Debugging and Profiling Symfony2
Symfony2 projects can be debugged and profiled without any Symfony2-specific configuration. The standard PhpStorm debugging or profiling workflows are sufficient.
Unit Testing Symfony2
The PHPUnit configuration file that can be used for unit testing Symfony2 applications can be found under phpunit.xml.dist. This file can be renamed to phpunit.xml and configured as the test configuration file under Project Settings | PHP | PHPUnit.
