sgmarghade/mock-elasticsearch-server

Helps to create mock in memory elasticsearch server for unit testing ur code.

Elasticsearch mock will help you to embed inmemory single node elasticsearch in test cases to mock actual elasticsearch calls and still run end to end application use cases .

#Usage

MockElasticsearchServer server = new MockElasticsearchServer("TmpDataDirectoryPath",<List of indices to be deleted on shutdown>)

// Saving data

 server.getClient()
                .prepareIndex()
                .setIndex(TEST_INDEX)
                .setType(TEST_TYPE)
                .setId("1")
                .setSource(mapper.writeValueAsString(data))
                .execute()
                .get(2, TimeUnit.SECONDS);

server.refresh(TEST_INDEX);

// Getting data
SearchResponse searchResponse = server.getClient()
                .prepareSearch(TEST_INDEX)
                .setTypes(TEST_TYPE)
                .setQuery(
                        QueryBuilders.constantScoreQuery(
                                FilterBuilders.boolFilter()
                                        .must(FilterBuilders.termFilter("key1", "value1"))))
                .setNoFields()
                .setSize(1)
                .execute()
                .actionGet();


// Deleting index
server.deleteIndex(TEST_INDEX);
server.refresh(TEST_INDEX);


//Shutdown server
server.shutdown();
