概述：
我对Elastic搜索测试完全陌生，我将添加适当的单元测试。项目兼容性如下：
有关ES配置的更多信息如下：

问题：
如果不在计算机上运行独立的ES，我不知道如何模拟ES或如何测试ES。请使用以下类作为示例，让我知道如何为getSearchResponse方法编写一个测试用例（单元测试不集成）：
import java.util.Arrays;
import java.util.List;
import java.util.Map;
import java.util.stream.Collectors;
import org.elasticsearch.action.search.SearchRequest;
import org.elasticsearch.action.search.SearchResponse;
import org.elasticsearch.client.transport.NoNodeAvailableException;
import org.elasticsearch.client.transport.TransportClient;
import org.elasticsearch.script.ScriptType;
import org.elasticsearch.script.mustache.SearchTemplateRequestBuilder;
import org.elasticsearch.search.Scroll;
import org.elasticsearch.search.aggregations.Aggregation;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.beans.factory.annotation.Value;
import org.springframework.context.MessageSource;
import org.springframework.stereotype.Repository;
@Slf4j
@Repository
@NoArgsConstructor
public abstract class NewBaseElasticsearchRepository {
@Autowired
protected NewIndexLocator newIndexLocator;
@Value(value = "${elasticsearch.client.timeout}")
private Long timeout;
@Autowired
protected TransportClient transportClient;
@Autowired
protected ThresholdService thresholdService;
@Autowired
protected MessageSource messageSource;
/**
* @param script the name of the script to be executed
* @param templateParams a map of the parameters to be sent to the script
* @param indexName the index to target (an empty indexName will search all indexes)
*
* @return a Search Response object containing details of the request results from Elasticsearch
*
* @throws NoNodeAvailableException thrown when the transport client cannot connect to any ES Nodes (or Coordinators)
* @throws Exception thrown for all other request errors such as parsing and non-connectivity related issues
*/
protected SearchResponse getSearchResponse(String script, Map<String, Object> templateParams, String... indexName) {
log.debug("transport client >> index name --> {}", Arrays.toString(indexName));
SearchResponse searchResponse;
try {
searchResponse = new SearchTemplateRequestBuilder(transportClient)
.setScript(script)
.setScriptType(ScriptType.STORED)
.setScriptParams(templateParams)
.setRequest(new SearchRequest(indexName))
.execute()
.actionGet(timeout)
.getResponse();
} catch (NoNodeAvailableException e) {
log.error(ELASTIC_SEARCH_EXCEPTION_NOT_FOUND, e.getMessage());
throw new ElasticSearchException(ELASTIC_SEARCH_EXCEPTION_NOT_FOUND);
} catch (Exception e) {
log.error(ELASTIC_SEARCH_EXCEPTION, e.getMessage());
throw new ElasticSearchException(ELASTIC_SEARCH_EXCEPTION);
}
log.debug("searchResponse ==> {}", searchResponse);
return searchResponse;
}
因此，如果您能看一下示例类，并在这里与我分享您的真实解决方案，以了解如何模拟TransportClient并从{{1}得到正确的答复，我将不胜感激。 }对象。
注意：
SearchResponse中的ESTestCase，但是遇到了org.elasticsearch.test:framework:6.2.4问题，无法解决。同时，我通常找不到任何与此文档或Java ES单元测试相关的文档。
