Making Symfony2 unit tests more DRY by extending WebTestCase

Question

A lot of my tests have a lot of the same setUp()/tearDown() stuff going on. It seems dumb to copy and paste the same code into every single one of my unit tests. I think I want to create a new test class that extends WebTestCase that my other tests can extend.

My problem is that I don't really know how. First of all, where's the most appropriate place to put this new class? I tried making one just inside my Tests folder, but then none of my tests could actually find the class. Maybe I just don't understand namespaces.

Has anyone extended WebTestCase before in the way I'm talking about? If so, how did you do it?

Answer 1

I haven't done this, but I'd probably just do it like so

src/Your/Bundle/Test/WebTestCase.php

<?php

namespace Your\Bundle\Test

use Symfony\Bundle\FrameworkBundle\Test\WebTestCase as WTC;

class WebTestCase extends WTC
{
  // Your implementation of WebTestCase
}

Answer 2

In my tests I usually extend the WebTestCase the way Peter proposed it. Additionally I use require_once to make the AppKernel available in my WebTestCase:

<?php

namespace My\Bundle\Tests;

use Symfony\Bundle\FrameworkBundle\Test\WebTestCase as BaseWebTestCase;

require_once(__DIR__ . "/../../../../app/AppKernel.php");

class WebTestCase extends BaseWebTestCase
{
  protected $_application;

  protected $_container;

  public function setUp()
  {
    $kernel = new \AppKernel("test", true);
    $kernel->boot();
    $this->_application = new \Symfony\Bundle\FrameworkBundle\Console\Application($kernel);
    $this->_application->setAutoExit(false);

...

My tests then look like this:

<?php

namespace My\Bundle\Tests\Controller;

use My\Bundle\Tests\WebTestCase;

class DefaultControllerTest extends WebTestCase
{
    public function testIndex()
    {
...
