/**
 * {@code @DisplayNameGeneration} is used to declare a custom display name
 * generator for the annotated test class.

 * <p>This annotation is <em>inherited</em> from superclasses and implemented
 * interfaces. It is also inherited from {@linkplain Class#getEnclosingClass()
 * enclosing classes} for {@link Nested @Nested} test classes.
 *
 * <p>As an alternative to {@code @DisplayNameGeneration}, a global
 * {@link DisplayNameGenerator} can be configured for the entire test suite via
 * the {@value DisplayNameGenerator#DEFAULT_GENERATOR_PROPERTY_NAME} configuration parameter. See
 * the User Guide for details. Note, however, that a {@code @DisplayNameGeneration}
 * declaration always overrides a global {@code DisplayNameGenerator}.
