Chapter 10 Testing
Contracts preconditions - relationships that must hold before a function is executed, postconditions- relationships that must hold after a function is executed, invariants - relationships that must hold while a function is executed.
Equivalence Classes The equivalence classes we might consider for this code include: even positive numbers odd positive numbers even negative numbers odd negative numbers zero
