Functional Tests

16.
Do not write Unit Tests for a Controller

17.
namespace ApplicationHelloBundleTestsController;
use SymfonyFrameworkWebBundleTestWebTestCase;
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());
}
}

18.
$client = $this->createClient();
$crawler = $client->request(
'GET', '/hello/Fabien');
$this->assertTrue($crawler->filter(
'html:contains("Hello Fabien")')->count());

19.
Environment Debug mode
$this->createClient('test', true);

20.
# hello/config/config_test.yml
imports:
- { resource: config_dev.yml }
web.config:
toolbar: false
zend.logger:
priority: debug
kernel.test: ~

21.
The Client makes requests to the Symfony2 application
The Crawler parses the Response to allow navigation
The PHPUnit Assertions tests the Response

22.
Assertions

23.
$this->assertEquals(
10,
$crawler->filter('div.hentry')->count());
$this->assertTrue(
$client->getResponse()->isSuccessful());

24.
The Client / The Crawler

25.
$crawler = $client->request(
'GET', 'hello/Lucas'
);

26.
$link = $crawler->selectLink("Greet Lucas");
$client->click($link);

27.
$form = $crawler->selectButton('submit');
$client->submit($form, array(
'name' => 'Lucas',
'country' => 'France',
'like_symfony' => true,
'photo' => '/path/to/lucas.jpg',
));

28.
$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());

29.
$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());
