Further steps

  • For now, you'll need to run singlethreaded, because the EmbeddedSolrServer locks the indexdirectory (see pom.xml for configuration of surefire.)
  • We usually put our Solr Configs in src/main/resources or src/test/resources
  • Have your JUnit test extend SolrTestCase
  • Test your schema and solrconfig.xml

Examples

Example setup is available for both maven and gradle inside the exampleprojects folder

Maven

Gradle

Exampletest

import no.finn.solr.integration.SolrTestCase;

public class SolrConfigTest extends SolrTestCase {
    @Test
    public void weCanFindADocumentWeJustAdded() throws Exception {
        Long docId = solr.addDocumentWith("Hello");
        solr.performSearchAndAssertHits("hello", docId);
    }
}

For other examples - see the provided SolrExampleTestCase

How to Use

Our goal is that the Javadocs should be all you need.

But a quickstart is available below:

Adding documents (indexing)

Adding a single document with a string value to default field

Long docId = solr.addDocumentWith(content);

Adds a single document to the index with content to what is set as defaultContentField. By default this is the body field. Returns the randomly generated id of the document. The id can be used later for verification

Adding several values to default field

Long[] docIds = solr.addDocumentsWith(... content);

A varargs version of addDocumentWith, this adds content to the defaultContentField Returns an array of the documentIds acquired when adding the content

Adding a single document with value to custom field

Long docIds = solr.addDocumentWithField(field, content);

Adds a single document to the index with content to the field in field Returns the randomly generated id of the document

Adding several values to custom field

Long[] docIds = solr.addDocumentsWithField(field, ... content);

A varargs version of addDocumentWithField. This adds contents to the field Returns an array of the documentIds acquired when adding the content

Searching

Search using default search handler

QueryResponse response = solr.search(String query);

Search using dismax search handler

QueryResponse response = solr.dismaxSearch(String dismaxQuery);

Uses the dismax queryhandler instead of the standard/default handler (qt=dismax). This performs a search and updates the response field on the class. Call

Search for specified field with value

solr.search(field, query);

Offers a simple way to run a query against a specific field

Performing search with custom parameters set

If you've set parameters directly on SolrClient or with solr.withParam(..) you can execute a search by calling

QueryResponse response = solr.search();

This will then perform a search with the parameters currently set.

Asserts / Checks

Search and find one document

solr.performSearchAndAssertOneHit(String search);

Calls search, and then verifies that the result has exactly one hit

Search and verify ids of documents

solr.performSearchAndAssertHits(String search, Long... ids);

Calls search, and then verifies that the hits returned have exactly the ids passed in. Works well with the ids returned from the solr.addDocument_ methods

Search and verify not found

solr.performSearchAndAssertNoHits(String search);

Typically you'd want to confirm that a certain word does not yield results

import no.finn.solr.integration.SolrTestCase;

public class NonExistantDocumentTest extends SolrTestCase {
    @Test
    public void documentDoesNotExist() throws Exception {
      Long docId = solr.addDocumentWith("doc");
      solr.performSearchAndAssertNoHits("doctor");
    }
}

Makes sure that the index does not contain anything that matches the passed in search
