/**

 * <em>Spring TestContext Framework with explicit
 * {@link ApplicationContext} testing support in a <strong>TestNG
 * environment.
 * </p>
 * <p>
 * Concrete subclasses:
 * </p>
 * <ul>
 * <li>Typically declare a class-level
 * {@link ContextConfiguration @ContextConfiguration} annotation to configure
 * the {@link ApplicationContext application context}
 * {@link ContextConfiguration#locations() resource locations}.
 * <em>If your test does not need to load an application context, you may choose
 * to omit the {@link ContextConfiguration @ContextConfiguration} declaration
 * and to configure the appropriate
 * {@link org.springframework.test.context.TestExecutionListener TestExecutionListeners}
 * manually.</em>
 * <li>Must have constructors which either implicitly or explicitly delegate to
 * <code>super();.
 * </ul>
