Example 1 with Result

use of com.vaadin.flow.data.binder.Result in project linkki by linkki-framework.

the class BindLabelValueAspectDefinitionTest method testCreateComponentValueSetter_UsesCustomConverter.

@Test
void testCreateComponentValueSetter_UsesCustomConverter() {
    LinkkiText label = new LinkkiText();
    Consumer<Object> valueSetter = new BindLabelValueAspectDefinition().createComponentValueSetter(new NoLabelComponentWrapper(label));
    LinkkiConverterRegistry converterRegistry = LinkkiConverterRegistry.DEFAULT.with(new Converter<String, FooBar>() {

        private static final long serialVersionUID = 1L;

        @Override
        public Result<FooBar> convertToModel(String value, ValueContext context) {
            return Result.ok(FooBar.valueOf(value));
        }

        @Override
        public String convertToPresentation(FooBar value, ValueContext context) {
            return value == FooBar.FOO ? "Foo" : "Bar";
        }
    });
    VaadinSession vaadinSession = mock(VaadinSession.class);
    when(vaadinSession.getAttribute(LinkkiConverterRegistry.class)).thenReturn(converterRegistry);
    VaadinSession.setCurrent(vaadinSession);
    valueSetter.accept(FooBar.FOO);
    assertThat(label.getText(), is("Foo"));
}
