Functional Tests

Do not write Unit Tests for a Controller

namespace Application\HelloBundle\Tests\Controller;

use Symfony\Framework\WebBundle\Test\WebTestCase;

class HelloControllerTest extends WebTestCase { public function testIndex() { $client = $this->createClient(); $crawler = $client->request( 'GET', '/hello/Fabien');

$this->assertTrue($crawler->filter( 'html:contains("Hello Fabien")')->count()); } }

$client = $this->createClient();

$crawler = $client->request( 'GET', '/hello/Fabien');

$this->assertTrue($crawler->filter( 'html:contains("Hello Fabien")')->count());

$this->createClient('test', true);

Environment Debug mode

# hello/config/config_test.yml imports: - { resource: config_dev.yml }

web.config: toolbar: false

zend.logger: priority: debug

kernel.test: ~

The Client makes requests to the Symfony2 application

The Crawler parses the Response to allow navigation

The PHPUnit Assertions tests the Response

Assertions

$this->assertEquals( 10, $crawler->filter('div.hentry')->count());

$this->assertTrue( $client->getResponse()->isSuccessful());

The Client / The Crawler

$crawler = $client->request( 'GET', 'hello/Lucas' );

$link = $crawler->selectLink("Greet Lucas");

$client->click($link);

$form = $crawler->selectButton('submit');

$client->submit($form, array( 'name' => 'Lucas', 'country' => 'France', 'like_symfony' => true, 'photo' => '/path/to/lucas.jpg', ));

$harry = $this->createClient(); $sally = $this->createClient();

$harry->request('POST', '/say/sally/Hello'); $sally->request('GET', '/messages');

$this->assertEquals(201, $harry->getResponse()->getStatusCode());

$this->assertRegExp('/Hello/', $sally->getResponse()->getContent());

$harry = $this->createClient(); $sally = $this->createClient();

$harry->insulate(); $sally->insulate();

$harry->request('POST', '/say/sally/Hello'); $sally->request('GET', '/messages');

$this->assertEquals(201, $harry->getResponse()->getStatusCode()); $this->assertRegExp('/Hello/', $sally->getResponse()->getContent());

Simulate or use HTTP

$response = $client->getResponse(); $profiler = $this->getProfiler($response);

if ($profiler) { $this->assertEquals(2, $profiler['db']->getQueryCount());

$this->assertEquals('blog_post', $profiler['app']->getRoute());

$this->assertTrue( $profiler['timer']->getTime() < 0.5); }
