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