Functions to be tested

Hereafter, for each classes give function to be tested. Remember that all functions does not have to be tested, some code can be checked by a simple inspection or an analyse, another code can be validated by definition (rules, etc) the others function can be tecsted by unit tests, integration tests or validation tests (IADT: Inspect, Analyse, Define, Test).

Classe Machine

functions

Classe Reflector

functions

Classe Rotor

functions

Tricks & tips

• Start with simple classes (models, libraries, etc) at the end make test into complex classes (classes with multiple relations)
• 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)
