x.py test should be able to test subfolders

[varkor]

It would be very useful if ./x.py test src/test/ui/subfolder would run every UI test in src/test/ui/subfolder (at the moment it runs every single UI test). ./x.py test currently works for individual files and for entire test suites, but not directories.

The --test-args flag might become obsolete if this becomes possible.

Please no... :) --test-args is still useful for testing files that have similar names or if you are just too lazy to give an absolute path.

The most useless feature ever.
