/**
 * Simple unit test to verify the expected functionality of standard JUnit 4.4+
 * testing features.
 * <p>
 * Currently testing: {@link Test @Test} (including expected exceptions and
 * timeouts), {@link BeforeClass @BeforeClass}, {@link Before @Before}, and
 * <em>assumptions.
 * </p>
 * <p>
 * Due to the fact that JUnit does not guarantee a particular ordering of test
 * method execution, the following are currently not tested:
 * {@link org.junit.AfterClass @AfterClass} and {@link org.junit.After @After}.
