/**
 * {@code @WebAppConfiguration} is a class-level annotation that is used to
 * declare that the {@code ApplicationContext} loaded for an integration test
 * should be a {@link org.springframework.web.context.WebApplicationContext
 * WebApplicationContext}.
 *
 * <p>The mere presence of {@code @WebAppConfiguration} on a test class ensures
 * that a {@code WebApplicationContext} will be loaded for the test using a default
 * for the path to the root of the web application. To override the default,
 * specify an explicit resource path via the {@link #value} attribute.
 *
 * <p>Note that {@code @WebAppConfiguration} must be used in conjunction with
 * {@link org.springframework.test.context.ContextConfiguration @ContextConfiguration},
 * either within a single test class or within a test class hierarchy.
 *
 * <p>As of Spring Framework 4.0, this annotation may be used as a
 * <em>meta-annotation</em> to create custom <em>composed annotations</em>.
