PHPUnit 6: No test case / test suite found for file

[JercSi]

Class 'PHPUnit_Framework_TestCase' does not exist in PHPUnit 6.

I changed the SuperClass to 'PHPUnit\Framework\TestCase', 'TestCase', to blank value,... and result is always 'Error: No test case / test suite found for file '.

If i set PHPUnit back to 5.7 with using namespaces it still does not work. But when i change back to 'extends PHPUnit_Framework_TestCase' it's working. No matter what i have in 'SuperClass'.

Any idea how to make Eclipse to work with PHPUnit 6+?
