README

ElasticSearchUnit is a PHPUnit extension for test cases that utilize the official ElasticSearch Client as their data source.

Requirements

• PHP 5.4+
• ElasticSearch 1.7+

Testing

1. Install dependencies composer install -dev
2. Run ./bin/phpunit

Example use

<?php

class MyElasticSearchTestCase extends \PHPUnit_Framework_TestCase {
	use \Zumba\PHPUnit\Extensions\ElasticSearch\TestTrait;

	/**
	 * Get the ElasticSearch connection for this test.
	 *
	 * @return Zumba\PHPUnit\Extensions\ElasticSearch\Client\Connector
	 */
	public function getElasticSearchConnector() {
		if (empty($this->connection)) {
			$clientBuilder = new \Elasticsearch\ClientBuilder();
			$this->connection = new \Zumba\PHPUnit\Extensions\ElasticSearch\Client\Connector($clientBuilder->build());
		}
		return $this->connection;
	}

	/**
	 * Get the dataset to be used for this test.
	 *
	 * @return Zumba\PHPUnit\Extensions\ElasticSearch\DataSet\DataSet
	 */
	public function getElasticSearchDataSet() {
		$dataset = new \Zumba\PHPUnit\Extensions\ElasticSearch\DataSet\DataSet($this->getElasticSearchConnector());
		$dataset->setFixture([
			'some_index' => [
				'some_type' => [
					['name' => 'Document 1'],
					['name' => 'Document 2']
				]
			]
		]);
		return $dataset;
	}

	public function testRead() {
		$result = $this->getElasticSearchConnector()->getConnection()->search(['index' => 'some_index']);
		$this->assertEquals(2, $result['hits']['total']);
	}

}

Testing with Docker/VM etc

If Elasticsearch is not running on localhost, you can provide the hostname of your Elasticsearch instance via environment variables:

ES_TEST_HOST=http://docker:9200 ./bin/phpunit

Elasticsearch Version Support

For Elasticsearch 5.x and greater, use version 2.x.

For Elasticsearch 2.x/1.x, use the version 1.x.

Note about PHPUnit Versions

It currently is supporting PHPUnit 4 @before and @after but can be used in PHPUnit ~3.7 by either aliasing the elasticSearchSetUp and elasticSearchTearDown to setUp and tearDown, or by calling elasticSearchSetUp and elasticSearchTearDown in your respective methods.
