### Question:
ConfigurableNavigationHandlerWrapper extends ConfigurableNavigationHandler implements
		FacesWrapper<ConfigurableNavigationHandler> { @Override public void performNavigation(String outcome) { getWrapped().performNavigation(outcome); }  abstract ConfigurableNavigationHandler getWrapped(); @Override NavigationCase getNavigationCase(FacesContext context, String fromAction, String outcome); @Override Map<String, Set<NavigationCase>> getNavigationCases(); @Override void performNavigation(String outcome); @Override void handleNavigation(FacesContext context, String fromAction, String outcome);  }### Answer:
@Test public void shouldWrapPerformNavigation() throws Exception { this.wrapper.performNavigation(this.outcome); verify(this.wrapped).performNavigation(this.outcome); }
