/**

 * <p>{@code @Rule}-annotated fields as well as methods are supported.
 *
 * <p>By using this class-level extension on a test class such
 * {@code ExternalResource} implementations in legacy code bases
 * can be left unchanged including the JUnit 4 rule import statements.
 *
 * <p>However, if you intend to develop a <em>new</em> extension for
 * JUnit 5 please use the new extension model of JUnit Jupiter instead
 * of the rule-based model of JUnit 4.
