Unit testing

Finish the implementation of the Pizza Ordering System from yesterday including the extra challenges.

Now … does the code work properly? Have you tested it?

Write tests to verify that the system works as intended:

• the expected pizza objects are created with the Factory?
• and decorated with expected toppings?
• the delivery strategy works (including surcharge for express delivery)?
• and total price is calculated as expected with/without discount coupons?

Use:

1. Normal Java class with a main method that can test the above scenarios. OR
2. Use JUnit5 which is a framework made specifically for test of Java methods.
