/**
* Sometimes several tests need to share computationally expensive setup
* (like logging into a database). While this can compromise the independence of
* tests, sometimes it is a necessary optimization. Annotating a public static void
no-arg method
* with @BeforeClass
causes it to be run once before any of
* the test methods in the class. The @BeforeClass
methods of superclasses
* will be run before those of the current class, unless they are shadowed in the current class.
*
* For example:
*
* public class Example {
* @BeforeClass public static void onlyOnce() {
* ...
* }
* @Test public void one() {
* ...
* }
* @Test public void two() {
* ...
* }
* }
*
*
* @see org.junit.AfterClass
* @since 4.0
