various modernizations

modernized / clarified variable names in tests, culled erroneous files, tiny formatting improvements
I've yet to find a reason or even a purpose that a test bundle needs/wants an `info.plist`.  Obviously, I hate all the ridiculous files in the standard templates..  but I'm a bit OCD when I start purging...  That said, I've done it so many times.. I really know what's totally safe to boot.  but I'm used to people's alarm (mommy/apple said complex)... but I'm just not that sentimental.
