Lab 4 - Burger Multiple Toppings

In the last lab, we moved the responsibility for the pricing of a topping to the BurgerToppings enum. In this lab, you will allow the burger to have multiple toppings.

Make sure ALL tests PASS before you start

1. Write a test for adding a topping to a "core" burger, something like the following:

   Burger burger = new Burger();
   burger.addTopping(BurgerToppings.CHEESE);
   assertThat(burger.price()).isEqualTo(6);
   

   Make sure this test FAILS

2. What Java collection class would be appropriate to keep track of the multiple toppings: Map? Set? List? Why?

   • Remember generics: you will have a collection of BurgerToppings instead of just a single one.

3. Make the test PASS.

4. Write a few more tests and make sure that you cover:

   • Adding no toppings: 5
   • Adding single topping of cheese: 6
   • Adding single cheese and single bacon: 7
   • Adding 2 (two) cheese toppings: 7

   Make sure ALL tests pass

5. Increase price of Bacon to 2

   • Modify your test first
   • Then make the change to make the test pass

You are done when ALL tests pass.
