### Question:
FxmlLoader extends FXMLLoader { public void onFailure(final Throwable cause) { this.onFailure.accept(cause); } @Autowired  FxmlLoader(ApplicationContext context); void setOnSuccess(final Consumer<Node> onSuccess); void onSuccess(final Node loadResult); void setOnFailure(final Consumer<Throwable> onFailure); void onFailure(final Throwable cause); @Override boolean equals(Object o); @Override int hashCode();  }### Answer:
@Test public void onFailure() { new FxmlLoader(context).onFailure(null); assertThat(succ).isEqualTo(0); assertThat(fail).isEqualTo(0); fxmlLoader.onFailure(null); assertThat(succ).isEqualTo(0); assertThat(fail).isEqualTo(1); }
