AssertTrue

<?php
class TrueTest extends PHPUnit_Framework_TestCase
{
    public function testTrue()
    {
        $this->assertTrue(true);
    }
}
?>

AssertEquals

<?php
class EqualsTest extends PHPUnit_Framework_TestCase
{
    public function testEquals()
    {
        $this->assertEquals('uguale', 'uguale');
    }
}
?>

AssertEquals
<?php
class EqualsTest extends PHPUnit_Framework_TestCase
{
    public function testObjectsAreEqual()
    {
        $this->assertEquals(new stdClass,
new stdClass);
    }
}
?>

AssertCount

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

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

AssertContains

<?php
class ContainsTest extends PHPUnit_Framework_TestCase
{
    public function testArrayContains()
    {
        $this->assertContains(‘ragno’,
array(‘ragno’,‘nel’,‘buco’));
    }
}
?>

ORGANIZZAZIONE

http://phpunit.de/manual/3.7/en/organizing-tests.html

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());
    }
}

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()
        ;
    } ...

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();
    }
}

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');
    }
}

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() );
    }
}
