Example #1

File: EsiListenerTest.php Project: rooster/symfony

 public function testFilterWhenThereIsNoEsiIncludes()
 {
     $dispatcher = new EventDispatcher();
     $listener = new EsiListener(new Esi());
     $dispatcher->connect('core.response', array($listener, 'filter'));
     $event = new Event(null, 'core.response', array('request_type' => HttpKernelInterface::MASTER_REQUEST));
     $dispatcher->filter($event, $response = new Response('foo'));
     $this->assertEquals('', $response->headers->get('Surrogate-Control'));
 }

Example #2

File: EventDispatcherTest.php Project: rooster/symfony

 public function testFilter()
 {
     $listener = new Listener();
     $dispatcher = new EventDispatcher();
     $dispatcher->connect('foo', array($listener, 'filterFoo'));
     $dispatcher->connect('foo', array($listener, 'filterFooBis'));
     $ret = $dispatcher->filter($event = new Event(new \stdClass(), 'foo'), 'foo');
     $this->assertEquals('-*foo*-', $ret, '->filter() returns the filtered value');
     $listener->reset();
     $dispatcher = new EventDispatcher();
     $dispatcher->connect('foo', array($listener, 'filterFooBis'));
     $dispatcher->connect('foo', array($listener, 'filterFoo'));
     $ret = $dispatcher->filter($event = new Event(new \stdClass(), 'foo'), 'foo');
     $this->assertEquals('*-foo-*', $ret, '->filter() returns the filtered value');
 }
