ChaincodeRepositoryConfigurationExtension extends RepositoryConfigurationExtensionSupport { @Override protected Collection<Class<?>> getIdentifyingTypes() { logger.debug("getIdentifyingTypes return {" + ChaincodeRepository.class.getName() + "}"); return Collections.singleton(ChaincodeRepository.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 getIdentifyingTypes() { Assert.assertTrue("Not contain correct base class", extension.getIdentifyingTypes().contains(ChaincodeRepository.class)); }
