unit-testing - 如何编写弹性单元测试以测试查询构建

Question

我想编写测试 flex 查询构建的单元测试。我想测试某些参数值会产生某些查询。

我开始研究ESTestCase。我看到您可以使用ESTestCase模拟客户端。我真的不需要模拟ES节点，只需要重现查询构建部分，但这需要客户端。

有人处理过这个问题吗？

import java.util.ArrayList;
import java.util.HashMap;
import java.util.Map;

import org.elasticsearch.action.search.SearchRequestBuilder;
import org.elasticsearch.client.Client;
import org.elasticsearch.client.transport.TransportClient;
import org.elasticsearch.common.settings.Settings;
import org.elasticsearch.common.unit.DistanceUnit;
import org.elasticsearch.test.ESIntegTestCase;
import org.elasticsearch.test.ESTestCase;
import org.junit.AfterClass;
import org.junit.BeforeClass;
import org.junit.Ignore;
import org.junit.Test;

import com.google.common.collect.Lists;

public class SearchRequestBuilderTests extends ESTestCase {
    private static Client client;

    @BeforeClass
    public static void initClient() {
        //this client will not be hit by any request, but it needs to be a non null proper client
        //that is why we create it but we don't add any transport address to it
        Settings settings = Settings.builder()
            .put("", createTempDir().toString())
            .build();

        client = TransportClient.builder().settings(settings).build();
    }

    @AfterClass
    public static void closeClient() {
        client.close();
        client = null;
    }

    public static Map<String, String> createSampleSearchParams() {
        Map<String, String> searchParams = new HashMap<>();
        searchParams.put(SenseneConstants.ADC_PARAM, "US");
        searchParams.put(SenseneConstants.FETCH_SIZE_QUERY_PARAM, "10");
        searchParams.put(SenseneConstants.QUERY_PARAM, "some query");
        searchParams.put(SenseneConstants.LOCATION_QUERY_PARAM, "");
        searchParams.put(SenseneConstants.RADIUS_QUERY_PARAM, "20");
        searchParams.put(SenseneConstants.DISTANCE_UNIT_PARAM, DistanceUnit.MILES.name());
        searchParams.put(SenseneConstants.GEO_DISTANCE_PARAM, "true");

        return searchParams;
     }

    @Test
    public void test() {
        BasicSearcher searcher = new BasicSearcher(client); // this is my application's searcher
        Map<String, String> searchParams = createSampleSearchParams();

        ArrayList<String> filterQueries = Lists.newArrayList();
        SearchRequest searchRequest = SearchRequest.create(searchParams, filterQueries);

        MySearchRequestBuilder medleyReqBuilder = new MySearchRequestBuilder.Builder(client, "my_index", searchRequest).build();
        SearchRequestBuilder searchRequestBuilder = medleyReqBuilder.constructSearchRequestBuilder();
        System.out.print(searchRequestBuilder.toString());
    // Here I want to assert that the search request builder output is what it should be for the above client params    
    }
}

我明白了，代码中什么也没有运行:

 Assertions mismatch: -ea was not specified but -Dtests.asserts=true
 REPRODUCE WITH: mvn test -Pdev -Dtests.seed=5F09BEDD71BBD14E -      Dtests.class=SearchRequestBuilderTests -Dtests.locale=en_US -Dtests.timezone=America/Los_Angeles

显然有点晚了，但是...

因此，这实际上与ES测试框架无关，而与您的运行设置无关。假设您正在eclipse中运行它，则实际上是Assertions mismatch: -ea was not specified but -Dtests.asserts=true的副本。

eclipse首选项-> junit->添加-ea复选框启用。

右键单击eclipse项目->运行方式->运行配置->参数选项卡->在vm参数

中添加-ea选项
