### Question:
IOC { public static IKey getKeyForKeyStorage() { return container.getKeyForKeyStorage(); } private  IOC(); static IKey getIocKey(); static IKey getKeyForKeyStorage(); static T resolve(final IKey key, final Object ... args); static void register(final IKey key, final IResolveDependencyStrategy strategy); static void remove(final IKey key);  }### Answer:
@Test public void checkGetKeyForKeyStorage() throws Exception { when(container.getKeyForKeyStorage()).thenReturn(mock(IKey.class)); IKey key = IOC.getKeyForKeyStorage(); assertNotNull(key); }
