing them to reuse code and create more flexible and modular programs. Inheritance allows a subclass to inherit properties and methods from a superclass, which can save time and effort when writing code.

By using inheritance, programmers can create a hierarchy of classes that share common properties and behaviors. This can make the code easier to understand and maintain, as changes made to the superclass will automatically be inherited by the subclasses. In addition, inheritance can help to reduce code duplication, as common properties and behaviors can be defined in the superclass and reused by the subclasses.

Inheritance also allows for polymorphism, which is the ability of objects to take on multiple forms. This means that a subclass can be treated as an instance of its superclass, which can make the code more flexible and adaptable to changing requirements. For example, a program that uses inheritance can easily add new subclasses without having to modify the existing code.
