要为您的插件编写测试，您可以使用Elasticsearch Cluster
Runner。作为参考，请检查MinHash插件如何编写测试。
更新：
我将
CustomParserPluginTest类更改为使用Elasticsearch Cluster Runner：
import static org.prelibs.elasticsearch.runner.ElasticsearchClusterRunner.newConfigs;import java.util.Map;import junit.framework.TestCase;import org.prelibs.elasticsearch.runner.ElasticsearchClusterRunner;import org.elasticsearch.action.get.GetResponse;import org.elasticsearch.action.index.IndexResponse;import org.elasticsearch.client.Client;import org.elasticsearch.common.bytes.BytesArray;import org.elasticsearch.common.settings.ImmutableSettings;import org.elasticsearch.common.settings.ImmutableSettings.Builder;import org.elasticsearch.common.xcontent.XContentBuilder;import org.elasticsearch.common.xcontent.XContentFactory;import org.elasticsearch.index.get.GetField;import org.junit.Assert;import org.elasticsearch.action.search.SearchResponse;import static org.hamcrest.core.Is.is;public class CustomParserPluginTest extends TestCase { private ElasticsearchClusterRunner runner; @Override protected void setUp() throws Exception { // create runner instance runner = new ElasticsearchClusterRunner(); // create ES nodes runner.onBuild(new ElasticsearchClusterRunner.Builder() { @Override public void build(final int number, final Builder settingsBuilder) { } }).build(newConfigs().ramIndexStore().numOfNode(1)); // wait for yellow status runner.ensureYellow(); } @Override protected void tearDown() throws Exception { // close runner runner.close(); // delete all files runner.clean(); } public void test_jsonParsing() throws Exception { final String index = "test_index"; runner.createIndex(index, ImmutableSettings.builder().build()); runner.ensureYellow(index); final SearchResponse test = runner.client().prepareSearch(index).setSource(addQuery()).execute().actionGet(); } private String addQuery() { return "{"match_all":{"boost":1.2}}"; }}我创建了
es-plugin.properties（pluginrootdirectory src main
resources）文件，其内容如下，这将迫使elasticsearch实例加载插件：
plugin=CustomQueryParserPlugin
当您运行此测试时，您将在输出中看到新创建的Elasticsearch实例加载了插件。

希望这可以帮助。
