Functions to be tested

Hereafter, for each classes give function to be tested

Classe Machine

functions

advanceRotors
convert
convertChar

Classe Reflector

function

reflectorFactory

Classe Rotor

function

rotorFactory
convertForward
convertBackward
advance

Tricks & tips

• Never test auto generate code
• Never test creator (its a design problem)
• Use @Test before each testFunction !
• When you test a void function of the class Rotor, then test the rotor instance's state

Rotor r=new Rotor(); int actual = r.getosition();

• You can test a function than throws an exception with the argument: expected

@Test(expected=Exception.class)
