In these tests, a Piggy object gets instantiated for each and every test method. Good practice in this case is usually to create a `setup()` method annotated with `@Before`, where you create a Piggy object. This method will get called once before each JUnit test method. This will save you from having duplicate code in each test. If you want to learn more about it, here is the junit documentation page
