/**
 * {@code TestExecutionListener} defines a <em>listener</em> API for reacting to
 * test execution events published by the {@link TestContextManager} with which
 * the listener is registered.
 * <p>Concrete implementations must provide a {@code public} no-args constructor,
 * so that listeners can be instantiated transparently by tools and configuration
 * mechanisms.
 * <p>Implementations may optionally declare the position in which they should
 * be ordered among the chain of default listeners via the
 * {@link org.springframework.core.Ordered Order} interface or
 * {@link org.springframework.core.annotation.Order @Order} annotation. See
 * {@link TestContextBootstrapper#getTestExecutionListeners()} for details.
 * <p>Spring provides the following out-of-the-box implementations (all of
 * which are annotated with {@code @Order}):
 * <ul>
 * <li>{@link org.springframework.test.context.web.ServletTestExecutionListener
 * ServletTestExecutionListener}</li>
 * <li>{@link org.springframework.test.context.support.DependencyInjectionTestExecutionListener
 * DependencyInjectionTestExecutionListener}</li>
 * <li>{@link org.springframework.test.context.support.DirtiesContextTestExecutionListener
 * DirtiesContextTestExecutionListener}</li>
 * <li>{@link org.springframework.test.context.transaction.TransactionalTestExecutionListener
 * TransactionalTestExecutionListener}</li>
 * <li>{@link org.springframework.test.context.jdbc.SqlScriptsTestExecutionListener
 * SqlScriptsTestExecutionListener}</li>
 * </ul>
