Symfony 5 and API-Platform 2.5 functional test for Not allowed method

I have Symfony 5 and API-Platform 2.5, just installed with flex. I created User entity as API Resource, the collection list must be forbidden, so I created a functional test to check it.

The test pass correctly but I get also an error:

$ ./vendor/bin/simple-phpunit --filter=UsersTest::testGetCollection
PHPUnit 7.5.20 by Sebastian Bergmann and contributors.

Testing Project Test Suite
2020-05-03T21:50:50+00:00 [error] Uncaught PHP Exception Symfony\Component\HttpKernel\Exception\MethodNotAllowedHttpException: "No route found for "GET /api/users": Method Not Allowed (Allow: POST)" at /srv/api/vendor/symfony/http-kernel/EventListener/RouterListener.php line 140
.                                                                   1 / 1 (100%)

OK (1 test, 1 assertion)

I Would like to hide the error message.

Here are the files:

User Class

/**
 * @ApiResource(collectionOperations={"post"}, itemOperations={"get"})
 * @ORM\Entity(repositoryClass="App\Repository\UserRepository")
 */
class User
{
   /* some code */
}

Test

class UsersTest extends ApiTestCase
{
    use RefreshDatabaseTrait;

    /* some code */

    public function testGetCollection(): void
    {
        self::createClient()->request(Request::METHOD_GET, '/api/users');
        self::assertResponseStatusCodeSame(Response::HTTP_METHOD_NOT_ALLOWED);
    }

    /* some code */
}
