I have a backend system based on Symfony 3.x, and I work on PHPStorm 2017.x. My Server is a regular XAMPP 5.6.8 stack with Apache and MySQL only, and I applied the latest compatible phpunit.phar (5.7.20) to the "php"-folder in the XAMPP-directory. I am supposed to run PHPUnit tests with a Phing buildfile, however the internal PHPStorm terminal displays an error:
Fatal error: Class 'PHPUnit\Framework\TestCase' not found in O:\%PROJECT_DIR%\vendor\symfony\symfony\src\Symfony\Bundle\FrameworkBundle\Test\KernelTestCase.php on line 25
In my current project settings, I pointed to the phpunit.phar within my XAMPP-directory, but somehow it still tries to find the phpunit within the Symfony vendor directory. Where exactly is the source of the error and how can I correct it? Is it Phing-based?
EDIT: Adding the error call stack:

PHPUnit\Framework\TestCase is a reference to PhpUnit 6 test version while you're using phpunit.phar (5.7.20). Try to replace it with the latest 6.* version.
