Functional testing

The auto-generate CRUD tool generated the CustomerControllerTest.php file for us within the src/Foggyline/CustomerBundle/Tests/Controller/ directory. In the previous chapter we showed how to pass an authentication parameter to static::createClient in order to make it simulate user logging. However, that is not the same login as our customers will be using. We are no longer using a basic HTTP authentication, rather a full blown login form.

In order to address the login form testing, let's go ahead and edit the src/Foggyline/CustomerBundle/Tests/Controller/CustomerControllerTest.php file as follows:

namespace Foggyline\CustomerBundle\Tests\Controller;

use Symfony\Bundle\FrameworkBundle\Test\WebTestCase;
use Symfony\Component\BrowserKit\Cookie;
use Symfony\Component\Security\Core\Authentication\Token\UsernamePasswordToken;

class CustomerControllerTest extends WebTestCase
{
  private $client = null;

  public function setUp()
  {
    $this->client = static::createClient();
  }

  public function testMyAccountAccess()
  {
    $this->logIn();
    $crawler = $this->client->request('GET', '/customer/account');

    $this->assertTrue($this->client->getResponse()->
      isSuccessful());
    $this->assertGreaterThan(0, $crawler->filter('html:contains("My Account")')->count());
  }

  private function logIn()
  {
    $session = $this->client->getContainer()->get('session');
    $firewall = 'foggyline_customer'; // firewall name
    $em = $this->client->getContainer()->get('doctrine')->getManager();
    $user = $em->getRepository('FoggylineCustomerBundle:Customer')->findOneByUsername('john@test.loc');
    $token = new UsernamePasswordToken($user, null, $firewall, array('ROLE_USER'));
    $session->set('_security_' . $firewall, serialize($token));
    $session->save();
    $cookie = new Cookie($session->getName(), $session->getId());
    $this->client->getCookieJar()->set($cookie);
  }
}

Here we first created the logIn method, whose purpose is to simulate the login, by setting up the proper token value into the session, and passing on that session ID to the client via a cookie. We then created the testMyAccountAccess method, which first calls the logIn method and then checks if the crawler was able to access the My Account page. The great thing about this approach is that we did not have to code in the user password, only its username.

Now, let's go ahead and address the customer registration form, by adding the following to the CustomerControllerTest:

public function testRegisterForm()
{
  $crawler = $this->client->request('GET', '/customer/register');
  $uniqid = uniqid();
  $form = $crawler->selectButton('Register!')->form(array(
    'customer[email]' => 'john_' . $uniqid . '@test.loc',
    'customer[username]' => 'john_' . $uniqid,
    'customer[plainPassword][first]' => 'pass123',
    'customer[plainPassword][second]' => 'pass123',
    'customer[firstName]' => 'John',
    'customer[lastName]' => 'Doe',
    'customer[company]' => 'Foggyline',
    'customer[phoneNumber]' => '00 385 111 222 333',
    'customer[country]' => 'HR',
    'customer[state]' => 'Osijek',
    'customer[city]' => 'Osijek',
    'customer[postcode]' => '31000',
    'customer[street]' => 'The Yellow Street',
  ));

  $this->client->submit($form);
  $crawler = $this->client->followRedirect();
  //var_dump($this->client->getResponse()->getContent());
  $this->assertGreaterThan(0, $crawler->filter('html:contains("customer/login")')->count());
}

We have already seen a test similar to this one in the previous chapter. Here we are merely opening a customer/register page, then finding a button with Register! label, so we can fetch the entire form through it. We then set all of the required form data, and simulate the form submit. If successful, we observe for the redirect body and assert against value expected in it.

Running the phpunit command now should successfully execute our tests.
