Yii2 advance template testing path issue

I have brand new advance template and has problem with using short cut for test suite.




#current working directory is

/www/yii-advance-test/tests/codeception/frontend


#this does not work

codecept run unit SignupFormTest.php:testCorrectSignup => throw exception [Exception] File or path SignupFormTest.php not found


#this work

codecept run unit unit/models/SignupFormTest.php:testCorrectSignup



how do I make the shortcut works ? (Codeception has documentation for shortcut @ http://codeception.com/docs/02-GettingStarted#.Vrk9XlgrKUk)
