public class Test002ExtendingRandomizedTest
extends RandomizedTest

To start using pseudo-randomization we need to get hold of the RandomizedContext instance associated with the test. This can be done manually, as shown in getContextByHand() method or (better) we can extend RandomizedTest and have a superclass method to handle this (and more) for us as shown in {#link #getContextFromSuper()}

Note that Random instances acquired from the context are preinitialized with a repeatable seed (we'll get to that) so tests can be re-run with the same random sequence if something fails.
