How to Simulate 500 Error in Symfony 2

Question

I am wondering how would I simulate a 500 error in Symfony 2.

I have been reading this post where Raise suggests throwing an exception

Answer 1

A good way to do it can be:

use Symfony\Component\HttpKernel\Exception\HttpException;

throw new HttpException(\Symfony\Component\HttpFoundation\Response::HTTP_INTERNAL_SERVER_ERROR, 'Testing the 500 error');

Answer 2

You can do it like this.

//in your controller
$response = new Response();
$response->setStatusCode(500);
return $response;

Dont forget to add

use Symfony\Component\HttpFoundation\Response;

at the top of your file.

Edit : To force Symfony 500 error, your proposition is fine :

throw new \Exception('Something went wrong!');

Put it in a controller function.

Answer 3

You can do:

throw new Symfony\Component\HttpKernel\Exception\HttpException(500, "Some description");

Answer 4

The simplest way to do this is to:

return new Response('', 500);

Don't forget to include Symfony\Component\HttpFoundation\Response.

Answer 5

If you want to trigger a FatalErrorException in Symfony2 to see if you app is handling it correctly, you can create an action like this in your controller:

public function fatalErrorExceptionAction()
{
    $unknown->getVoid();
}

The division by zero will generate a Warning while throwing the Exception, well, it'll just throw it. :-)

Answer 6

You have to use Symfony\Component\HttpKernel\Exception\HttpException.

Another way should be doing something like 1/0;, but I haven't tested it.
