/**
 * Annotation that can be used in combination with {@code @RunWith(SpringRunner.class)}
 * for a typical Spring MVC test. Can be used when a test focuses <strong>only</strong> on
 * Spring MVC components.
 * <p>
 * Using this annotation will disable full auto-configuration and instead apply only
 * configuration relevant to MVC tests (i.e. {@code @Controller},
 * {@code @ControllerAdvice}, {@code @JsonComponent} {@code Filter},
 * {@code WebMvcConfigurer} and {@code HandlerMethodArgumentResolver} beans but not
 * {@code @Component}, {@code @Service} or {@code @Repository} beans).
 * <p>
 * By default, tests annotated with {@code @WebMvcTest} will also auto-configure Spring
 * Security and {@link MockMvc} (include support for HtmlUnit WebClient and Selenium
 * WebDriver). For more fine-grained control of MockMVC the
 * {@link AutoConfigureMockMvc @AutoConfigureMockMvc} annotation can be used.
 * <p>
 * Typically {@code @WebMvcTest} is used in combination with {@link MockBean @MockBean} or
 * {@link Import @Import} to create any collaborators required by your {@code @Controller}
 * beans.
 * <p>
 * If you are looking to load your full application configuration and use MockMVC, you
 * should consider {@link SpringBootTest @SpringBootTest} combined with
 * {@link AutoConfigureMockMvc @AutoConfigureMockMvc} rather than this annotation.
