ChaincodeRepositoryConfigurationExtension extends RepositoryConfigurationExtensionSupport { @Override protected Collection<Class<? extends Annotation>> getIdentifyingAnnotations() { logger.debug("getIdentifyingAnnotations return {" + Chaincode.class.getName() + "}"); return Collections.singleton(Chaincode.class); }  @Override String getModuleName(); @Override String getRepositoryFactoryBeanClassName(); @Override Collection<RepositoryConfiguration<T>> getRepositoryConfigurations(
            T configSource, ResourceLoader loader, boolean strictMatchesOnly); @Override void postProcess(BeanDefinitionBuilder builder, AnnotationRepositoryConfigurationSource config);  }### Answer:
@Test public void getIdentifyingAnnotations() { Assert.assertTrue("Not contain correct annotation", extension.getIdentifyingAnnotations().contains(Chaincode.class)); }
