Selecting for tests

I selected 3 classes from the project Cyclone and 3 methods of each class. I hope isn't extremely difficult to understand and create the unit tests, I wasn't very good on physics so I hope I can manage it. The code doesn't look very simple, another problem is that I haven't ever code in C++ so is not my language of expertise hopefully I will  deliver a good homework. We had fun in our meetings setting up the environment, rules, agenda etc.
