Example 6 with DependencyFilter

use of com.vaadin.flow.server.DependencyFilter in project flow by vaadin.

the class DefaultTemplateParserTest method defaultParser_useDependencyFilters_returnBundle.

@Test

    AtomicInteger calls = new AtomicInteger();
    DependencyFilter filter = (list, context) -> {
        list.clear();
        list.add(new Dependency(Type.HTML_IMPORT, "/bundle.html", LoadMode.EAGER));
        calls.incrementAndGet();
        return list;
    };
    Mockito.when(service.getDependencyFilters()).thenReturn(Collections.singletonList(filter));
    TemplateParser parser = DefaultTemplateParser.getInstance();
    Element element = parser.getTemplateContent(ImportsInspectTemplate.class, "foo").getTemplateElement();
    Assert.assertTrue(element.getElementById("foo") != null);
    element = parser.getTemplateContent(RootImportsInspectTemplate.class, "foo").getTemplateElement();
    Assert.assertTrue(element.getElementById("foo") != null);
    element = parser.getTemplateContent(OtherImportsInspectTemplate.class, "bar").getTemplateElement();
    Assert.assertTrue(element.getElementById("bar") != null);
    Assert.assertEquals("The DependencyFilter should be called exactly 3 times", 3, calls.get());

    throw new IllegalStateException(String.format("Couldn't find the " + "definition of the element with tag '%s' " + "in any template file declared using '@%s' annotations.
