### Question:
BaseProvider { protected static boolean isPropertyRequested(String propertyId, Set<String> requestedIds) { return requestedIds.contains(propertyId) || isPropertyCategoryRequested(propertyId, requestedIds) || isPropertyEntryRequested(propertyId, requestedIds); } BaseProvider(Set<String> propertyIds); Set<String> checkPropertyIds(Set<String> propertyIds); Set<String> getPropertyIds(); Set<String> getCategoryIds();  }### Answer:
@Test public void testIsPropertyRequested() { Set<String> propertyIds = new HashSet<>(); propertyIds.add("p1"); propertyIds.add("foo"); propertyIds.add("cat1/foo"); propertyIds.add("cat2/bar"); propertyIds.add("cat2/baz"); propertyIds.add("cat3/sub1/bam"); propertyIds.add("cat4/sub2/sub3/bat"); propertyIds.add("cat5/sub5"); assertTrue(BaseProvider.isPropertyRequested("foo", propertyIds)); assertTrue(BaseProvider.isPropertyRequested("cat2", propertyIds)); assertTrue(BaseProvider.isPropertyRequested("cat2/bar", propertyIds)); assertFalse(BaseProvider.isPropertyRequested("unsupported", propertyIds)); assertTrue(BaseProvider.isPropertyRequested("cat5/sub5/prop5", propertyIds)); assertTrue(BaseProvider.isPropertyRequested("cat5/sub5/sub5a/prop5a", propertyIds)); assertFalse(BaseProvider.isPropertyRequested("cat5/sub7/unsupported", propertyIds)); }
