phpspec doctrine queryBuilder - mock - symfony

Question

I'm writing a test in PHPSpec 2.0.0 that would use Doctrine query builder in a Symfony application. This is my class:
class RedirectHandle
{
/**
* #var string
*/
private $kernelEnvironment;
/**
* #var ContainerInterface
*/
private $container;
/**
* RedirectHandle constructor.
* #param $env
* #param ContainerInterface $containerInterface
*/
public function __construct($env, ContainerInterface $containerInterface)
{
$this->kernelEnvironment = $env;
$this->container = $containerInterface;
}
public function handleUrl($url)
{
if ($this->kernelEnvironment === "dev") {
$em = $this->container->get("doctrine")->getEntityManager();
return $em->createQuery("SELECT a FROM module_redirect a WHERE url_from_redirect = :url ")
->setParameter('url', $url)
->getSingleScalarResult();
}
return false;
}
}
Here is my phpspec test:
class RedirectHandleSpec extends ObjectBehavior
{
function let($kernel,$container,$queryBuilder,$em,$redirectHandle)
{
$env = "dev";
$kernel->beADoubleOf('Symfony\Component\HttpKernel\Kernel');
$kernel->getEnvironment()->willReturn($env);
$queryBuilder->beADoubleOf('Doctrine\ORM\QueryBuilder');
$container->beADoubleOf('Symfony\Component\DependencyInjection\ContainerInterface');
$redirectHandle->beADoubleOf('Kei\WebsiteBundle\Tools\Redirect\RedirectHandle');
$em->beADoubleOf('Doctrine\ORM\EntityManager');
$kernel->getContainer()->willReturn($container);
$this->beConstructedWith($env,$container);
}
function it_is_initializable()
{
$this->shouldHaveType('Kei\WebsiteBundle\Tools\Redirect\RedirectHandle');
}
function it_is_init_redirect_when_env_is_dev($container,$queryBuilder,$em)
{
$container->get("doctrine")->willReturn($queryBuilder);
$em->createQuery(Argument::any())->willReturn($em);
$this->handleUrl("test")->shouldBeReturn(true);
}
}
When I ran the test, I got the following error:
1PHP Fatal error: Uncaught Error: Call to a member function createQuery() on null in /var/www/kei-site/src/Kei/WebsiteBundle/Tools/Redirect/RedirectHandle.php:37

What should I do to fix this?

Answer 1

class RedirectHandle
{
/**
* #var string
*/
private $kernelEnvironment;
/**
* #var
*/
private $container;
/**
* RedirectHandle constructor.
* #param $env
* #param ContainerInterface $containerInterface
*/
public function __construct($env,ContainerInterface $containerInterface)
{
$this->kernelEnvironment = $env;
$this->container = $containerInterface;
}
/**
*
*/
public function handleUrl($url)
{
if ($this->kernelEnvironment === "dev") {
$em = $this->container->get("doctrine")->getEntityManager();
$query = $em->createQuery("SELECT a FROM KeiWebsiteBundle:Carrier a");
return true;
}
return false;
}
}
Phpspec code after refactor:
class RedirectHandleSpec extends ObjectBehavior
{
function let($kernel,$container,$queryBuilder,$em)
{
$env = "dev";
$kernel->beADoubleOf('Symfony\Component\HttpKernel\Kernel');
$queryBuilder->beADoubleOf('Doctrine\ORM\QueryBuilder');
$container->beADoubleOf('Symfony\Component\DependencyInjection\ContainerInterface');
$em->beADoubleOf('Doctrine\ORM\EntityManager');
$this->beConstructedWith($env,$container);
}
function it_is_initializable()
{
$this->shouldHaveType('Kei\WebsiteBundle\Tools\Redirect\RedirectHandle');
}
/**
* Przekierowuje strone jesli srodowisko jest dev
*/
function it_is_init_redirect_when_env_is_dev($container,$queryBuilder,$em)
{
$container->get("doctrine")->willReturn($queryBuilder);
$em->createQuery(Argument::any())->willReturn(new Query($em->getWrappedObject()));
$this->handleUrl("test");
}
}
