This assignment will make you familiar with unit testing, and with object-oriented programming in Python.
Your assignment solution should clearly present:
Upload all source and result files to WebCT and provide links to all of them from your index.html file.

You must come up with a reasonable (don't go overboard !) list of tests (mention their type!) to check the correct implementation of the above classes/methods. Note that you will have to define the requirements yourself based on the comment given in the classes above.
Note that you will need to do type checking of method arguments as Python does not do static type checking.
These test should be implemented in a file testsuite.py using the PyUnit testing framework.
