Testing Solr via Embedded Server

I'm coding some tests for my solr-indexer application. Following testing best practices, I want to write code self-dependant, just loading the schema.xml and solrconfig.xml and creating a temporary data tree for the indexing-searching tests. As the application is most written in java, I'm dealing with SolrJ library, but I'm getting problems (well, I'm lost in the universe of corecontainers-coredescriptor-coreconfig-solrcore ...) Anyone can place here some code to create an Embedded Server that loads the config and also writes to a parameter-pased data-dir?

First you need to set your Solr Home Directory which contains solr.xml and conf folder containing solrconfig.xml, schema.xml etc.

After that you can use this simple and basic code for Solrj.

File solrHome = new File("Your/Solr/Home/Dir/");
File configFile = new File(solrHome, "solr.xml");
CoreContainer coreContainer = new CoreContainer(solrHome.toString(), configFile);
SolrServer solrServer = new EmbeddedSolrServer(coreContainer, "Your-Core-Name-in-solr.xml");
SolrQuery query = new SolrQuery("Your Solr Query");
QueryResponse rsp = solrServer.query(query);
SolrDocumentList docs = rsp.getResults();
Iterator<SolrDocument> i = docs.iterator();
while (i.hasNext()) {
      System.out.println(i.next().toString());
}

I hope this helps.

You can start with the SolrExampleTests which extends SolrExampleTestBase which extends AbstractSolrTestCase .

Also this SampleTest.

Also take a look at this and this threads.

This is an example for a simple test case. solr is the directory that contains your solr configuration files:

import java.io.IOException;
import org.apache.solr.client.solrj.embedded.EmbeddedSolrServer;
import org.apache.solr.util.AbstractSolrTestCase;
import org.apache.solr.client.solrj.SolrQuery;
import org.apache.solr.client.solrj.SolrServer;
import org.apache.solr.client.solrj.SolrServerException;
import org.apache.solr.client.solrj.response.QueryResponse;
import org.apache.solr.common.SolrInputDocument;
import org.apache.solr.common.params.SolrParams;
import org.junit.Before;
import org.junit.Test;

import static org.junit.Assert.assertEquals;

public class SolrSearchConfigTest extends AbstractSolrTestCase {

    private SolrServer server;

    @Override
    public String getSchemaFile() {
        return "solr/conf/schema.xml";
    }

    @Override
    public String getSolrConfigFile() {
        return "solr/conf/solrconfig.xml";
    }

    @Before
    @Override
    public void setUp() throws Exception {
        super.setUp();
        server = new EmbeddedSolrServer(h.getCoreContainer(), h.getCore().getName());
    }

    @Test
    public void testThatNoResultsAreReturned() throws SolrServerException {
        SolrParams params = new SolrQuery("text that is not found");
        QueryResponse response = server.query(params);
        assertEquals(0L, response.getResults().getNumFound());
    }

    @Test
    public void testThatDocumentIsFound() throws SolrServerException, IOException {
        SolrInputDocument document = new SolrInputDocument();
        document.addField("id", "1");
        document.addField("name", "my name");

        server.add(document);
        server.commit();

        SolrParams params = new SolrQuery("name");
        QueryResponse response = server.query(params);
        assertEquals(1L, response.getResults().getNumFound());
        assertEquals("1", response.getResults().get(0).get("id"));
    }
}
