/**
 * {@link EventListener @EventListener} annotation used to consume a
 * {@link AfterTestClassEvent} published by the
 * {@link org.springframework.test.context.event.EventPublishingTestExecutionListener
 * EventPublishingTestExecutionListener}.
 *
 * <p>This annotation may be used on {@code @EventListener}-compliant methods within
 * a Spring test {@link org.springframework.context.ApplicationContext ApplicationContext}
 * &mdash; for example, on methods in a
 * {@link org.springframework.context.annotation.Configuration @Configuration}
 * class. A method annotated with this annotation will be invoked as part of the
 * {@link org.springframework.test.context.TestExecutionListener#afterTestClass}
 * lifecycle.
 *
 * <p>Event processing can optionally be made {@linkplain #value conditional} via
 * a SpEL expression &mdash; for example,
 * {@code @AfterTestClass("event.testContext.testClass.name matches '.+IntegrationTests'")}.
 *
 * <p>The {@code EventPublishingTestExecutionListener} must be registered in order
 * for this annotation to have an effect &mdash; for example, via
 * {@link org.springframework.test.context.TestExecutionListeners @TestExecutionListeners}.
