Codeception - Depend on a test within a parent class - php

Question

Is it possible to have Cest files that extend a parent class and make use of a common test "login" that other tests depend on using the #depends
So my Cest file looks similar to the one found in this post which explains how to login and re-use the cookie in another test - https://stackoverflow.com/a/25547268/682754
I've got this common class but the test in the child class doesn't run and outputs...This test depends on 'commonCest::login' to pass.
<?php
class commonCest {
const COOKIE_NAME = 'PHPSESSID';
protected $cookie;
/**
* Most tests will need to depend on this function as it logs the user in and stores the session cookie, use the
* "#depends" phpdoc comment
*
* The cookie in then re-used by calling the following in tests:
*
* $I->setCookie(self::COOKIE_NAME, $this->cookie);
*
* #param \AcceptanceTester $I
*/
public function login(AcceptanceTester $I) {
$I->wantTo('Login');
$I->amOnPage('/login');
$I->fillField(array('name' => 'username'), 'aaaaaa');
$I->fillField(array('name' => 'password'), 'abcdef');
$I->click('.form-actions button');
$I->seeElement('.username');
$this->cookie = $I->grabCookie(self::COOKIE_NAME);
}
}
<?php
use \AcceptanceTester;
class rolesCest extends commonCest
{
/**
* #depends login (This doesn't work)
* #depends commonCest:login (This doesn't work)
* #depends commonCest::login (This doesn't work)
*/
public function listUsers(AcceptanceTester $I)
{
// tests
}
?>

Simply don't have commonCest under your cest directory. Login will then be run for every case of a class extending commonCest in your cest directory as it exists in all of them. You however shouldn't use #depends for this. Rather login should be in your actor or a helper, and that should be called from _before in your parent class.
Or just use stepobjects https://codeception.com/docs/06-ReusingTestCode#stepobjects and call your needed functions from _before
