20. AssertTrue <?php class TrueTest extends PHPUnit_Framework_TestCase { public function testTrue() { $this->assertTrue(true); } } ?>
21. AssertEquals <?php class EqualsTest extends PHPUnit_Framework_TestCase { public function testEquals() { $this->assertEquals('uguale', 'uguale'); } } ?>
22. AssertEquals <?php class EqualsTest extends PHPUnit_Framework_TestCase { public function testObjectsAreEqual() { $this->assertEquals(new stdClass, new stdClass); } } ?>
23. AssertCount <?php class CountTest extends PHPUnit_Framework_TestCase { public function testCount() { $this->assertCount(3,array(1,2,3)); } } ?>
24. AssertContains <?php class ContainsTest extends PHPUnit_Framework_TestCase { public function testContainsOK() { $this->assertContains('cerca', 'chi cerca trova'); } } ?>
25. AssertContains <?php class ContainsTest extends PHPUnit_Framework_TestCase { public function testArrayContains() { $this->assertContains(‘ragno’, array(‘ragno’,‘nel’,‘buco’)); } } ?>
26. ORGANIZZAZIONE http://phpunit.de/manual/3.7/en/organizing-tests.html
27. Tipologie
28. UNIT
29. Unit Test <?php class MyClass { public function hello() { return ‘Ciao!’; } } class MyClassTest extends PHPUnit_Framework_TestCase { public function testHello() { $class = new MyClass(); $this->assertEquals(‘Ciao!’, $class->hello()); } }
30. Integration
31. Integration Test <?php namespace Acme\StoreBundle\Tests\Entity; use Symfony\Bundle\FrameworkBundle\Test\WebTestCase; class ProductRepositoryFunctionalTest extends WebTestCase { private $em; public function setUp() { static::$kernel = static::createKernel(); static::$kernel->boot(); $this->em = static::$kernel->getContainer() ->get('doctrine') ->getManager() ; } ...
32. Integration Test ... public function testSearchByCategoryName() { $products = $this->em ->getRepository('AcmeStoreBundle:Product') ->searchByCategoryName('foo') ; $this->assertCount(1, $products); } protected function tearDown() { parent::tearDown(); $this->em->close(); } }
33. Functional
34. Functional Test <?php require_once 'PHPUnit/Extensions/SeleniumTestCase.php'; class WebTest extends PHPUnit_Extensions_SeleniumTestCase { protected function setUp() { $this->setBrowser('*firefox'); $this->setBrowserUrl('http://php.net/'); } public function testTitle() { $this->open('http://php.net/'); $this->assertTitle('PHP: Hypertext Preprocessor'); } }
35. Functional Test <?php namespace Acme\DemoBundle\Tests\Controller; use Symfony\Bundle\FrameworkBundle\Test\WebTestCase; class DemoControllerTest extends WebTestCase { public function testIndex() { $client = static::createClient(); $crawler = $client->request('GET', '/demo/hello/Fabio'); $this->assertGreaterThan( 0, $crawler->filter('html:contains("Hello Fabio")') ->count() ); } }
36. in azione
38. OUTPUT legenda http://phpunit.de/manual/3.7/en/textui.html . Eseguito con successo F Il test è fallito E Errore nell’esecuzione S Saltato (Skipped) I Non completo
41. comandi utili http://phpunit.de/manual/current/en/textui.html --verbose Mostra più informazioni, come il nome dei test saltati o incompleti --debug Mostra più informazioni, come il nome del test in esecuzione --stop-on-error Blocca il processo al primo errore --stop-on-failure Blocca il processo al primo fallimento di un test --filter [nome] Processa solo i test che contengono nel nome il termine passato
42. Test-Driven Development
