I am using PhpStorm 2016.2 and my code is not working properly. When entering $this->assertCo

it only offers function names that are the ancestors of the third level of my class. But when I use Ctrl + Space , it offers the correct elements.

This is the diagram of my class:

and missing sentences are in the PHPUnit_Framework_Assert class.
How can I make it work without using Ctrl + Space every time?
