### Question:
DMNIncludeModelsClient extends DMNServiceClient { public void loadItemDefinitionsByNamespace(final String modelName, final String namespace, final Consumer<List<ItemDefinition>> consumer) { clientServicesProxy.loadItemDefinitionsByNamespace(modelName, namespace, callback(consumer)); } @Inject  DMNIncludeModelsClient(final DMNClientServicesProxy clientServicesProxy); void loadModels(final Path path,
                           final Consumer<List<IncludedModel>> listConsumer); void loadNodesFromImports(final List<DMNIncludedModel> includeModels,
                                     final Consumer<List<DMNIncludedNode>> consumer); void loadItemDefinitionsByNamespace(final String modelName,
                                               final String namespace,
                                               final Consumer<List<ItemDefinition>> consumer);  }### Answer:
@Test @SuppressWarnings("unchecked") public void testLoadItemDefinitionsByNamespace() { final String modelName = "model1"; final String namespace = ": client.loadItemDefinitionsByNamespace(modelName, namespace, listConsumerDMNItemDefinitions); verify(service).loadItemDefinitionsByNamespace(eq(modelName), eq(namespace), any(ServiceCallback.class)); }
