I am using Elasticsearch 2.2.0 where I am trying to run the following test case:
package com.animesh.elasticsearch.plugin;
import org.elasticsearch.action.admin.indices.template.put.PutIndexTemplateResponse;
import org.apache.commons.io.IOUtils;
import org.elasticsearch.plugins.Plugin;
import org.elasticsearch.test.ESIntegTestCase;
import org.junit.Assert;
import org.junit.Test;
import java.io.IOException;
import java.util.Collection;
@ESIntegTestCase.ClusterScope(scope = ESIntegTestCase.Scope.SUITE, numDataNodes = 0)
public class NewPluginTest extends ESIntegTestCase {
private final static String indexName = "new_index";
private final static String templateJson = "template.json";
private final static String templateName = "F:\\ESPluginTest\\src\\test\\resources\\template.json";
@Override
protected Collection<Class<? extends Plugin>> nodePlugins() {
return pluginList(NewSimilarityPlugin.class);
}
@Test
public void IndexExists() throws IOException {
try {
String currentTemplate = IOUtils.toString(getClass().getResourceAsStream(templateJson));
assertNotNull("The template should not be null", currentTemplate);
PutIndexTemplateResponse response = client().admin()
.indices()
.preparePutTemplate(templateName)
.setSource(currentTemplate)
.execute()
.actionGet();
if (!response.isAcknowledged())
Assert.fail("Could not create the template");
assertNotNull(getResponse.getIndexTemplates());
assertThat(getResponse.getIndexTemplates(), hasSize(1));
} catch (Exception e) {
Assert.fail("There was some error in defining the template");
}
}
}
Here NewSimilarityPlugin is a plugin that I designed for customizing default scoring.
Following is the error stack trace that I get:

UPDATE:
I noticed that client()'s value is null which is causing this issue.
