Symfony2 TDD development

 use Silex\WebTestCase;
use Symfony\Component\HttpFoundation\SessionStorage\ArraySessionStorage;

class ExampleTestCase extends WebTestCase

 /* *
 * Necessary to make our application testable.

Can anyone provide A standard example of developing in Symfony2 using TDD notation? Or share links to interesting materials about TDD Symfony2 development (official documentation:))?

Attachment: Does anyone write unit tests for the controller part of the MVC pattern?

I just made this for silex, which is a micro-framework based on Symfony2. As far as I know, it is very similar. I recommend it as Symfony2 World

I also used TDD to create this application, so what I did was:

>I wrote the first test to verify the route/action
> Then I implemented routing in my bootstrap
> Then I added assertions in my test, for example, what should be displayed
> I implemented this in my code, etc. Etc.

The example test case (in tests/ExampleTestCase.php) is as follows:

use Silex\WebTestCase; 
use Symfony\Component\HttpFoundation\SessionStorage\ArraySessionStorage;

class ExampleTestCase extends WebTestCase
{
 /**
 * Necessary to make our application testable .
 *
 * @return Silex\Application
 */
 public function createApplication()
 {
 return require __DIR__.'/../bootstrap .php';
 }

 /**
 * Override NativeSessionStorage
 *
 * @return void
 */
 public function setUp()
 {
 parent::setUp();
 $this->app['session.storage'] = $this->app->share(function () {
 re turn new ArraySessionStorage();
 });
 }

 /**
 * Test / (home)
 *
 * @ return void
 */
 public function testHome()
 {
 $client = $this->createClient();
 $crawler = $client->request( 'GET','/');

 $this->assertTrue($client->getResponse()->isOk());
 }
}

My bootstrap.php:

require_once __DIR__.'/vendor/silex.phar';

$app = new Silex\Application();

// load session extensions
$app->register(new Silex\Extension\SessionExtension());

$app->get('/home', function() use ($app) {
 return "Hello World";
});
return $app;

My website/index.php:

$app = require'./../bootstrap.php';
$app->run();
