symfony2 tdd developing - tdd

Question

Can anyone please provide a standard example for developing in Symfony2 using the TDD notation? Or share links to interesting materials for TDD Symfony2 development (except the official documentation :))?
P.S. Is anybody writing unit tests for controller part of MVC pattern?

Answer 1

I just did it for silex, which is a micro-framework based on Symfony2. From what I understand, it's very similar. I'd recommend it for a primer to the Symfony2-world.
I also used TDD to create this application, so what I did was:
I wrote my first test to verify the route/action
Then I implemented the route in my bootstrap
Then I added assertions to my test e.g., what should be displayed
I implemented that in my code and so on
An example testcase (in tests/ExampleTestCase.php) looks like this:
<?php
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 () {
return new ArraySessionStorage();
});
}
/**
* Test / (home)
*
* #return void
*/
public function testHome()
{
$client = $this->createClient();
$crawler = $client->request('GET', '/');
$this->assertTrue($client->getResponse()->isOk());
}
}
my bootstrap.php:
<?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 web/index.php:
<?php
$app = require './../bootstrap.php';
$app->run();
