/**
 * {@code @EnabledOnOs} is used to signal that the annotated test class or
 * test method is only enabled on one or more specified
 * {@linkplain #value operating systems}.
 *
 * When applied at the class level, all test methods within that class
 * will be enabled on the same specified operating systems.
 *
 * 
If a test method is disabled via this annotation, that does not prevent
 * the test class from being instantiated. Rather, it prevents the execution of
 * the test method and method-level lifecycle callbacks such as {@code @BeforeEach}
 * methods, {@code @AfterEach} methods, and corresponding extension APIs.
 *
 * 
This annotation may be used as a meta-annotation in order to create a
 * custom composed annotation that inherits the semantics of this
 * annotation.
 *
 * 
Warning
 *
 * As of JUnit Jupiter 5.1, this annotation can only be declared once on an
 * {@link java.lang.reflect.AnnotatedElement AnnotatedElement} (i.e., test
 * interface, test class, or test method). If this annotation is directly
 * present, indirectly present, or meta-present multiple times on a given
 * element, only the first such annotation discovered by JUnit will be used;
 * any additional declarations will be silently ignored. Note, however, that
 * this annotation may be used in conjunction with other {@code @Enabled*} or
 * {@code @Disabled*} annotations in this package.
