Codeception functional tests do not load any pages (only blank/empty pages)

Interesting. @sergeyklay will be able to help you on this for sure.

Hi, i try to use codeception functional test on phlacon project, and have same problem.

When i use echo, print() or var_dump() in my controller, then i can get output with $I->grabPageSource(). But when i use view to get output from controller ( fill view->content property with controller output), then $I->grabPageSource() return empty string. I try use _request and _loadPage methods to make request, but result was same.

I fiddle around with codeception for a few hours and i figured that handling application ($application->handle()) in Codeception/Lib/Connector/Phalcon dont render view.

I insert some outputs to Codeception/Lib/Connector/Phalcon->doRequest() function and get results in comments:

  public function doRequest($request)
  {
        // ...here is original code...

       // --- I ADD THIS ---
        var_dump($response->getContent());
        // string(0) ""
        $view = $di->get('view');
        var_dump($view->content);
        // array(3) {
        //   ["success"]=>
        //   bool(false)
        //   ["errorCode"]=>
        //   int(1)
        //   ["errorDesc"]=>
        //   string(13) "Invalid input"
        // }
        // -----------------------

        return new Response(
            $response->getContent(),
            $status ? $status : 200,
            $headers
        );
    }   

controller action :

    public function codeceptAction()
    {
        $this->view->layout = 'json';
        $this->view->content = [
            "someKey" => "some value"
        ];
    }

cest function:

     public function testCodeceptAction(\FunctionalTester $I) {
        $response = $I->callControllerAction('/test/codecept', []);
        var_dump($response);
    }

helper for function tester:

    public function callControllerAction($controllerUri, array $params = []) {
        $response = $this->getModule('Phalcon')->_request('POST', $controllerUri, $params);
        return $response;
    }

and finaly output from console:

But when i use view to get output from controller ( fill view->content property with controller output), then $I->grabPageSource() return empty string. I try use _request and _loadPage methods to make request, but result was same.

I solved it (see my answer here in the thread). In my case it was how I set the APP_PATH constant. It may be in your case too as I believe I copied it from one of the official docs.

Hey, you're right! My APP_PATH constant was wrong.

Iam angry with myself, becouse there was a problem with Phalcon\Loader in my aplication when i run tests, but i ignore it. And it should be a hint to me, that something is wrong with paths.

As usual, the problem was between the keyboard and the chair. :)

Thank you very much.
