### Question:
ChronicleMapProxy implements MapProxy<CharSequence, ItemSource> { @NotNull @Override public Collection<ItemSource> values() { return chronicleMap.values(); } ChronicleMapProxy(ChronicleMap<CharSequence, ItemSource> chronicleMap); @Override ItemSource put(CharSequence key, ItemSource failedItem); @Override ItemSource remove(Object key); @Override void putAll(@NotNull Map<? extends CharSequence, ? extends ItemSource> map); @Override boolean containsKey(Object key); @Override ItemSource get(Object key); @Override void clear(); @NotNull @Override Set<CharSequence> keySet(); @NotNull @Override Collection<ItemSource> values(); @NotNull @Override Set<Entry<CharSequence, ItemSource>> entrySet(); @Override int size(); @Override boolean isEmpty(); @Override boolean containsValue(Object value); @Override void close();  }### Answer:
@SuppressWarnings("ResultOfMethodCallIgnored") @Test public void valuesDelegates() { ChronicleMap<CharSequence, ItemSource> chronicleMap = createDefaultTestChronicleMap(); ChronicleMapProxy proxy = createDefaultTestProxy(chronicleMap); proxy.values(); Mockito.verify(chronicleMap).values(); }
