Symfony: Getting basic routing to work - symfony

Question

this maybe due to my stupidity, but I could really use a hint here.
I have not done much with php so far, been mostly working with javascript, and now trying to get a grasp on Symfony. I'm working with vagrant and the great scotch-box, so I installed Symfony on this vm and created a new app. I tried creating a route that just returns "Hello world!", but i can't get it to work.
The route defined in the DefaultController is working. I created a new controller via the console command
$ php bin/console generate:controller
and called it TestController. This is it:
<?php
namespace AppBundle\Controller;
use Sensio\Bundle\FrameworkExtraBundle\Configuration\Route;
use Symfony\Bundle\FrameworkBundle\Controller\Controller;
use Symfony\Component\HttpFoundation\Request;
use Symfony\Component\HttpFoundation\Response;
class TestController extends Controller
{
/**
* #Route("/test")
*/
public function testAction()
{
return new Response( "Hello World!" );
}
}
When navigating to [scotch-box address]/my_project/web I get the default route, but [scotch-box address]/my_project/web/test gives me a 404.
Maybe it has to do with the configuration of the vm, but this is not my expertise, so any nudge in the right direction will be appreciated. Thank you!
Edit: After I managed to destroy my vm yesterday, I set up a clean scotch-box and installed symfony's demo-app, which is running just fine. I also have setup a clean Symfony project and changed only the DefaultController's route to "/home":
<?php
namespace AppBundle\Controller;
use Sensio\Bundle\FrameworkExtraBundle\Configuration\Route;
use Symfony\Bundle\FrameworkBundle\Controller\Controller;
use Symfony\Component\HttpFoundation\Request;
class DefaultController extends Controller
{
/**
* #Route("/home", name="homepage")
*/
public function indexAction(Request $request)
{
// replace this example code with whatever you need
return $this->render('default/index.html.twig', [
'base_dir' => realpath($this->container->getParameter('kernel.root_dir').'/..'),
]);
}
}
my routing.yml reads:
app:
resource: "#AppBundle/Controller/"
type: annotation
As I understand it, Symfony's welcome page should now be reachable via [scotch-box address]/my_project/web/home, but it isn't. Instead I can still reach it via [scotch-box address]/my_project/web, while /home throws a 404 page.
Maybe I'm wearing the idiot hat here, but I could not find anything in the documentation that would shed a light on this.

I may be wrong, but I'm pretty sure that it's because your routing.yml file is incomplete. Check if you have this in routing.yml:
app:
resource: "#AppBundle/Controller/"
type: annotation
If not, add it. This will "plug in" the annotation routing of your AppBundle into the routing of the whole project.
