copied!<p>So far I've understood that: <strong>Should I create a testdb database or is that all emulated/virtual ?</strong></p> <p>It create a real database, and using the getSetUpOperation method, it's really slow as the tables are truncated and re-imported for each test, and it's demanding alot on the harddrive even for a small amount of data. ( ~ 1 sec/test )</p> <p><strong>I've seen many examples using sqlite::memory: , is it a good idea to test MySQL based query with sqlite ? Can I use mysql::memory: instead ?</strong></p> <p>I still don't know. I think it's now really possible with MySQL.</p> <p><strong>If it's a real DB, how do I restore all the data from dbData.xml in the DB before each test run ?</strong></p> <p>There are getSetUpOperation and getTearDownOperation that act like setup and tearDown method. Adding this will truncate the table mentionned in the dataSet, and re-insert all the data of that xml file:</p> <pre><code>/** * Executed before each * * @return PHPUnit_Extensions_Database_Operation_DatabaseOperation */ protected function getSetUpOperation() { return PHPUnit_Extensions_Database_Operation_Factory::CLEAN_INSERT(); } </code></pre> <p><strong>Where am I supposed to call getConnection() and getDataSet() ?</strong></p> <p>Nowhere. Theses are magic method that are called automatically. getConnection is called before the tests ( a bit like __construct would be, but I'm not sure about the order ) and getDataSet will be called when a dataSet is needed. I <em>think</em> that in my case, only getSetUpOperation have a dependency for a dataSet... so in the background it calls the getDataSet method before each tests to make the CLEAN_INSERT operation.</p> <p>Also, I discovered that we need to create the table structure ( the dataset doesn't handle that ), so my full --slow-- working code is:</p> <pre><code><?php require_once 'PHPUnit/Extensions/Database/TestCase.php'; class NewsFactoryTest extends PHPUnit_Extensions_Database_TestCase { /** * Custom PDO instance required by the SUT. * * @var Core_Db_Driver_iConnector */ protected $db; /** * Create a connexion. * Note: les constantes de connexion sont définit dans bootstrap.php. * * @return PHPUnit_Extensions_Database_DB_IDatabaseConnection */ protected function getConnection() { //Instanciate the connexion required by the system under test. $this->db = new Core_Db_Driver_PDO('mysql:host=' . TEST_DB_HOST . ';dbname=' . TEST_DB_BASE, TEST_DB_USER, TEST_DB_PASS, array()); //Create a genuine PDO connexion, required for PHPUnit_Extensions_Database_TestCase. $db = new PDO('mysql:host=' . TEST_DB_HOST . ';dbname=' . TEST_DB_BASE, TEST_DB_USER, TEST_DB_PASS); $this->createTableSchema($db); return $this->createDefaultDBConnection($db, TEST_DB_BASE); } /** * Load the required table schemes. * * @param PDO $db * @return void */ protected function createTableSchema(PDO $db) { $schemaPath = dirname(__FILE__) . DIRECTORY_SEPARATOR . 'sql_schema' . DIRECTORY_SEPARATOR; $query = file_get_contents($schemaPath . 'news.sql'); $db->exec($query); $query = file_get_contents($schemaPath . 'news_locale.sql'); $db->exec($query); } /** * Load the dataSet in memory. * * @return PHPUnit_Extensions_Database_DataSet_IDataSet */ protected function getDataSet() { return $this->createXMLDataSet(dirname(__FILE__) . DIRECTORY_SEPARATOR . 'newsFactory_dataSet.xml'); } /** * Method executed before each test * * @return PHPUnit_Extensions_Database_Operation_DatabaseOperation */ protected function getSetUpOperation() { //TRUNCATE the table mentionned in the dataSet, then re-insert the content of the dataset. return PHPUnit_Extensions_Database_Operation_Factory::CLEAN_INSERT(); } /** * Method executed after each test * * @return PHPUnit_Extensions_Database_Operation_DatabaseOperation */ protected function getTearDownOperation() { //Do nothing ( yup, their's a code for that ) return PHPUnit_Extensions_Database_Operation_Factory::NONE(); } /** * @covers NewsFactory::getNewsById */ public function testGetNewsById() { $newsFactory = new NewsFactory($this->db); $news = $newsFactory->getNewsById(999); $this->assertFalse($news); } } </code></pre> <p>Hope that will help other people that needed some extra explanations. If you have any comment, suggestion or idea, your input is welcome, as I don't consider this solution as a fully efficient one. ( Slow and long to setup, and needs a double connection. )</p>
