use of org.kie.dmn.api.marshalling.DMNMarshaller in project drools by kiegroup.

the class DMNXMLLoaderTest method test0004_multiple_extensions.

@Test
public void test0004_multiple_extensions() throws Exception {
    DMNMarshaller marshaller = DMNMarshallerFactory.newMarshallerWithExtensions(Arrays.asList(new DecisionServicesExtensionRegister()));
    final InputStream is = this.getClass().getResourceAsStream("0004-decision-services_multiple_extensions.dmn");
    final InputStreamReader isr = new InputStreamReader(is);
    final Definitions def = marshaller.unmarshal(isr);
    assertThat(def.getExtensionElements().getAny().size(), is(1));
// if arrived here, means it did not fail with exception while trying to unmarshall unknown rss extension element, hence it just skipped it.
}
