import unittest

# requirements:
# 1. You want to write a GameDie class
# 2. GameDie has a constructor, it expects a desired number of
#    sides, and it produces a game die instance with that many
#    sides
# 3. GameDie includes accessors methods such as getNumSides,
#    which returns the number of sides of that die,
#    getNumRolls, how many times it has been rolled,
#    and getLastRoll, the value of the latest roll
# 4. Its roll method should produce a value between 1 and the
#    number of sides, should have the effect of changing the
#    number of rolls and the last roll values for that die.

#   this is the modiule to import to use PyUnit

import unittest

#   in PyUnit, test cases are represented by the TestCase class in
#   the unittest module

class NumSidesTestCase(unittest.TestCase):
   #   override the runTest method

   def runTest(self):
