### Question:
ElasticsearchDomainMapProvider { private Map<String, String> getDomainMap(List<ElasticsearchDomainStatus> domainStatusList) throws RuntimeException { Map<String, String> domainMap = new HashMap<>(); for (ElasticsearchDomainStatus domainStatus : domainStatusList) { domainMap.put(domainStatus.getDomainName(), endpointPrefix + domainStatus.getEndpoint()); } if (domainMap.isEmpty()) { throw new RuntimeException("Amazon Elasticsearch Service has no domain information for user."); } return domainMap; } protected  ElasticsearchDomainMapProvider(boolean autoDiscoverEndpoint);   }### Answer:
@Test public void getDomainMapTest() { logger.info("getDomainMapTest - enter"); ElasticsearchDomainMapProvider domainMapProvider = new ElasticsearchDomainMapProvider(false); String domainMapping = "domain1=myusername@password:www.endpoint1.com,domain2=myusername@password:www.endpoint2.com"; Map<String, String> domainMap = domainMapProvider.getDomainMap(domainMapping); logger.info("Domain map: {}", domainMap); assertEquals("Invalid number of elements in map:", 2, domainMap.size()); assertEquals("Invalid value for domain1:", "myusername@password:www.endpoint1.com", domainMap.get("domain1")); assertEquals("Invalid value for domain2:", "myusername@password:www.endpoint2.com", domainMap.get("domain2")); logger.info("getDomainMapTest - exit"); }
