The document discusses best practices for unit and functional testing PHP applications using PHPUnit. It covers setting up test directories and configuration files, creating test cases, making requests with the test client, and using assertions to validate responses. Functional tests are recommended over unit tests for application controllers. Techniques like request insulation and profiling responses are also described.

15. 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());

32. Simulate or use HTTP

33. $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);
}
