 ==== Auto-configured Spring MVC Tests
 To test whether Spring MVC controllers are working as expected, use the `@WebMvcTest` annotation.
-`@WebMvcTest` auto-configures the Spring MVC infrastructure and limits scanned beans to `@Controller`, `@ControllerAdvice`, `@JsonComponent`, `Converter`, `GenericConverter`, `Filter`, `HandlerInterceptor`, `WebMvcConfigurer`, and `HandlerMethodArgumentResolver`.
+`@WebMvcTest` auto-configures the Spring MVC infrastructure and limits scanned beans to `@Controller`, `@ControllerAdvice`, `@JsonComponent`, `Converter`, `GenericConverter`, `Filter`, `HandlerInterceptor`, `WebMvcConfigurer`, `WebMvcRegistrations`, and `HandlerMethodArgumentResolver`.
 Regular `@Component` and `@ConfigurationProperties` beans are not scanned when the `@WebMvcTest` annotation is used.
 `@EnableConfigurationProperties` can be used to include `@ConfigurationProperties` beans.
