Silex 2升级后，WebTestCase失败

Question

I have the following base lass for controller tests:

public function createApplication() {
     include __DIR__ . '../web/index_dev.php';

     $app['debug'] = true;
     $app['session.test'] = true;
     $app['helper'] = function ($app) {
            return new TestHelper($app);
     }; // fails!!

     return $app;
  }

  public function setUp() {
     parent::setUp();

     $this->client = parent::createClient();
 }

At Silex 1.3 it worked fine, but after upgrade for v2 it fails at marked line. Once I comment it - everything is fine.

UPD#1: I figured out why it fails: Cannot override frozen service "helper". I understand the meaning of error, but can't understand how to fix it. It isa test case, so I need to replace it with mock/test implementation of object, but can't..

Answer 1

Your problem is the upgrade of the Pimple container. The Pimple version of Silex 2 freezes services once you get them .

So your problem is that you are getting the 'helper' service previously on your code. You should refactor your code so that you won't get the service when booting your application.
