In many cases when we write tests we create dummy data for the test. E.g., new Person("Ittay Dror", 37) . The problem is that while the test may pass for this data, we can't be sure it works for any data (what happens if a person's age is 0 (a newborn)?). This is worse if the tested code involves algorithms, which in many cases have corner cases that we may not be aware of.
QuickCheck provides utility methods to generate values for our test. Then we simply embed the test inside a foreach loop of these values.
