testing symfony API authenticated - unable to find template

Question

I try to write tests for my symfony API (symfony version : 3.4).

My symfony project is made to be the API. I use fosRest bundle

I have this error when trying to call an entry point :

Unable to find template "" (looked into: C:\wamp64\www\myproject\src\app/Resources/views, C:\wamp64\www\myproject\src\vendor\symfony\symfony\src\Symfony\Bridge\Twig/Resources/views/Form).

When i run my test with xdebug, it passes in my controller and get the result i need.

In HttpKernel i see my entity at this line :

$response = \call_user_func_array($controller, $arguments);

But after this line, it goes in the view block and returns me this error.

Is this a config problem ?

entry point in my controller :

/**
 * @param $id
 * @Get("/metiers/{id}")
 * @return \AppBundle\Entity\Metier
 */
public function getMetierAction($id)
{
    return $this->getDoctrine()->getManager()->getRepository('AppBundle:Metier')->findOneById($id);
}

Here is my test :

    $client = static::createClient([], [
        'PHP_AUTH_USER' => 'myuser',
        'PHP_AUTH_PW'   => 'pa$$word',
    ]);

    $client->request('GET', 'http://myproject.localhost/metiers/1');
    $response = $client->getResponse();
    $content = json_decode($response->getContent(), true);

my config_test.yml file :

imports:
- { resource: parameters_test.yml }
- { resource: config.yml }

framework:
    test: true

security:
    firewalls:
        # replace 'main' by the name of your own firewall
        main:
            http_basic: ~

callStack in xdebug :

InvalidArgumentException: Unable to find template "" (looked into: C:\wamp64\www\myproject\src\app/Resources/views, C:\wamp64\www\myproject\src\vendor\symfony\symfony\src\Symfony\Bridge\Twig/Resources/ views/Form). in C:\wamp64\www\myproject\src\vendor\symfony\symfony\src\Symfony\Bridge\Twig\TwigEngine.php on line 127

What kind of API is this? What packages are you using? How does your controller look like? — Nicolai Fröhlich

Problem solved adding this to the config_test.yml file :

fos_rest:
    format_listener:
        rules:
            - { path: '^/api', fallback_format: json }
            - { path: '^/', fallback_format: json }
