        $this->routeMatch = new RouteMatch(['controller' => 'Task']);
        $this->event = new MvcEvent();
        $config = $serviceManager->get('Config');
        $routeConfig = isset($config['router']) ? $config['router'] : [];
        $router = HttpRouter::factory($routeConfig);

        $this->event->setRouter($router);
        $this->event->setRouteMatch($this->routeMatch);

        $this->controller->setServiceLocator($serviceManager);
