我创建了自定义的 Elasticsearch 插件。现在,我想为此插件编写一个测试。我的期望是-我可以运行嵌入式 Elasticsearch 实例,对其进行正确设置,然后进行一些测试(对一些文档进行索引,然后对其进行查询)
问题是我无法正确设置插件
自定义插件代码正在解析JSON查询并设置一些对象供以后使用:
public class CustomQueryParserPlugin extends AbstractPlugin { public static final String PLUGIN_NAME = "custom_query"; private final Settings settings; @Inject public CustomQueryParserPlugin (Settings settings) { this.settings = settings; } @Override public String name() { return PLUGIN_NAME; } @Override public String description() { return "custom plugin"; } public void onModule(IndicesQueriesModule module) { module.addQuery(new CustomQueryParser(settings)); } }
测试代码:
public class CustomParserPluginTest extends ElasticsearchSingleNodeTest { private static Node newNode() { final Settings settings = ImmutableSettings.builder() .put(ClusterName.SETTING, nodeName()) .put("node.name", nodeName()) .put(IndexMetaData.SETTING_NUMBER_OF_SHARDS, 1) .put(IndexMetaData.SETTING_NUMBER_OF_REPLICAS, 0) .put(EsExecutors.PROCESSORS, 1) // limit the number of threads created .put("http.enabled", false) .put("plugin.types", CustomParserPlugin.class.getName()) .put("path.plugins", pathToPlugin) .put("index.store.type", "ram") .put("config.ignore_system_properties", true) // make sure we get what we set :) .put("gateway.type", "none").build(); Node build = NodeBuilder.nodeBuilder().local(true).data(true).settings( settings).build(); build.start(); assertThat(DiscoveryNode.localNode(build.settings()), is(true)); return build; } @Test public void jsonParsing() throws URISyntaxException { final Client client = newNode().client(); final SearchResponse test = client.prepareSearch("test-index").setSource(addQuery()).execute().actionGet(); } private String addQuery() { return "{"match_all":{"boost":1.2}}" }
我已经为 pathToPlugin 尝试了多个值-但似乎没有什么效果很好,因为JSON查询总是给我一个例外:
QueryParsingException[[test-index] No query registered for [custom_query]];
我能找到的所有文档都是关于安装插件并在某些本地Elasticsearch安装上对其进行测试。
我在这里做错了什么?是否有类似的文档或测试示例?
UPD 。这是一个带有CustomQueryParserPlugin提取代码的仓库-https: //github.com/MysterionRise/es-custom- parser
可能在测试中的初始化部分中,我需要在内存中创建索引吗?
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:
CustomParserPluginTest
import static org.codelibs.elasticsearch.runner.ElasticsearchClusterRunner.newConfigs; import java.util.Map; import junit.framework.TestCase; import org.codelibs.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:
es-plugin.properties
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。
