Failed to stay loggedin with phpbrowser

[vl-ivanov]

Hello!

I have installed user-management module on top of Yii2 advaced template and I am trying to write codeception functional test about the login form. That's the test verbose log:

codecept run backend/tests/ -vvv

 I see "User Management"
 FAIL 

  [Database] Transaction cancelled; all changes reverted.

There seem to be a problem maintaining session because it's clear by the log that user 1 is logged in successfully and right after that is redirected to http://localhost/index-test.php. Fair enough, but no session cookie is passed and so http://localhost/index-test.php redirects user again to the login form on http://localhost/index-test.php/user-management.

Any ideas what's wrong? Already tried to login via normal web browser using the test configuration and there is no problem.
