codeception - Yii2 url generation issue -

in yii2 codeception acceptance test using phantomjs browser.

started server

 phantomjs --webdriver=4444 

when running test

codecept run 

it isn't working expected.
code is:

class logincest {     public function ensurethatloginworks(acceptancetester $i)     {         $i->amonpage(url::toroute('/site/login'));         $i->see('enq','b');      } } 

when changing to

$i->amonpage(url::toroute(['/../../../site/login'])); 

its works fine because takes url myapp/web/usr/local/bin/site/login

its adding automatically usr/local/bin

is there solution apart $i->amonpage(url::toroute(['/../../../site/login']));

worked fine whe replacing

 $i->amonpage(url::toroute(['/../../../site/login'])); 

with this

$i->amonpage('/site/login');
