### Question:
NavigationOutcomeResolverChain implements NavigationOutcomeResolver { public boolean canResolve(FacesContext facesContext, NavigationContext navigationContext) { return findResolver(facesContext, navigationContext) != null; }  boolean canResolve(FacesContext facesContext, NavigationContext navigationContext); NavigationOutcome resolve(FacesContext facesContext, NavigationContext navigationContext); void setResolvers(List<NavigationOutcomeResolver> resolvers); List<NavigationOutcomeResolver> getResolvers();  }### Answer:
@Test public void shouldNotResolveIfNullChain() throws Exception { assertThat(this.chain.canResolve(this.facesContext, this.navigationContext), is(false)); }
