### Question:
StatsClientService extends ElasticsearchClientService { public boolean checkStatisticsRecordExists(StatsRecordType type, Map<String, Object> conditions) { if (!statsConfiguration.enabled()) { return false; } SearchRequestBuilder srb = new SearchRequestBuilder(client); srb.setIndices(type.getSearchIndexName()); srb.setTypes(type.getSearchIndexType()); AndFilterBuilder fb = new AndFilterBuilder(); fb.add(new TermsFilterBuilder(FIELD_TYPE, type.getSearchIndexedValue())); if (conditions != null) { for (String fieldName : conditions.keySet()) { fb.add(new TermsFilterBuilder(fieldName, conditions.get(fieldName))); } } srb.setQuery(new FilteredQueryBuilder(QueryBuilders.matchAllQuery(), fb)); srb.addField("_id"); try { SearchResponse searchResponse = srb.execute().actionGet(); return searchResponse.getHits().getTotalHits() > 0; } catch (org.elasticsearch.indices.IndexMissingException e) { return false; } }  @PostConstruct void init(); @PreDestroy void destroy(); SearchResponse performSearch(
			StatsRecordType type,
			FilterBuilder filterBuilder,
			Integer from,
			Integer size,
			String sort); void writeStatisticsRecord(StatsRecordType type, ElasticsearchException ex, long dateInMillis,
									  QuerySettings querySettings); void writeStatisticsRecord(StatsRecordType type, String responseUuid, SearchResponse resp, long dateInMillis,
									  QuerySettings querySettings); void writeStatisticsRecord(StatsRecordType type, long dateInMillis, Map<String, Object> source); boolean checkStatisticsRecordExists(StatsRecordType type, Map<String, Object> conditions); Properties getSettings(); Properties getTransportSettings(); static final String FIELD_STATUS; static final String FIELD_DATE; static final String FIELD_TYPE; static final String FIELD_HITS_ID; static final String FIELD_RESPONSE_UUID; static final String CONFIG_FILE_TRANSPORT; static final String CONFIG_FILE; }### Answer:
@Test public void checkStatisticsRecordExists() { }
