{
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);
}
}
?>

<?php
class CountTest extends PHPUnit_Framework_TestCase
{
public function testCount()
{
$this->assertCount(3,array(1,2,3));
}
}
?>

24. AssertContains

class ContainsTest extends PHPUnit_Framework_TestCase
{
public function testContainsOK()
{
$this->assertContains('cerca',
'chi cerca trova');
}
}
?>

25. AssertContains

26. ORGANIZZAZIONE

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 AcmeStoreBundleTestsEntity;
use SymfonyBundleFrameworkBundleTestWebTestCase;
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 AcmeDemoBundleTestsController;
use SymfonyBundleFrameworkBundleTestWebTestCase;
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() );
}
}

--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
