Missing code

We are going to rewrite RemApp to fill out to do the “bigger” scenario from the test-driven development notes. I have re-organized the code again a little to help support using the Model-View separation concept based on the Model-View-Controller architecture. You will also write your first JUnit test cases:

• Download the files for the lab and put them into a new project.
• Add a new JUnit test class to the project, consoleKit.TestMenuStack:

o   If you are using NetBeans, check the Test Initializer box when creating the class

o   Declare a MenuStack (the files include a skeleton of the class) variable and two Menu variables. The first will be the “parent” menu of the 2^nd.

o   In an initializer function (annotated by @Before)

• Initialize the MenuStack
• Then initialize the Menu’s using this MenuStack
• When you write MenuStack, you will be pushing the Menu’s onto a stack inside the constructor of the Menu

o   Define a test function (include the @Test annotation) that uses assertEquals() to confirm that the current menu for the MenuStack equals the 2^nd menu initialized

o   Fill in MenuStack so that this test case passes.

• It is recommended that you use an ArrayDeque<Menu> to store the stack of Menu’s. The functions for push, pop and top are addFirst(), removeFirst() and getFirst(). The API documentation is at: https://docs.oracle.com/en/java/javase/11/docs/api/java.base/java/util/Deque.html
• Hint: each missing method can be done in one line, though you might use 2-3 lines for run()

o   Define a second test case checks for returning to the previous menu:

• Create a ReturnFromMenumenu item, initializing it with the name of the first Menu and the MenuStack
• Add this menu item to the 2^ndMenu
• Call the menu item’s execute() function
• Use assertEquals() to confirm the current menu is now the parent menu

o   Fill in the missing elements of MenuStack and ReturnFromMenu to get this case to pass

• Run RemAppto see that the program is now functioning correctly. See below for an additional scenario to check the proper return from a nested menu
• Submit your work – because you want TestMenuStackto be included, it is easiest to zip up the whole project folder so that both src and test folders are included

Grading:

40% TestMenuStack

40% MenuStack

20% ReturnFromMenu
