    • In this challenge you will update your current Animals project and add unit tests to the project

    Project structure

    Java

    The code you push to git should have the following structure:

    ├── build.gradle
├── gradle
│   └── wrapper
│       ├── gradle-wrapper.jar
│       └── gradle-wrapper.properties
├── gradlew
├── gradlew.bat
├── settings.gradle
└── src
    ├── main
    |   └── java
    |       ├── Animal.java       <-------- names are important
    |       ├── Cat.java          <-------- names are important
    |       ├── Dog.java          <-------- names are important
    |       ├── Home.java         <-------- names are important
    |       └── MainProgram.java  <-------- names are important
    └── test
        └── java
            ├── CatTest.java   <-------- names are important
            └── DogTest.java   <-------- names are important
            ... other logical things

    Instructions

    You’ll be using JUnit.

    1. Create a class called AnimalTests
    2. Update Animal super class eats() function to return a String, “Food”.
    3. Update Dog class sounds() function to return a String, “Bark”.
    4. Update Cat class sounds() function to return a String, “Meow”.
    // Java

Dog dog = new Dog()

dog.eats()    // -> 'Food'
dog.sounds() // -> 'Barks'

Cat cat = new Cat()

cat.eat()    // -> 'Food'
cat.sounds() // -> 'Meow'

    Now let’s add our first JUnit test to our AnimalTests. The class should have the following methods TestDogSound(), TestDogEats(), TestCatSound() and TestCatEats().Each method should have the @Test tag placed above it. The tests should work as follows.

    // Java

//Dog Tests
Test -> Does dog eat Food should Pass
Test -> Does dog eat food should Fail

//Cat Tests
Cat cat = new Cat();
Test -> Does cat Barkark should Fail
Test -> Does cat Meow should Pass
Test -> Does cat eat meat should Fail
Test -> Does cat eat Food should Pass
Test -> Does cat eat food should Fail

    Up for a Challenge?

    This section is not compulsory. If you do this we’ll think you’re cool.

    Add some functionality to TestDog() and TestCat() so that the tests aren’t case sensitive

    eg:

    Test -> Does dog eat Food -> Pass
Test -> Does dog eat food -> Pass
