They consists of method preconditions and postconditions, of object invariants, and of assertions and loop invariants. Ideally, the programmer will annotate all of her code with contracts which are mechanically checked by some static analysis tool. In practice, programmers only write few contracts, mainly preconditions [&hellip;]"}
