The tests must cover each kind of coins (NICKEL, DIME, QUARTER, DOLLAR), each kind of drinks (COFFEE, JUICE, SODA) and each event (Insert Coin, Return Coins, and Purchase). You may run VendingMain.java to get familiar with the GUI. You should not modify the given source code unless absolutely required.
Submit the following artifacts: (a) the source code of the entire VendingMachine project including your test code so that the grader can run your code, (b) an explanation about how your tests have met the above requirements. In case you have modified the source code, provide a justification why your modification is required. (c) a video clip that shows the execution of your test code and execution results. To receive the credit, your test code must be executable without error.
