Example 6 with SerializableConsumer

use of com.vaadin.flow.function.SerializableConsumer in project flow by vaadin.

the class ShortcutRegistrationTest method listenOnUIIsClosing_eventIsPopulatedForANewUI.

@Test
public void listenOnUIIsClosing_eventIsPopulatedForANewUI() {
    UI ui = Mockito.spy(UI.class);
    Component owner = new FakeComponent();
    Component[] components = new Component[] { ui };
    ui.add(owner);
    new ShortcutRegistration(owner, () -> components, event -> {
    }, Key.KEY_A);
    UI newUI = Mockito.spy(UI.class);
    // close the previous UI
    ui.close();
    components[0] = newUI;
    owner.getElement().removeFromTree();
    newUI.add(owner);
    ArgumentCaptor<SerializableConsumer> captor = ArgumentCaptor.forClass(SerializableConsumer.class);
    verify(ui, atLeastOnce()).beforeClientResponse(eq(owner), captor.capture());
    SerializableConsumer consumer = captor.getValue();
    // Fake beforeClientExecution call.
    consumer.accept(mock(ExecutionContext.class));
    // the new UI should now also have expression with KeyA
    Assert.assertTrue(hasKeyAInKeyDownExpression(newUI));
