### Question:
ItemFacade implements Item { @Override public final boolean isNode() { return delegate.isNode(); } @SuppressWarnings("WeakerAccess")  ItemFacade(final @NotNull J delegate, final @NotNull SessionFacade<S> session); @SuppressWarnings("WeakerAccess") static @NotNull Item ensureBestWrapper(final @NotNull Item primaryItem, final @NotNull SessionFacade<?> session); @Override final String getPath(); @Override final String getName(); @Override final Item getAncestor(int depth); @Override final Node getParent(); @Override final int getDepth(); @Override final Session getSession(); @Override final boolean isNode(); @Override final boolean isNew(); @Override final boolean isModified(); @Override final boolean isSame(Item otherItem); @Override final void accept(ItemVisitor visitor); @Override final void refresh(boolean keepChanges); @Override final void save(); @Override final void remove();  }### Answer:
@Test public void testIsNode() throws Exception { Item delegate = mock(Item.class); ItemFacade<Item, Session> facade = getFacade(delegate); when(delegate.isNode()).thenReturn(true); assertTrue("is true", facade.isNode()); }
