### Question:
RenderKitFactoryWrapper extends RenderKitFactory implements FacesWrapper<RenderKitFactory> { @Override public Iterator<String> getRenderKitIds() { return getWrapped().getRenderKitIds(); }  @Override abstract RenderKitFactory getWrapped(); @Override void addRenderKit(String renderKitId, RenderKit renderKit); @Override RenderKit getRenderKit(FacesContext context, String renderKitId); @Override Iterator<String> getRenderKitIds();  }### Answer:
@Test public void shouldWrapGetRenderKitIds() { this.wrapper.getRenderKitIds(); verify(this.wrapped).getRenderKitIds(); }
