Functional testing

Before we start writing our functional tests, we need to edit the phpunit.xml.dist file by adding our bundle Tests directory to the testsuite paths, as follows:

<testsuites>
  <testsuite name="Project Test Suite">
    <-- ... other elements ... -->
      <directory>src/AppBundle/Tests</directory>
    <-- ... other elements ... -->
  </testsuite>
</testsuites>

Our functional tests will cover only one controller, since we have no other. We start off by creating a src/AppBundle/Tests/Controller/DefaultControllerTest.php file with content as follows:

namespace AppBundle\Tests\Controller;

use Symfony\Bundle\FrameworkBundle\Test\WebTestCase;

class DefaultControllerTest extends WebTestCase
{
//…
}

The next step is to test each and every one of our controller ...
