/**
 * When a class is annotated with @RunWith or extends a class annotated
 * with @RunWith, JUnit will invoke the class it references to run the
 * tests in that class instead of the runner built into JUnit. We added this feature late
 * in development. While it seems powerful we expect the runner API to change as we learn
 * how people really use it. Some of the classes that are currently internal will likely
 * be refined and become public.
 *
 * For example, suites in JUnit 4 are built using RunWith, and a custom runner named Suite:
 *
 *  * @RunWith(Suite.class)
 * @SuiteClasses({ATest.class, BTest.class, CTest.class})
 * public class ABCSuite {
 * }
 * 
 *
 * @since 4.0
