Draw a use-case diagram for your use cases

Write a class that represents a number. It can be set either by giving it a positive integer, or a string representing a Roman Numeral. It should have methods to get the value as integer or Roman Numeral. Write the program using Test-First Programming with JUnit. Keep a list of which tests you write and in what order.

When you are done, write a short description of your thoughts about using TFP. You should turn in a zip file with your source code (including tests) and the short essay. I am looking for how complete your tests are, how simple the code is, how readable (including good names and comments). This is an individual project, not a team project.

You should email me the zip file.
