+### Example with DbUnit
+
+If you with to use Database fixture, use class `WebDbTestCase`. Caution: make sure the names you use for you fixture models won't conflict with your actual DB tables.

+```php
+class LocalDbWebTestCase extends \There4\Slim\Test\WebDbTestCase {
+	/**
+	 * You must implement this method
+	 * @return PHPUnit_Extensions_Database_DataSet_IDataSet
+	 */
+	public function getDataSet() {
+		return $this->createFlatXMLDataSet(dirname(__FILE__) . DIRECTORY_SEPARATOR . 'fixture.xml');
+	}
+}
+```
