Coffee MakerThe tests outlined below are the black box and acceptance test cases for the Coffee Maker Example. The CoffeeMaker is a command line interface application that will server as the software of a Coffee Maker. To run the CoffeeMaker example, run the Main class. The Main class provides the command line interface functionality that is used for testing of the back end software. Later a new class will be written that interfaces with the actual CoffeeMaker hardware, based on the functionality of the Main class.
