Failed asserting the HTTP status code is 200 not 500

Question

I'm trying to functional test the HTTP status code for a certain request is 200 not 500. I'm using Symfony2, and here's the code:

public function testIndex()
{
    $client = static::createClient();
    $crawler = $client->request('GET', "/");
    $this->assertEquals('Ibw\JobeetBundle\Controller\JobController::indexAction', $client->getRequest()->attributes->get('_controller'));
    $this->assertEquals(200 , $client->getResponse()->getStatusCode());
    $this->assertEquals(0, $crawler->filter('.jobs td.position:contains("Expired")')->count());
}

And the result :

1) Ibw\JobeetBundle\Tests\Functional\JobControllerTest::testIndex Failed asserting that 500 matches expected 200.

When I access the route "/" manually through the browser it works just fine.

So what's wrong here ?

Solution

The 500 error can be caused by anything in your case.

What you could do in such situation is to dump the content of the response and check the Symfony debugging message.

I usually use such code snippet for quick checking such errors directly in terminal:

if (!$response->isSuccessful()) {
    $block = $crawler->filter('div.text_exception > h1');
    if ($block->count()) {
        $error = $block->text();
    }
}

where div.text_exception > h1 is the xpath from Symfony2 debug page to the message itself

Then just print the $error
