 * {@code @Order} is an annotation that is used to configure the
 * {@linkplain #value order} in which the annotated element (i.e., field,
 * method, or class) should be evaluated or executed relative to other elements
 * of the same category.
 *
 * When used with
 * {@link org.junit.jupiter.api.extension.RegisterExtension @RegisterExtension} or
 * {@link org.junit.jupiter.api.extension.ExtendWith @ExtendWith},
 * the category applies to extension fields. When used with
 * {@link MethodOrderer.OrderAnnotation}, the category applies to test methods.
 * When used with {@link ClassOrderer.OrderAnnotation}, the category applies to
 * test classes.
 *
 * 
If {@code @Order} is not explicitly declared on an element, the
 * {@link #DEFAULT} order value will be assigned to the element.
