### Question:
DMNDomainValidatorImpl implements DMNDomainValidator { @Override public String getDefinitionSetId() { return BindableAdapterUtils.getDefinitionSetId(DMNDefinitionSet.class); } @Inject  DMNDomainValidatorImpl(final DMNMarshallerStandalone dmnMarshaller,
                                  final DMNDiagramUtils dmnDiagramUtils,
                                  final DMNMarshallerImportsHelperStandalone importsHelper,
                                  final DMNIOHelper dmnIOHelper); @PostConstruct void setupValidator(); @Override String getDefinitionSetId(); @Override @SuppressWarnings("unchecked") void validate(final Diagram diagram,
                         final Consumer<Collection<DomainViolation>> resultConsumer); @Override Collection<DomainViolation> validate(final Diagram diagram,
                                                final String diagramXml);  }### Answer:
@Test public void testGetDefinitionSetId() { assertThat(domainValidator.getDefinitionSetId()).isEqualTo(DMNDefinitionSet.class.getName()); }
