php - How to access static property of Laravel Controller in PhpSpec? -

i trying write class read routes given constructor it's constructed with. however, after 1h of googling didn't find how access getrouter method of laravel controller - because it's static function. i've tried many things of time got following error:

uncaught error: using $this when not in object context in
vendor/phpspec/prophecy/src/prophecy/doubler/generator/classcreator.php(49) :
eval()'d code:13
stack trace: #0 [internal function]: double\illuminate\routing\controller\p4::getrouter()

how can achieve or not possible phpspec?

my spec:

use illuminate\routing\controller; use phpspec\objectbehavior; use prophecy\argument;  class optiondescriberspec extends objectbehavior {      function let(controller $controller)     {       $this->beconstructedwith($controller);     }      function it_should_read_the_aviable_routes_of_the_controller()     {         $this->getcontroller()->getrouter()->shouldreturn('router');         $this->render()->shouldreturn('router');     } } 

my class:

use illuminate\routing\controller;  class optiondescriber {      /**      * @var controller      */     protected $controller;      /**      * optiondescriber constructor.      *      * @param controller $controller      */     public function __construct(controller $controller)     {         $this->controller = $controller;     }      public function render()     {         return $this->controller->getrouter();     } } 

function it_should_read_the_aviable_routes_of_the_controller(controller $controller, router $router) {     $this->getcontroller()->willreturn($controller);     $controller->getrouter()->willreturn($router);      $this->render()->shouldreturn($router); } 

alltough it's not recommended spec controllers. make controller thin possible , move 'meat' service used controller.
