ORGANIZZAZIONE

Tipologie

UNIT

Unit Test<?phpclass MyClass{    public function hello()    {        return ‘Ciao!’;    }}class MyClassTest extends PHPUnit_Framework_TestCase{    public function testHello()    {

$class = new MyClass();        $this->assertEquals(‘Ciao!’, $class->hello());    }}

Integration

Integration Test<?phpnamespace 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()        ;    } ...

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

Functional Test<?phprequire_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 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() );    }}
