}

Example 3 with TemplateElementStateProvider

use of com.vaadin.flow.dom.impl.TemplateElementStateProvider in project flow by vaadin.

the class TemplateElementStateProviderTest method requiredNodeFeatures.

@Test
@SuppressWarnings("unchecked")
public void requiredNodeFeatures() {
    Class<? extends NodeFeature>[] requiredFeatures = new Class[] { TemplateOverridesMap.class };
    TemplateElementStateProvider provider = (TemplateElementStateProvider) createElement("<div></div").getStateProvider();
    // Test that a node with all required features is accepted
    Assert.assertTrue(provider.supports(new StateNode(requiredFeatures)));
    // Test that removing any feature makes it non-accepted
    for (int i = 0; i < requiredFeatures.length; i++) {
        List<Class<? extends NodeFeature>> list = new ArrayList<>(Arrays.asList(requiredFeatures));
        list.remove(i);
        Assert.assertFalse(provider.supports(new StateNode(list.toArray(new Class[0]))));
    }
