Functional Verification of Class Invariants in CleanJava

In Cleanroom-style functional program verification, a program is viewed as a mathematical function from one program state to another, and the program is verified by comparing two functions, the implemented and the expected behaviors of a program. The technique requires a minimal mathematical background and supports forward reasoning, but it doesn't support assertions such as class invariants. However, class invariants are not only a practical programming tool but also play a key role in the correctness proof of a program by specifying conditions and constraints that an object has to satisfy and thus defining valid states of the object.
