Example 1 with UntypedAnnotationDescriptor

use of cn.taketoday.test.context.TestContextAnnotationUtils.UntypedAnnotationDescriptor in project today-framework by TAKETODAY.

the class ContextLoaderUtils method resolveContextHierarchyAttributes.

/**
 * Resolve the list of lists of {@linkplain ContextConfigurationAttributes context
 * configuration attributes} for the supplied {@linkplain Class test class} and its
 * superclasses, taking into account context hierarchies declared via
 * {@link ContextHierarchy @ContextHierarchy} and
 * {@link ContextConfiguration @ContextConfiguration}.
 * <p>The outer list represents a top-down ordering of context configuration
 * attributes, where each element in the list represents the context configuration
 * declared on a given test class in the class hierarchy. Each nested list
 * contains the context configuration attributes declared either via a single
 * instance of {@code @ContextConfiguration} on the particular class or via
 * multiple instances of {@code @ContextConfiguration} declared within a
 * single {@code @ContextHierarchy} instance on the particular class.
 * Furthermore, each nested list maintains the order in which
 * {@code @ContextConfiguration} instances are declared.
 * <p>Note that the {@link ContextConfiguration#inheritLocations inheritLocations} and
 * {@link ContextConfiguration#inheritInitializers() inheritInitializers} flags of
 * {@link ContextConfiguration @ContextConfiguration} will <strong>not</strong>
 * be taken into consideration. If these flags need to be honored, that must be
 * handled manually when traversing the nested lists returned by this method.
 *
 * @param testClass the class for which to resolve the context hierarchy attributes
 * (must not be {@code null})
 * @return the list of lists of configuration attributes for the specified class;
 * never {@code null}
 * @throws IllegalArgumentException if the supplied class is {@code null}; or if
 * neither {@code @ContextConfiguration} nor {@code @ContextHierarchy} is
 * <em>present</em> on the supplied class
 * @throws IllegalStateException if a test class or composed annotation
 * in the class hierarchy declares both {@code @ContextConfiguration} and
 * {@code @ContextHierarchy} as top-level annotations.
