That would be great indeed, however this would require a completely
different approach, as I can't think of a way to automatically extract
this information by just parsing the script.

This could be considered a feature: if they were not listed, the user
would have no idea that they can be commented out.

OTOH I'm not sure why some tests are commented out in the first place,
it doesn't make much sense to me. Either they serve a purpose and they
should be enabled, or there is some kind of issue with them and they
should be either fixed or deleted altogether.
